Rapid transit or mass rapid transit ( MRT ) or heavy rail , commonly referred to as metro , is a type of high-capacity public transport that is generally built in urban areas . A grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway , tube , metro or underground . They are sometimes grade-separated on elevated railways , in which case some are referred to as el trains – short for "elevated" – or skytrains . Rapid transit systems are railways , usually electric , that unlike buses or trams operate on an exclusive right-of-way , which cannot be accessed by pedestrians or other vehicles.
174-575: The IND Eighth Avenue Line is a rapid transit line in New York City , United States , and is part of the B Division of the New York City Subway . Opened in 1932, it was the first line of the Independent Subway System (IND); as such, New Yorkers originally applied the Eighth Avenue Subway name to the entire IND system. The line runs from 207th Street in Inwood south to an interlocking south of High Street in Brooklyn Heights , including large sections under St. Nicholas Avenue , Central Park West , and Eighth Avenue . The entire length
348-719: A subway line in New York City dates to 1864. However, development of what would become the city's first subway line did not start until 1894, when the New York State Legislature passed the Rapid Transit Act. The subway plans were drawn up by a team of engineers led by William Barclay Parsons , the Rapid Transit Commission's chief engineer. It called for a subway line from New York City Hall in lower Manhattan to
522-489: A band of green tile, while the tops of the walls and the ceilings are made of concrete. Two footbridges with staircases connect the platforms. The elevators rise 76 feet (23 m) to the upper mezzanine level, which connects with the IND platforms. A rear passageway at the lower mezzanine level allows passengers to board and alight on different sides of the elevator cabs. The northern open bridge and northbound platform features
696-425: A body of water), which are potential congestion sites but also offer an opportunity for transfers between lines. Ring lines provide good coverage, connect between the radial lines and serve tangential trips that would otherwise need to cross the typically congested core of the network. A rough grid pattern can offer a wide variety of routes while still maintaining reasonable speed and frequency of service. A study of
870-454: A code for its stations. Unlike that of Singapore's MRT, it is mostly numbers. Based on the line number, for example Sinyongsan station, is coded as station 429. Being on Line 4, the first number of the station code is 4. The last two numbers are the station number on that line. Interchange stations can have multiple codes. Like City Hall station in Seoul which is served by Line 1 and Line 2. It has
1044-651: A code of 132 and 201 respectively. The Line 2 is a circle line and the first stop is City Hall, therefore, City Hall has the station code of 201. For lines without a number like Bundang line it will have an alphanumeric code. Lines without a number that are operated by KORAIL will start with the letter 'K'. With widespread use of the Internet and cell phones globally, transit operators now use these technologies to present information to their users. In addition to online maps and timetables, some transit operators now offer real-time information which allows passengers to know when
1218-583: A conventional track is often provided in case of flat tires and for switching . There are also some rubber-tired systems that use a central guide rail , such as the Sapporo Municipal Subway and the NeoVal system in Rennes , France. Advocates of this system note that it is much quieter than conventional steel-wheeled trains, and allows for greater inclines given the increased traction of
1392-405: A dedicated right-of-way are typically used only outside dense areas, since they create a physical barrier in the urban fabric that hinders the flow of people and vehicles across their path and have a larger physical footprint. This method of construction is the cheapest as long as land values are low. It is often used for new systems in areas that are planned to fill up with buildings after the line
1566-443: A free out-of-system transfer was provided to the A train at Inwood–207th Street , from both 207th Street and 215th Street . The IND station was planned to be renovated starting in 2016 as part of the 2010–2014 MTA Capital Program. An MTA study conducted in 2015 found that 48 percent of components in the IND station were out of date. According to a study conducted by New York University researchers and published in 2024,

A transit system is expected to serve an area of land with a set of lines , which consist of shapes summarized as "I", "L", "U", "S", and "O" shapes or loops. Geographical barriers may cause chokepoints where transit lines must converge (for example, to cross
1914-652: A large part of the network, for example, in outer suburbs, runs at ground level. In most of Britain , a subway is a pedestrian underpass . The terms Underground and Tube are used for the London Underground . The North East England Tyne and Wear Metro , mostly overground, is known as the Metro . In Scotland , the Glasgow Subway underground rapid transit system is known as the Subway . In Ireland ,

#17327717747742088-452: A line is obtained by multiplying the car capacity, the train length, and the service frequency . Heavy rapid transit trains might have six to twelve cars, while lighter systems may use four or fewer. Cars have a capacity of 100 to 150 passengers, varying with the seated to standing ratio – more standing gives higher capacity. The minimum time interval between trains is shorter for rapid transit than for mainline railways owing to
2262-649: A lower level of the 50th Street station, and merges to the south, taking E trains onto the local tracks. An unused southbound-only lower level at 42nd Street–Port Authority Bus Terminal was formerly accessed only from the southbound track from the Queens Boulevard Line. Plans for the 7 Subway Extension required partially demolishing the lower level to make room for the new IRT Flushing Line tracks. The four-track line continues south under Eighth Avenue to 14th Street , where it turns southeast under Greenwich Avenue and south under Sixth Avenue , above
2436-615: A metro. In Spain, such systems are present in Madrid , Barcelona , Bilbao and Valencia . In Portugal, Lisbon has a metro. The Italian cities of Catania , Genoa , Milan , Naples , Rome and Turin also have metro lines. In Germany and Austria they rapid transit is known as U-Bahn , which are often supported by S-Bahn systems. In Germany, U-Bahn systems exist in Berlin , Hamburg , Munich and Nuremberg , while in Austria such
2610-415: A passageway east of the northbound side to an eastern elevator shaft. This shaft contained the two original elevators to and from the platforms. Each shaft measured 15 by 32 feet (4.6 by 9.8 m) wide. The eastern elevator shaft are planned to be reused for ADA accessibility to at least the northbound platform. There is also a stairway on the extreme northern end of both platforms, which ascends to
2784-517: A point 100 feet (30 m) north of 182nd Street. Work on this section was conducted by L. B. McCabe & Brother, who started building the tunnel segment on May 14, 1900. The 168th Street station was one of three stations to be built within the deep-level Fort George Mine Tunnel. The station was equipped with elevators from its opening, since the IRT's contract with the city mandated elevators in stations that were more than 29 feet (8.8 m) deep. At

Located at the intersection of 168th Street and Broadway in the Washington Heights neighborhood of Manhattan , it
3306-446: A relay and signal power room. This stairway is not visible to the public. Much of the station is contained within a vault that measures 47 feet (14 m) wide and 26 feet (7.9 m) high. The lowest 6 feet (1.8 m) of the vault walls are wainscoted with rust-colored brick. Atop the brick wainscoting are a belt course made of marble and a multicolored mosaic frieze measuring about 16 inches (410 mm) thick. The tops of
3480-552: A result of the cuts after an elevator operator at 181st Street on the Broadway–Seventh Avenue Line helped save a stabbed passenger. The move was intended to save $ 1.7 million a year. However, on December 7, 2007, the MTA announced that it would not remove the remaining elevator operators at these stations, due to pushback from elected officials and residents from the area. In October 2018, the MTA once again proposed removing
3654-487: A set of 119 steps; this contributed to serious overcrowding on the station's first day of operation. On May 30, 1906, express trains began running through to 221st Street. The opening of the first subway line helped contribute to the development of Washington Heights , although development around the 168th Street station was initially limited because of the presence of American League Park, as well as covenants that restricted development on many lots west of Broadway. When

#17327717747743828-565: A specialized transit police may be established. These security measures are normally integrated with measures to protect revenue by checking that passengers are not travelling without paying. Some subway systems, such as the Beijing Subway , which is ranked by Worldwide Rapid Transit Data as the "World's Safest Rapid Transit Network" in 2015, incorporates airport-style security checkpoints at every station. Rapid transit systems have been subject to terrorism with many casualties, such as
4002-608: A system exists in Vienna . In addition, the small, car-free town of Serfaus in the Austrian state of Tyrol also features a short U-Bahn line. There are no U-Bahn systems in the German-speaking part of Switzerland, but the city of Lausanne has its own, small metro system. In Zurich, Switzerland's largest city, a project for a U-Bahn network was stopped by a referendum in the 1970s and instead its S-Bahn system
4176-506: A temporary terminus at 221st Street , near the Harlem River Ship Canal , on March 12, 1906, with the station at 168th Street not yet open. This extension was initially served by shuttle trains operating between 157th Street and 221st Street. The 168th Street station opened for service on April 14, 1906. The station originally only had two elevators, each measuring 12 by 12 feet (3.7 m × 3.7 m), as well as
4350-484: A ventilation shaft for the IRT station in 1993 to alleviate overheating. During the early 1990s, the MTA also removed three of the station's high entry-exit turnstiles to increase passenger flow. The IRT station's elevators gained a reputation for unreliability. Newsday , in 1992, reported that one of the station's elevators had recorded 40 outages in six months and was non-functional for a quarter of that time. Between July 5 and September 8, 1997, trains did not stop at
4524-801: Is a shortened reference to a metropolitan area . Rapid transit systems such as the Washington Metrorail , Los Angeles Metro Rail , the Miami Metrorail , and the Montreal Metro are generally called the Metro . In Philadelphia , the term "El" is used for the Market–Frankford Line which runs mostly on an elevated track, while the term "subway" applies to the Broad Street Line which is almost entirely underground. Chicago 's commuter rail system that serves
4698-608: Is a single corporate image for the entire transit authority, but the rapid transit uses its own logo that fits into the profile. A transit map is a topological map or schematic diagram used to show the routes and stations in a public transport system. The main components are color-coded lines to indicate each line or service, with named icons to indicate stations. Maps may show only rapid transit or also include other modes of public transport. Transit maps can be found in transit vehicles, on platforms , elsewhere in stations, and in printed timetables . Maps help users understand
4872-474: Is between 181st Street to the north and 157th Street to the south. It is one of three in the deep-level Fort George Mine Tunnel, along with the 181st Street and 191st Street stations to the north; the tunnel allows the Broadway–Seventh Avenue Line to travel under the high terrain of Washington Heights. Sources disagree on the station's depth, which has been variously cited as 99 feet (30 m), 100 feet (30 m), or 117 feet (36 m). The station
5046-506: Is built. Most rapid transit trains are electric multiple units with lengths from three to over ten cars. Crew sizes have decreased throughout history, with some modern systems now running completely unstaffed trains. Other trains continue to have drivers, even if their only role in normal operation is to open and close the doors of the trains at stations. Power is commonly delivered by a third rail or by overhead wires . The whole London Underground network uses fourth rail and others use
5220-416: Is necessary, rolling stock with a smaller loading gauge from one sub network may be transported along other lines that use larger trains. On some networks such operations are part of normal services. Most rapid transit systems use conventional standard gauge railway track . Since tracks in subway tunnels are not exposed to rain , snow , or other forms of precipitation , they are often fixed directly to
5394-586: Is now used for New York City Transit employees only. The western area was closed in the 1980s for safety reasons, while the eastern area was closed in 1992. The 168th Street station (sometimes announced on the trains as the Washington Heights-168th Street station ) on the IRT Broadway–Seventh Avenue Line has two tracks and two side platforms , and is served by the 1 train at all times. The station

5568-529: Is one of three stations in the New York City Subway system that can be accessed solely by elevators. The other two, also located on the Broadway–Seventh Avenue Line, are 181st Street one stop to the north, as well as Clark Street on the 2 and 3 trains in Brooklyn . However, the IRT station is not ADA-accessible . As part of the 2017 Fast Forward plan to modernize
5742-592: Is present on the east side of the tunnel. It has been proposed to use this to bring Long Island Rail Road Atlantic Branch trains to Lower Manhattan as part of the Lower Manhattan-Jamaica/JFK Transportation Project . The four tracks continue south under Church Street, with two separate but connected stations at World Trade Center at the end of the local tracks and Chambers Street on the express tracks. The two express tracks turn east under Fulton Street , crossing
5916-555: Is referred to simply as "the subway", despite 40% of the system running above ground. The term "L" or "El" is not used for elevated lines in general as the lines in the system are already designated with letters and numbers. The "L" train or L (New York City Subway service) refers specifically to the 14th Street–Canarsie Local line, and not other elevated trains. Similarly, the Toronto Subway is referred to as "the subway", with some of its system also running above ground. These are
6090-587: Is served by the 1 and A trains at all times, and is the northern terminal for the C train at all times except late nights, when it does not run. The Broadway–Seventh Avenue Line station was built for the Interborough Rapid Transit Company (IRT), and was a station on the West Side Branch of the city's first subway line , which was approved in 1900. The station opened on April 14, 1906. The Eighth Avenue Line station
6264-412: Is serviced by at least one specific route with trains stopping at all or some of the line's stations. Most systems operate several routes, and distinguish them by colors, names, numbering, or a combination thereof. Some lines may share track with each other for a portion of their route or operate solely on their own right-of-way. Often a line running through the city center forks into two or more branches in
6438-748: Is the most commonly used term for underground rapid transit systems used by non-native English speakers. Rapid transit systems may be named after the medium by which passengers travel in busy central business districts ; the use of tunnels inspires names such as subway , underground , Untergrundbahn ( U-Bahn ) in German, or the Tunnelbana (T-bana) in Swedish. The use of viaducts inspires names such as elevated ( L or el ), skytrain , overhead , overground or Hochbahn in German. One of these terms may apply to an entire system, even if
6612-565: Is the northernmost express station on the Eighth Avenue Line, the color-coded tiles at stations north of 168th Street were originally maroon, This station has a full length mezzanine above the platforms and tracks. Black I-beam columns run along the platform, alternating ones having the standard black name plate with white lettering. Nearby points of interest include NewYork-Presbyterian Hospital / Columbia University Medical Center , Fort Washington Armory , Fort Washington Park on
6786-487: Is underground, though the 207th Street Yard , which branches off near the north end, is on the surface. Flying junctions are provided with the IND Concourse Line , IND Sixth Avenue Line , and IND Queens Boulevard Line . Most of the line has four tracks, with one local and one express track in each direction, except for the extreme north and south ends, where only the two express tracks continue. Internally,
6960-524: The Broadway and Lexington Avenue lines, were instead built using the cut-and-cover method. In Fiscal Year 1909, work was done to increase the carrying load of the elevators at the station. Officials had decided against adding additional elevators because it would only cost $ 6,300 to update the existing elevator cabs. By the early 1910s, the elevators could carry 80 people at once and were staffed by elevator operators. To address overcrowding, in 1909,

In France, large cities, such as Paris , Marseille and Lyon , feature a Métro . Also the smaller cities of Lille Rennes have a light metro. Furthermore, Brussels in Belgium, and Amsterdam and Rotterdam in the Netherlands have metro systems in place. Several Southern European contries also have

These alternatives would have required that C trains be rerouted through the Rutgers Street Tunnel . In the wake of the September 11, 2001 attacks , World Trade Center station was temporarily unusable as a terminal for
8178-740: The Metropolitan Railway opened publicly in London in 1863. High capacity monorails with larger and longer trains can be classified as rapid transit systems. Such monorail systems recently started operating in Chongqing and São Paulo . Light metro is a subclass of rapid transit that has the speed and grade separation of a "full metro" but is designed for smaller passenger numbers. It often has smaller loading gauges, lighter train cars and smaller consists of typically two to four cars. Light metros are typically used as feeder lines into
8352-578: The Montreal Metro (opened 1966) and Sapporo Municipal Subway (opened 1971), their entirely enclosed nature due to their use of rubber-tyred technology to cope with heavy snowfall experienced by both cities in winter precludes any air-conditioning retrofits of rolling stock due to the risk of heating the tunnels to temperatures that would be too hot for passengers and for train operations. In many cities, metro networks consist of lines operating different sizes and types of vehicles. Although these sub-networks may not often be connected by track, in cases when it
8526-637: The New York City Board of Estimate approved the Washington Heights Line , an extension of the Broadway Line to Washington Heights. The line was to have four tracks from Central Park West at 64th Street under Central Park West, Eighth Avenue, Saint Nicholas Avenue , and private property to 173rd Street, and two tracks under Fort Washington Avenue to 193rd Street. South of 64th Street, one two-track line would connect to
8700-545: The New York Public Service Commission proposed lengthening the platforms at stations along the original IRT subway. As part of a modification to the IRT's construction contracts made on January 18, 1910, the company was to lengthen station platforms to accommodate ten-car express and six-car local trains. In addition to $ 1.5 million (equivalent to $ 49.1 million in 2023) spent on platform lengthening, $ 500,000 (equivalent to $ 16.4 million in 2023)
8874-589: The Prague Metro . The London Underground and Paris Métro are densely built systems with a matrix of crisscrossing lines throughout the cities. The Chicago 'L' has most of its lines converging on The Loop , the main business, financial, and cultural area. Some systems have a circular line around the city center connecting to radially arranged outward lines, such as the Moscow Metro 's Koltsevaya Line and Beijing Subway 's Line 10 . The capacity of

Interchange stations have at least two codes, for example, Raffles Place MRT station has two codes, NS26 and EW14, the 26th station on the North South Line and the 14th station on the East West Line. The Seoul Metro is another example that utilizes
9222-604: The Upper West Side , where two branches would lead north into the Bronx . A plan was formally adopted in 1897, and all legal conflicts concerning the route alignment were resolved near the end of 1899. The Rapid Transit Construction Company, organized by John B. McDonald and funded by August Belmont Jr. , signed the initial Contract 1 with the Rapid Transit Commission in February 1900, under which it would construct
9396-450: The deep tube lines . Historically, rapid transit trains used ceiling fans and openable windows to provide fresh air and piston-effect wind cooling to riders. From the 1950s to the 1990s (and in most of Europe until the 2000s), many rapid transit trains from that era were also fitted with forced-air ventilation systems in carriage ceiling units for passenger comfort. Early rapid transit rolling stock fitted with air conditioning , such as
9570-409: The linear motor for propulsion. Some urban rail lines are built to a loading gauge as large as that of main-line railways ; others are built to a smaller one and have tunnels that restrict the size and sometimes the shape of the train compartments. One example is most of the London Underground , which has acquired the informal term "tube train" due to the cylindrical shape of the trains used on

Rapid transit operators have often built up strong brands , often focused on easy recognition – to allow quick identification even in the vast array of signage found in large cities – combined with the desire to communicate speed, safety, and authority. In many cities, there
9918-635: The 168th Street IRT station had some of the highest particulate matter pollution levels of any subway station in New York City. After the first subway line was completed in 1908, the station was served by West Side local and express trains. Express trains began at South Ferry in Manhattan or Atlantic Avenue in Brooklyn, and ended at 242nd Street in the Bronx. Local trains ran from City Hall to 242nd Street during rush hours, continuing south from City Hall to South Ferry at other times. In 1918,
10092-408: The 168th Street station on the Eighth Avenue Line was among the subway system's 12 worst bottlenecks for passenger flow. The New York City Transit Authority (NYCTA) was considering renovating the 168th Street station by 1975. The station's token booth was closed at some point during the 1970s but reopened in 1979. The Broadway–Seventh Avenue Line station was renovated in the late 1980s. By 1988,
10266-551: The 168th Street station opened, the two elevators could fit only 50 passengers each, and they became severely overcrowded during peak times. During baseball games at American League Park, many fans opted to instead take the subway to 157th Street, then pay an additional 25 cents for a taxi to the stadium. The elevators' capacity limitations prompted the Public Service Commission to decide against constructing additional deep-level subway lines; newer routes, such as
10440-509: The 168th Street station, the only means of access was via two elevators and a staircase, and the station cavern extended 150 feet (46 m) north and south of 168th Street. The original New York City Subway line from City Hall to 145th Street on the West Side Branch opened in October 1904, with the line being extended to 157th Street a week later. The 168th and 181st Street stations had been scheduled to open on May 1, 1905, but

On August 23, 1930, bids on the construction of the connection (bellmouths) between the Eighth Avenue Line and the proposed Worth Street Line were put up for bid by
11310-602: The Board of Transportation. These bellmouths were constructed to allow work on the Worth Street Line to be done without interrupting service on the Eighth Avenue Line. This route was expected to the first line of the IND Second System to be built. At the time it was anticipated that the line would open a year or so after the completion of the Eighth Avenue Line under the East River to Brooklyn. However,
11484-440: The Broadway Line stubs at 57th Street, and another would continue under Eighth Avenue to 30th Street at Penn Station , with provisions to continue downtown. Mayor John Hylan instead wanted to build an independent subway system, operated by the city. The New York City Board of Transportation (NYCBOT) gave preliminary approval to several lines in Manhattan, including one on Eighth Avenue, on December 9, 1924. The main portion of
11658-420: The Broadway–Seventh Avenue Line opened south of Times Square–42nd Street , and the original line was divided into an H-shaped system. The original subway north of Times Square thus became part of the Broadway–Seventh Avenue Line. Local trains were sent to South Ferry , while express trains used the new Clark Street Tunnel to Brooklyn. The IRT routes at the station were given numbered designations in 1948 with
11832-419: The Broadway–Seventh Avenue Line through the implementation of a skip-stop service: the 9 train. When skip-stop service started in 1989, it was only implemented north of 137th Street–City College on weekdays, and 168th Street was served by both the 1 and the 9. Skip-stop service ended on May 27, 2005, as a result of a decrease in the number of riders who benefited. The A express train has always served
12006-628: The C's route. The B and the C, which both ran local along Central Park West, switched northern terminals on March 1, 1998, ending the connection between the C and the Bronx. Instead of alternating between three different terminals depending on the time of day, all C service now terminated at 168th Street. A report for the Lower Manhattan Development Corporation looking at the Lower Manhattan Rail Link , an idea to connect Lower Manhattan with
12180-732: The Concourse Line, forcing A trains to run local north of 145th Street . The E was added to the local tracks south of 50th Street on August 19, 1933, when the IND Queens Boulevard Line opened. The final major change came on December 15, 1940, when the IND Sixth Avenue Line opened. The AA was brought back as a non-rush hour local service, becoming the BB and switching to the Sixth Avenue Line at 59th Street–Columbus Circle during rush hours. The CC
12354-533: The E. C service was suspended until September 24, 2001. Local service along Central Park West was replaced by the A and D, and the E was extended from Canal Street to Euclid Avenue replacing C service in Brooklyn. On January 23, 2005, a fire at the Chambers Street signal room crippled A and C service. C service was suspended until February 2 and was replaced by the A, B, D, E, and V trains along different parts of its route. Initial assessments suggested that it would take several years to restore normal service, but
12528-623: The IND Eighth Avenue Line. The line would have branched off of the line's local tracks at the intersection of Church Street and Franklin Street to the south of the Canal Street station and would have turned southeast into Worth Street . This route would have traveled in a two-track tunnel. It would have probably stopped at Foley Square ( Lafayette and Centre Streets, on the north side of Federal Plaza), Chatham Square (with
12702-588: The IND station since its inception in 1932. Local service was initially provided by the AA train from 168th Street to Chambers Street/Hudson Terminal ; at the time, local services were denoted by double letters and express services by single letters. The AA was discontinued in 1933 when the CC began running on the local tracks along the Eighth Avenue and Concourse lines. The original BB train started running with
12876-456: The IRT station were replaced with automatic ones, which began operating in January 1958. Fluorescent lighting at the IRT station was installed during Fiscal Year 1961. The 168th Street station was a major transfer hub for interstate buses to New Jersey until the 1960s, when the nearby George Washington Bridge Bus Station opened; the last interstate bus stop was relocated in 1967. By 1970,
13050-491: The IRT station while the elevators were modernized. The NYCTA opted to close the station entirely because it would have taken two years to replace the elevators one at a time and because the staircase to the station could not handle the 18,000 passengers that used the station every day. A shuttle bus service was provided to 181st Street on the Broadway–Seventh Avenue Line during the station's closure. The project cost $ 4 million (equivalent to $ 7.6 million in 2023). Several of
13224-657: The IRT subway stop there. The Transit Commission proposed another subway line to Broadway and 168th Street, an unbuilt extension of the Brooklyn–Manhattan Transit Corporation 's Broadway Line , in 1922. New York City mayor John Francis Hylan 's original plans for the Independent Subway System (IND), proposed in 1922, included building over 100 mi (160 km) of new lines and taking over nearly 100 mi (160 km) of existing lines. The lines were designed to compete with
13398-585: The IRT's operations on June 12, 1940. Platforms at IRT Broadway–Seventh Avenue Line stations between 103rd Street and 238th Street , including those at 168th Street, were lengthened to 514 feet (157 m) between 1946 and 1948, allowing full ten-car express trains to stop at these stations. A contract for the platform extensions at 168th Street and eight other stations on the line was awarded to Spencer, White & Prentis Inc. in October 1946, with an estimated cost of $ 3.891 million. The platform extensions at these stations were opened in stages. On April 6, 1948,
13572-488: The K designation was discontinued and merged into the C, which now ran at all times except late nights. The C ran from Bedford Park Boulevard to Rockaway Park during rush hours, 145th Street to Euclid Avenue during middays, and from 145th Street to World Trade Center during evenings and weekends. The A now ran express in Brooklyn during middays, and the B was extended to 168th Street during middays and early evenings. On May 29, 1994, weekend C service between 7 a.m. and 11 p.m.
13746-459: The K in 1985, while the BB was renamed the B. The K train was completely replaced by the C 's midday service on December 11, 1988, with all local service at 168th Street being provided by the B. On March 1, 1998, the B and the C switched northern terminals, ending B service to Washington Heights; the C began serving the station at all times except late nights. The IRT platforms are very deep, with
13920-463: The Lower East Side, would have been the line's terminal. Construction was expected to begin in 1937 and be complete by 1944. In 1938 the cost of the line was pegged by the BOT to be $ 16.73 million. Even though these bellmouths were never used and the line was never completed, the bellmouths are still visible south of Canal Street adjacent to the local tracks. Other provisions were built in anticipation of
14094-489: The MTA announced that as part of its 2004 budget it would eliminate 22 elevator operator positions at the IRT's 168th Street station and four others in Washington Heights, leaving one full-time operator per station. The agency had intended to remove all the attendants at these stops, but kept one in each station after many riders protested. In addition, the MTA began operating all elevators at all times; prior to
14268-517: The Sixth Avenue Line through Midtown Manhattan. The following services use part or all of the Eighth Avenue Line. The trunk line's bullets are colored blue: The Eighth Avenue Line begins as a two-track subway under Broadway at 207th Street in Inwood . A flying junction just to the south brings two tracks from the 207th Street Yard between the main tracks, merging after Dyckman Street . The subway leaves Broadway to pass under Fort Tryon Park to
14442-468: The already-approved Washington Heights Line—the mostly-four track line north of 64th Street—was included, but was to continue north from 193rd Street to 207th Street. South of 64th Street, the plan called for four tracks in Eighth Avenue, Greenwich Avenue , the planned extension of Sixth Avenue , and Church Street . Two tracks would turn east under Fulton Street or Wall Street and under the East River to Downtown Brooklyn . A groundbreaking ceremony
14616-411: The average elevator in the New York City Subway system. By then, the elevators broke down hundreds of times per year, inconveniencing passengers who needed to travel to Columbia University Medical Center. From January 5 to December 20, 2019, the IRT station was closed so the elevator cars could be replaced, and elevator shafts, mechanical components, and the stairways could be upgraded. During this time,
14790-478: The beginning of rapid transit. Initial experiences with steam engines, despite ventilation, were unpleasant. Experiments with pneumatic railways failed in their extended adoption by cities. In 1890, the City & South London Railway was the first electric-traction rapid transit railway, which was also fully underground. Prior to opening, the line was to be called the "City and South London Subway", thus introducing
14964-419: The bridge, as well as two commuter rail tracks. However, when the lower level was added in 1962, it instead carried a roadway. The two main tracks from Fort Washington Avenue enter Broadway near 172nd Street, curving and running underneath a public school (PS173M) at 174th Street, and other private property, and the yard tracks in a double-decker tunnel. A few blocks later, the lower tracks separate to straddle
15138-466: The caverns and elevator shafts at these stations were not even fully excavated at the beginning of that year. Workers wanted to expedite the line's opening to serve baseball fans traveling to American League Park , the home of the Highlanders (now New York Yankees ), which occupied the western side of Broadway from 165th to 168th Street. A train crashed into a temporary bulkhead at the south end of
15312-489: The change, each elevator only operated if it was staffed by an elevator operator. The change took effect on January 20, 2004, and was expected to save $ 1.15 million a year. In November 2007, the MTA proposed savings cuts to help reduce the agency's deficit. As part of the plan, all elevator operators at 168th Street, along with those in four other stations in Washington Heights, would have been cut. MTA employees had joined riders in worrying about an increase in crime as
15486-458: The city-operated IND's initial segment, the Eighth Avenue Line between Chambers Street and 207th Street . There was a direct connection with the IRT station at 168th Street; initially, passengers had to pay an additional fare to transfer between the IRT and the IND. Construction of the whole line cost $ 191.2 million (equivalent to $ 4,269.8 million in 2023). While the IRT Broadway–Seventh Avenue Line already provided service to Washington Heights,
15660-538: The closed entrance had recorded over 50 felonies per year, some locals opposed the closure because it would create inconvenience. Passengers also frequently complained that the IRT station was overheating during the summer, prompting the Metropolitan Transportation Authority (MTA) to operate one of the station's fans all the time in 1991. This was not repeated during 1992 because one of the station's fans had broken. The MTA installed
15834-422: The construction of a two-level subway structure. In January 1929, the city paid money awarded to adjacent property owners for property taken and awarded contracts for 15 feet (4.6 m)-wide sidewalks and a 60 feet (18 m)-wide roadway. The sidewalks had been 10 feet (3.0 m) wide and the roadway had been 20 feet (6.1 m) wide. New buildings were built on the west sides of Church Street. The east side of
16008-495: The construction of the line was delayed due to the city's lack of funding after 1932. The Board of Transportation resumed efforts to build the line after a study of existing conditions in the area was completed, and on the basis that funding would be provided from government and private sources. The plans were truncated to a three-stop crosstown line entirely within Manhattan. Stops would have been located at Foley Square, Rutgers Street, and Lewis Street. The Lewis Street stop, located in
16182-996: The construction of the line. A large open space above the platform level at the East Broadway station on the Sixth Avenue Line was intended to become a two-track station. Above the tunnel north of the Broadway station on the Crosstown Line, a six-track station shell was partially completed. This station would have provided service to the IND Worth Street and the Houston Street Lines. Rapid transit line Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on railway tracks . Some systems use guided rubber tires , magnetic levitation ( maglev ), or monorail . The stations typically have high platforms, without steps inside
16356-738: The damaged equipment was replaced with available spare parts, and normal service resumed on April 21. The 2015–2019 Metropolitan Transportation Authority Capital Plan called for five of the Eighth Avenue Line's stations, along with 28 others, to undergo a complete overhaul as part of the Enhanced Station Initiative . The stations receiving renovations are 34th Street–Penn Station , 72nd Street , 86th Street , Cathedral Parkway–110th Street , and 163rd Street–Amsterdam Avenue . Updates included cellular service, Wi-Fi, USB charging stations, interactive service advisories and maps, improved signage, and improved station lighting. As part of
16530-413: The day and local stops during the night; and the C train at all times except late nights and always makes local stops. The station is the northern terminus for C trains; the next station to the north for A trains is 175th Street . The next station to the south is 163rd Street–Amsterdam Avenue for local trains and 145th Street for express trains. Unlike other express stations in the subway system,
16704-414: The display of the transit network. Often this has the effect of compressing the distance between stations in the outer area of the system, and expanding distances between those close to the center. Some systems assign unique alphanumeric codes to each of their stations to help commuters identify them, which briefly encodes information about the line it is on, and its position on the line. For example, on
16878-460: The early 21st century; in 2007 alone, one of the station's elevators malfunctioned 18 times while passengers were inside. From 2013 to 2016, the IRT station was partially renovated, with the station ceiling and northbound platform tilework replaced with replicas and flooring replaced. After a series of elevator malfunctions in 2017, elected officials began advocating for the replacement of the IRT station's elevators, which were nearly twice as old as
17052-605: The elevator operators at the five stations, but this was reversed after dissent from the Transport Workers' Union. The MTA again suggested reassigning elevator operators to station-cleaner positions in June 2023, prompting local politicians to sue to prevent the operators' reassignments. The IRT station was added to the National Register of Historic Places in 2005. The IRT elevators remained unreliable in
17226-531: The elevators in the station are staffed by elevator attendants, who are also employed at four other deep-level stations in Washington Heights. The elevator attendants are intended to reassure passengers, as the elevators are the only entrance to the platforms, and passengers often wait for the elevators with an attendant. The attendants at the five stations are primarily maintenance and cleaning workers who suffered injuries that made it hard for them to continue doing their original jobs. In July 2003, to reduce costs,
17400-611: The entire metropolitan area is called Metra (short for Met ropolitan Ra il), while its rapid transit system that serves the city is called the "L" . Boston's subway system is known locally as "The T". In Atlanta , the Metropolitan Atlanta Rapid Transit Authority goes by the acronym "MARTA." In the San Francisco Bay Area , residents refer to Bay Area Rapid Transit by its acronym "BART". The New York City Subway
17574-445: The existing underground, surface, and elevated lines operated by the IRT and Brooklyn–Manhattan Transit Corporation (BMT). On December 9, 1924, the New York City Board of Transportation (BOT) gave preliminary approval to the construction of a subway line along Eighth Avenue, running from 207th Street. The BOT announced a list of stations on the new line in February 1928, with an express station at 167th Street; this station would be
17748-408: The express (outer) tracks lower below the local tracks, forming another double-decker tunnel, this time under St. Nicholas Avenue . North of 145th Street , the lower (express) tracks rise into the center, and the three-track IND Concourse Line enters St. Nicholas Avenue below the four-track Eighth Avenue Line. 145th Street is a two-level transfer station, with two island platforms on each level. To
17922-727: The express stations (at Fulton, 14th, 42nd, and 59th Streets) were built with long mezzanines so that passengers could walk the entire length of the mezzanines without having to pay a fare. It was proposed to develop the mezzanines of these four stations with shops, so that they would become retail corridors, similar to the underground mall of the under-construction Rockefeller Center . The new subway required 800 cars and 1,500 staff. In June 1932, The New York Times reported that seven-car express trains would run between 168th and Chambers Streets, while five-car local trains would run between 207th and Chambers Streets. Both express and local trains would run at intervals of four to twelve minutes depending on
18096-552: The express tracks east under Fulton Street to Jay Street–Borough Hall in Brooklyn, was opened for the morning rush hour on February 1, 1933, with the exception of the station at High Street , which opened on June 24, 1933. Initially, only the Fulton Street entrance was open; the Adams Street entrance would open later once its escalators were completed. The Jay–Smith–Ninth Street Line opened on March 20, 1933, extending
18270-421: The express tracks, used by the A train, are on the outside and the local tracks, used by the C train, are on the inside. This is to make it easier for C trains to originate and terminate here, and turn around north of the station to make the southbound trip to Brooklyn. South of this station, the outer express tracks descend to a lower level below the inner local tracks, creating a two-over-two track layout. North of
18444-516: The floor rather than resting on ballast , such as normal railway tracks. An alternate technology, using rubber tires on narrow concrete or steel roll ways , was pioneered on certain lines of the Paris Métro and Mexico City Metro , and the first completely new system to use it was in Montreal , Canada. On most of these networks, additional horizontal wheels are required for guidance, and
18618-434: The four-track IND Sixth Avenue Line . The two-level West Fourth Street–Washington Square station allows easy transfers between the two lines. Just to the south are track connections between the local tracks of each line, not used by current normal service patterns. The Sixth Avenue Line turns east into Houston Street after passing the connections. Canal Street , under Sixth Avenue, is the last normal four-track station on
18792-453: The heat and radiation from an atomic bomb. To become suitable as shelters, the stations would require water-supply facilities, first-aid rooms, and additional bathrooms. However, the program, which required federal funding, was never completed. To increase passenger flow, officials replaced the IND station's pocket-change booths with high turnstiles in 1957, which prompted many complaints from passengers. In Fiscal Year 1958, two elevators at
18966-484: The inner tracks. The transfer between the IRT platforms and the IND platforms has been within fare control since July 1, 1948. The IND station contains elevators, which make it compliant with the Americans with Disabilities Act of 1990 (ADA). While the IRT station can only be reached by elevators, it is not ADA-accessible. The IRT station's interior is listed on the National Register of Historic Places . Planning for
19140-511: The installation of scaffolding, and the NYCTA could only use a chemical solution that was less potent than most chemical-cleaning solutions. By the early 1990s, many homeless people were sheltered within the 168th Street station and the tunnels near it; the city's largest homeless shelter was nearby. The MTA closed one of the station's entrances in March 1991 due to concerns about crime. Although
19314-439: The interconnections between different parts of the system; for example, they show the interchange stations where passengers can transfer between lines. Unlike conventional maps, transit maps are usually not geographically accurate, but emphasize the topological connections among the different stations. The graphic presentation may use straight lines and fixed angles, and often a fixed minimum distance between stations, to simplify
19488-500: The introduction of "R-type" rolling stock , which contained rollsigns with numbered designations for each service. The route to 242nd Street became known as the 1 . All 1 trains became local in 1959, and increased and lengthened service was implemented during peak hours on the 1 train on February 6, 1959. In April 1988, the New York City Transit Authority (NYCTA) unveiled plans to speed up service on
19662-686: The latter of which would have had connections to the IND Crosstown Line and a major junction to the IND Houston Street Line , the IND Utica Avenue Line, and a connection to the Rockaways. In March 1930, public hearings were held by the BOT concerning the construction and planning of this line. At the March 12 hearing, the project's construction was endorsed by east side civic organizations. In June 1930,
19836-412: The line beyond Jay Street–Borough Hall. When the subway opened in 1932, express ( A ) and local ( AA ) trains served the line; expresses did not run during late nights or Sundays. Expresses and late night/Sunday locals were sent south into Brooklyn on February 1, 1933, and, when the IND Concourse Line opened on July 1, 1933, the C was added to the express service, while all locals became CC trains to
20010-423: The line is chained as Line "A", with tracks A1, A3, A4, and A2 from west to east, running from approximately 800 at the south end to 1540 at the north end (measured in hectofeet). The whole line is served at all times by the A train, which runs express except during late nights. The C provides local service south of 168th Street while the A runs express. In addition, the B provides weekday local service and
20184-414: The line. Crossovers in each direction, beyond the station, take C and late night A trains between the local tracks to the north and the express tracks to the south. As the subway turns from Sixth Avenue into Church Street , the southbound local track passes under the express tracks, bringing E trains to the east. At this point, a bellmouth originally intended for the never-built IND Worth Street Line
20358-602: The lines of the Lyon Metro includes a section of rack (cog) railway , while the Carmelit , in Haifa, is an underground funicular . For elevated lines, another alternative is the monorail , which can be built either as straddle-beam monorails or as a suspended monorail . While monorails have never gained wide acceptance outside Japan, there are some such as Chongqing Rail Transit 's monorail lines which are widely used in
20532-399: The longest station along the line at 1,115 feet (340 m), was expected to be a major express station with large platforms, so the platforms were staggered away from each other in order to avoid going under property lines. Additionally, several workers died in cave-ins during construction. In the summer of 1926 the BOT held a public hearing and agreed upon the details of the construction of
20706-557: The main rapid transit system. For instance, the Wenhu Line of the Taipei Metro serves many relatively sparse neighbourhoods and feeds into and complements the high capacity metro lines. Some systems have been built from scratch, others are reclaimed from former commuter rail or suburban tramway systems that have been upgraded, and often supplemented with an underground or elevated downtown section. Ground-level alignments with
20880-418: The network map "readable" by illiterate people, this system has since become an "icon" of the system. Compared to other modes of transport, rapid transit has a good safety record, with few accidents. Rail transport is subject to strict safety regulations , with requirements for procedure and maintenance to minimize risk. Head-on collisions are rare due to use of double track, and low operating speeds reduce
21054-566: The new Eighth Avenue subway via St. Nicholas Avenue provided an alternative route. In particular, the IND's 168th Street station provided easy access to the Columbia University Irving Medical Center , as trains from 168th Street could reach Lower Manhattan within a half hour. When the IND station opened, it was connected to the IRT station at the same intersection via a passageway. This corridor originally required payment of an additional fare, but it
21228-571: The next month. The city received bids for the elevator cabs that December and awarded the contract to the Otis Elevator Company . In Fiscal Year 1923, work began on the installation of a new entrance with elevators on the west side of Broadway to increase the capacity of the station. The following fiscal year, the IRT reported that work to construct new entrances to the station was 87 percent complete. The two elevators entered service on June 26, 1924. The city government took over
21402-402: The next vehicle will arrive, and expected travel times. The standardized GTFS data format for transit information allows many third-party software developers to produce web and smartphone app programs which give passengers customized updates regarding specific transit lines and stations of interest. Mexico City Metro uses a unique pictogram for each station. Originally intended to help make
21576-486: The north end of Fort Washington Avenue , which it follows to roughly 175th Street before turning southeast under private property. The small 174th Street Yard lies under Broadway, with two tracks exiting to the south under that roadway. When the George Washington Bridge was designed in the 1920s, provisions were made for a lower deck that would carry these two tracks north from the yard and across
21750-563: The northern terminus of local service. Most of the Eighth Avenue Line was dug using a cheap cut-and-cover method. In September 1928, the Woodcrest Construction Company received a $ 375,014 contract to construct the 155th Street , 163rd Street , and 168th Street stations on the new line. A preview event for the new subway was hosted on September 8, 1932, two days before the official opening. The Eighth Avenue Line station opened on September 10, 1932, as part of
21924-441: The northwest corner. An exit-only turnstile in the middle of the mezzanine, near the corridor leading to the IRT platforms, leads to a staircase going up to north end of Mitchell Square Park on the south side of West 168th Street between Broadway and Saint Nicholas Avenue. The passageway leading to the IRT elevators is just beyond the full-time fare control area. There are two exit stairs past this part-time fare control area, near
22098-958: The occurrence and severity of rear-end collisions and derailments . Fire is more of a danger underground, such as the King's Cross fire in London in November 1987, which killed 31 people. Systems are generally built to allow evacuation of trains at many places throughout the system. High platforms , usually over 1 meter / 3 feet, are a safety risk, as people falling onto the tracks have trouble climbing back. Platform screen doors are used on some systems to eliminate this danger. Rapid transit facilities are public spaces and may suffer from security problems: petty crimes , such as pickpocketing and baggage theft, and more serious violent crimes , as well as sexual assaults on tightly packed trains and platforms. Security measures include video surveillance , security guards , and conductors . In some countries
22272-447: The only public connection between the platforms and fare control being made via elevator. Close to street level is an upper mezzanine level with an unstaffed fare control area. Four elevators lead down to a lower mezzanine below the IRT platforms. At the upper mezzanine, a closed passageway exists behind the elevator bank. The IRT's 168th Street station was one of the few on the original IRT line to contain elevators. The IRT station
22446-603: The only two North American systems that are primarily called "subways". In most of Southeast Asia and in Taiwan , rapid transit systems are primarily known by the acronym MRT . The meaning varies from one country to another. In Indonesia , the acronym stands for Moda Raya Terpadu or Integrated Mass [Transit] Mode in English. In the Philippines , it stands for Metro Rail Transit . Two underground lines use
22620-474: The opening of the Sixth Avenue Line on December 15, 1940, ran as a rush-hour only local service starting at 168th Street–Washington Heights. The "B" designation was originally intended to designate express trains originating in Washington Heights and going to Midtown Manhattan on the Sixth Avenue Line. The AA was resurrected when the BB was created, running outside rush hours. The AA was renamed
22794-587: The outset. Budapest , Chicago , Glasgow , Boston and New York City all converted or purpose-designed and built electric rail services. Advancements in technology have allowed new automated services. Hybrid solutions have also evolved, such as tram-train and premetro , which incorporate some of the features of rapid transit systems. In response to cost, engineering considerations and topological challenges some cities have opted to construct tram systems, particularly those in Australia, where density in cities
22968-431: The plan. The accessibility project was to be funded by congestion pricing in New York City , but it was postponed in June 2024 after the implementation of congestion pricing was delayed. A slightly sloped corridor within fare control leads between the IRT and IND mezzanines. A full length mezzanine extends above the IND platforms. Elevators from the mezzanine to the street, and to each IND platform, make that portion of
23142-458: The platform extension opened for stations from 103rd Street to Dyckman Street , including this station but excluding 125th Street . Plans for a second subway line with a station at 168th Street and Broadway date as far back as 1914. That year, engineer Reginald Pelham Bolton proposed a short extension of the elevated IRT Ninth Avenue Line to Riverside Drive , with an intermediate station at 168th Street and Broadway to relieve congestion at
23316-490: The platform extension. The southbound platform was not lengthened. Six-car local trains began operating in October 1910, and ten-car express trains began running on the West Side Line on January 24, 1911. Subsequently, the station could accommodate six-car local trains, but ten-car trains could not open some of their doors. Public Service Commission employees began preparing plans for an additional elevator at
23490-488: The platform level. At the portals between the original vault and the much lower ceilings of the platform extensions, there is a wide arch over the tracks flanked by narrow arches over each platform. These transitions are clad with tan brick. The arch over the tracks has a volute with a laurel wreath. Between the arches, the lower portions of the walls are clad in gray marble. The walls of the platform extensions have white ceramic tiles with mosaic friezes as well as plaques with
23664-496: The platforms were lengthened at Spring Street and Canal Street to 660 feet (200 m) to allow E trains to run eleven-car trains. The E began running eleven-car trains during rush hours on September 8, 1953. The extra train car increased the total carrying capacity by 4,000 passengers. The lengthening project cost $ 400,000. Southbound E trains began stopping at the lower level of the 42nd Street station during rush hours on March 23, 1970, to reduce delays by relieving congestion on
23838-435: The project had been delayed by 20 months due to changes in the project's scope; the overpass and platform walls had yet to be restored. The renovation was completed in 1990 at a cost of $ 2.5 million. The project included relocating pipes and ducts, retiling the lower portions of the walls, and removing dirt from the vaulted ceiling. The NYCTA's director of architecture had wanted to clean the ceiling, but this would have required
24012-908: The rapid transit system varies greatly between cities, with several transport strategies. Some systems may extend only to the limits of the inner city, or to its inner ring of suburbs with trains making frequent station stops. The outer suburbs may then be reached by a separate commuter rail network where more widely spaced stations allow higher speeds. In some cases the differences between urban rapid transit and suburban systems are not clear. Rapid transit systems may be supplemented by other systems such as trolleybuses , regular buses , trams , or commuter rail. This combination of transit modes serves to offset certain limitations of rapid transit such as limited stops and long walking distances between outside access points. Bus or tram feeder systems transport people to rapid transit stops. Each rapid transit system consists of one or more lines , or circuits. Each line
24186-474: The renovations, 72nd Street was closed from May 7, 2018 to October 4, 2018, and 86th Street was closed from June 4, 2018 to October 26, 2018. In addition, the Cathedral Parkway–110th Street station was closed from April 9, 2018 to the week of September 2–4, 2018, and 163rd Street was closed from March 12, 2018 to September 27, 2018. The IND Worth Street Line was a proposed major expansion of
24360-542: The rubber tires. However, they have higher maintenance costs and are less energy efficient. They also lose traction when weather conditions are wet or icy, preventing above-ground use of the Montréal Metro and limiting it on the Sapporo Municipal Subway, but not rubber-tired systems in other cities. Some cities with steep hills incorporate mountain railway technologies in their metros. One of
24534-425: The south, the Concourse Line tracks rise and merge with the Eighth Avenue Line, carrying the B onto the local tracks and the D onto the express tracks. The resulting four-track line continues south under St. Nicholas Avenue and Eighth Avenue (Frederick Douglass Boulevard), which becomes Central Park West at 110th Street . Most of the line under Central Park West is built on two levels with both local tracks to
24708-458: The southbound express track at this station before crossing over to the local one afterwards. Both outer track walls have a maroon trim line with a black border and small "168" tile captions below them in white numbering on a black border. The maroon trim line was part of a color-coded tile system used throughout the IND. The tile colors were designed to facilitate navigation for travelers going away from Lower Manhattan . Because 168th Street
24882-426: The southwest corner of Broadway and 168th Street, which face north and south. The southernmost portion of the mezzanine, which is outside fare control, is closed. It features one passage on the east side of the IND station with two exits to the southeastern corner of 167th Street and St. Nicholas Avenue and a passage on the west side of the IND station with two exits to Mitchel Square Park. The closed mezzanine area
25056-418: The station ADA-accessible. The full-time fare control area is at the center of the mezzanine, and has a turnstile bank, token booth, and one staircase and one elevator going up to the southeast corner of West 168th Street and Saint Nicholas Avenue. The part-time side at the north end of the mezzanine has HEET turnstiles and three staircases, two to the southwest corner of Broadway and 169th Street and one to
25230-494: The station in 1919. The city government authorized the construction of additional elevators at the station in February 1922; there were to be four new shafts on the west side of Broadway, and elevator cabs were to be installed in two of the shafts. The city began receiving bids for the elevator shafts in April 1922, and they also awarded a contract for a new station entrance to Holbrook, Cabot & Rollins Corporation for $ 283,000
25404-483: The station in March 1905; this caused a fire that weakened the tunnel's roof, which then collapsed and killed a firefighter. The damage caused by the crash delayed the station's completion by several months. Although the Fort George tunnel was nearly completed by January 1906, elevators had not been installed at the 168th and 181st Street stations. The West Side Branch was extended northward from 157th Street to
25578-490: The station's platforms. On August 28, 1977, late night AA service was eliminated. The A began making local stops in Manhattan during late nights, when the AA was not running. On May 6, 1985, the IND practice of using double letters to indicate local service was discontinued. The AA was renamed the K and rush hour CC service was renamed C. This change was not officially reflected in schedules until May 24, 1987. On December 10, 1988,
25752-401: The station, the inner local tracks continue north underneath Broadway to the 174th Street Yard , while the outer express tracks turn sharply under Fort Washington Avenue before continuing for four stops before ending at Inwood–207th Street . During the night, the A train makes local stops, using the northbound local track at this station before crossing over to the express one afterwards and
25926-506: The street south of Eighth Street), and to provide access to the Holland Tunnel . The construction of the extension was completed in 1930. The city condemned entire lots, displacing 10,000 people, to build the extension and used leftover land for parks. The stations on the line were built with 600 feet (180 m) long platforms, but they had provisions to lengthen them to 660 feet (200 m) to accommodate eleven-car trains. Four of
26100-411: The street was not affected by the construction. $ 9,631,760 was awarded to 161 property owners whose property had been taken. 168,888 square feet of land had to be acquired to widen Church Street between Park Place and Canal Street. In 1926 construction began on the extension of Sixth Avenue south from Carmine Street to Canal Street, to allow for the construction of the Eighth Avenue Line (which runs under
26274-663: The suburbs, allowing a higher service frequency in the center. This arrangement is used by many systems, such as the Copenhagen Metro , the Milan Metro , the Oslo Metro , the Istanbul Metro and the New York City Subway . Alternatively, there may be a single central terminal (often shared with the central railway station), or multiple interchange stations between lines in the city center, for instance in
26448-490: The subway and maintain a 50-year operating lease from the opening of the line. In 1901, the firm of Heins & LaFarge was hired to design the underground stations. Belmont incorporated the Interborough Rapid Transit Company (IRT) in April 1902 to operate the subway. The 168th Street station was constructed as part of the IRT's West Side Line (now the Broadway–Seventh Avenue Line ) from 133rd Street to
26622-408: The subway line under Church Street . As part of the construction of the line, Church Street was widened from being 40 feet (12 m) wide to being 90 feet (27 m) wide to accommodate the subway underneath and was connected with a southern diagonal extension of Sixth Avenue, which was 100 feet (30 m). Had the street not been widened the construction would have cost an additional $ 7 million for
26796-499: The subway system, 50 more stations will become ADA-accessible during the MTA's 2020–2024 Capital Program, allowing all riders to have an accessible station within two stops in either direction. To meet this goal, one station in the Washington Heights/ Inwood area will have to be made accessible on the IRT Broadway–Seventh Avenue Line. The 168th Street station was ultimately selected to be retrofitted as part of
26970-714: The term subway . In Thailand , it stands for Metropolitan Rapid Transit , previously using the Mass Rapid Transit name. Outside of Southeast Asia, Kaohsiung and Taoyuan, Taiwan , have their own MRT systems which stands for Mass Rapid Transit , as with Singapore and Malaysia . In general rapid transit is a synonym for "metro" type transit, though sometimes rapid transit is defined to include "metro", commuter trains and grade separated light rail . Also high-capacity bus-based transit systems can have features similar to "metro" systems. The opening of London's steam-hauled Metropolitan Railway in 1863 marked
27144-530: The term Subway into railway terminology. Both railways, alongside others, were eventually merged into London Underground . The 1893 Liverpool Overhead Railway was designed to use electric traction from the outset. The technology quickly spread to other cities in Europe , the United States, Argentina, and Canada, with some railways being converted from steam and others being designed to be electric from
27318-479: The time of day. The new IND subway line also used a five-color pattern of tiles to facilitate navigation for travelers going away from Manhattan; the colors of the tiles changed at each express station. The majority of the Eighth Avenue Line, from Chambers Street north to 207th Street , was opened to the public just after midnight on September 10, 1932, after three days of operation on a normal schedule but without passengers. The Cranberry Street Tunnel , extending
27492-511: The trains, requiring custom-made trains in order to minimize gaps between train and platform. They are typically integrated with other public transport and often operated by the same public transport authorities . Some rapid transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines. The world's first rapid transit system was the partially underground Metropolitan Railway which opened in 1863 using steam locomotives , and now forms part of
27666-581: The two, located between High Street and Jay Street–MetroTech . Both the A and C trains continue along the Fulton Street Line. As early as March 1918, soon after the BMT Broadway Line opened to Times Square–42nd Street , plans were being considered for an extension of that line beyond the stubs at 57th Street–Seventh Avenue to the Upper West Side and Washington Heights via Central Park West (Eighth Avenue). On August 3, 1923,
27840-601: The use of communications-based train control : the minimum headway can reach 90 seconds, but many systems typically use 120 seconds to allow for recovery from delays. Typical capacity lines allow 1,200 people per train, giving 36,000 passengers per hour per direction . However, much higher capacities are attained in East Asia with ranges of 75,000 to 85,000 people per hour achieved by MTR Corporation 's urban lines in Hong Kong. Rapid transit topologies are determined by
28014-539: The walls contain tan brick. Tile name tablets are placed above the frieze at regular intervals, with white letters on a dark-green background surrounded by floral designs. These tablets contain the text "168th Street". The center of the vault ceiling has multicolored terracotta medallions at regular intervals; these formerly held lighting fixtures. Where the elevator shafts are positioned, the station widens to 73 feet (22 m). The station's platform extensions have ceilings that are 10 to 12 feet (3.0 to 3.7 m) above
28188-510: The west and only local stations. The two northbound tracks are above the two southbound tracks. Approaching 59th Street–Columbus Circle , where Central Park West becomes Eighth Avenue, the subway again spreads out into a single four-track level. A flying junction south of 59th Street takes B and D trains east under 53rd Street , merging with two tracks from 57th Street to become the four-track IND Sixth Avenue Line . The two-track IND Queens Boulevard Line , also in 53rd Street, curves south into
28362-597: The words "168th Street". The walls are divided every 15 feet (4.6 m) by multicolored tile pilasters that are 16 inches (410 mm) wide. There are two tile panels with the number "168" in each panel. Columns near the platform edge, clad with white tile, support the jack-arched concrete station roof. The 168th Street station is an express station on the IND Eighth Avenue Line that has four tracks and two island platforms . The A train stops here at all times, making express stops during
28536-488: The yard tracks at 168th Street . The local/express split begins here, with the local tracks coming from the yard and the express tracks coming from Inwood. Contrary to standard practice, the two local tracks are in the center and the two express tracks are on the outside. Except during late nights, the local service ( C ) ends at 168th Street, reversing direction on the yard tracks; the A runs to 207th Street at all times, express except during late nights. South of 168th Street,
28710-559: Was Singapore's Mass Rapid Transit (MRT) system, which launched its first underground mobile phone network using AMPS in 1989. Many metro systems, such as the Hong Kong Mass Transit Railway (MTR) and the Berlin U-Bahn, provide mobile data connections in their tunnels for various network operators. The technology used for public, mass rapid transit has undergone significant changes in the years since
28884-435: Was built as an express and terminal station for the Independent Subway System (IND) and opened on September 10, 1932, as part of the IND's first segment. The IRT station has two side platforms and two tracks. The IND station has two island platforms and four tracks, although the track configuration is reversed from most New York City Subway express stations, with express trains using the outer tracks and local trains using
29058-899: Was developed further. Other Central European countries also have metro lines, for example in the cities of Budapest (Hungary), Prague (Czech Republic) and Warsaw (Poland). In Eastern Europe , metro systems are in operation in Minsk (Belarus), Kyiv (Ukraine), Riga (Latvia), Vilnius (Lithuania) and Moscow (Russia). In Southeastern European countries, there are metro systems in Athens and Thessaloniki (Greece), Belgrade (Serbia), Sofia (Bulgaria) and Istanbul (Turkey). In Northern Europe , rapid transit systems exist in Copenhagen (Denmark), Oslo (Norway), Stockholm (Sweden) and Helsinki (Finland). Various terms are used for rapid transit systems around North America . The term metro
29232-481: Was extended to 168th Street to allow A trains to run express. Beginning April 30, 1995, C service was extended to 168th Street during middays as construction on the Manhattan Bridge cut B service from Manhattan. On November 11, 1995, midday service was cut back to 145th Street after B service to 168th Street was restored. The change was made to reduce crowding on the C and to reduce passenger confusion about
29406-433: Was held at St. Nicholas Avenue and 123rd Street on March 14, 1925. Most of the Eighth Avenue Line was dug using a cheap cut-and-cover method, where the street above was excavated. Still, the construction of the line was difficult, as it had to go under or over several subway lines. At 59th Street–Columbus Circle , workers had to be careful to not disrupt the existing IRT Broadway–Seventh Avenue Line overhead. 42nd Street ,
29580-534: Was kept only during rush hours to provide local service south past 59th Street. Additionally the C became a rush hour-only service, replaced by a full-time D over the express tracks between the Concourse and Sixth Avenue Lines. This created the pattern that has remained to this day, with five services during normal hours: the A express, B part-time local via Sixth Avenue (then BB), C local (then AA and CC), D express via Sixth Avenue, and E local from Queens. In 1953,
29754-702: Was low and suburbs tended to spread out . Since the 1970s, the viability of underground train systems in Australian cities, particularly Sydney and Melbourne , has been reconsidered and proposed as a solution to over-capacity. Melbourne had tunnels and stations developed in the 1970s and opened in 1980. The first line of the Sydney Metro was opened in 2019. Since the 1960s, many new systems have been introduced in Europe , Asia and Latin America . In
29928-415: Was originally 320 feet (98 m) long but was extended to fit 514-foot-long (157 m) trains in 1948. Near the north end of the station, there are four elevators adjacent to the southbound platform, which lead to the fare control level. These elevators are accessed via a concourse several steps above the southbound platform. The lower sections of the concourse walls are clad with white tile, topped by
30102-602: Was placed inside fare control on July 1, 1948. On December 28, 1950, the New York City Board of Transportation issued a report concerning the construction of bomb shelters in the subway system. Five deep stations in Washington Heights, including the IRT's 168th Street station, were considered to be ideal for being used as bomb-proof shelters. The program was expected to cost $ 104 million (equivalent to $ 1,317 million in 2023). These shelters were expected to provide limited protection against conventional bombs, while providing protection against shock waves and air blast, as well as from
30276-399: Was spent on building additional entrances and exits. It was anticipated that these improvements would increase capacity by 25 percent. The northbound platform at the 168th Street station was extended 179 feet (55 m) to the south. The arched ceiling adjacent to the platform extension was replaced with a flat roof made of steel beams, since the arch's structural integrity was compromised by
