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.
85-403: The White Plains Road Line is a rapid transit line of the A Division of the New York City Subway serving the central Bronx . It is mostly elevated and served both subway and elevated trains until 1952. The original part of the line, the part opened as part of the first subway was called the West Farms Division, and the extension north to 241st Street as part of the Dual Contracts
170-425: 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
255-454: 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
340-651: 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
425-563: A connection running from the Third Avenue local tracks at Third Avenue and 149th Street to Westchester Avenue and Eagle Avenue. Once the connection to the IRT Lenox Avenue Line opened on July 10, 1905, trains from the newly opened IRT subway ran via the line. Elevated service via this connection was resumed on October 1, 1907 when Second Avenue locals were extended to Freeman Street during rush hours. On October 28, 1910,
510-583: 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
595-405: 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
680-418: A large number of factors, including geographical barriers, existing or expected travel patterns, construction costs, politics, and historical constraints. 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
765-652: 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 ,
850-452: 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
935-615: 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

#17327720157901020-523: A rapid transit setting. John B. McDonald John B. McDonald (November 7, 1844 – March 17, 1911) was an Irish -born contractor who is best known for overseeing construction of New York City's first subway line from 1900 to 1904. John B. McDonald was born on November 7, 1844, in Cork, Ireland to Bartholomew McDonald, a contractor and cellar digger. At a young age, he came to New York City and attended public schools. His father became served as
1105-481: A representative in the New York City Board of Aldermen . From 1900 to 1904, McDonald oversaw the construction of the first New York City Subway line. McDonald won the job with a $ 35 million bid in 1900, but he did not have the capital necessary to post the surety bonds the city required, so he turned to the banker August Belmont Jr. , for financial backing. After that, McDonald effectively worked for
1190-565: 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
1275-608: 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
1360-801: 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
1445-608: 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
1530-506: 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
1615-416: 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
1700-555: 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
1785-412: 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
SECTION 20
#17327720157901870-748: 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
1955-627: The Dublin Area Rapid Transit is despite the name considered a commuter rail due to usage of mainline railways. 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
2040-752: The Hudson and Manhattan Railroad K-series cars from 1958, the New York City Subway R38 and R42 cars from the late-1960s, and the Nagoya Municipal Subway 3000 series , Osaka Municipal Subway 10 series and MTR M-Train EMUs from the 1970s, were generally only made possible largely due to the relatively generous loading gauges of these systems and also adequate open-air sections to dissipate hot air from these air conditioning units. Especially in some rapid transit systems such as
2125-429: The London Underground . In 1868, New York opened the elevated West Side and Yonkers Patent Railway , initially a cable-hauled line using stationary steam engines . As of 2021 , China has the largest number of rapid transit systems in the world – 40 in number, running on over 4,500 km (2,800 mi) of track – and was responsible for most of the world's rapid-transit expansion in
2210-740: 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
2295-578: 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
2380-589: 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
2465-685: The Singapore MRT , Changi Airport MRT station has the alphanumeric code CG2, indicating its position as the 2nd station on the Changi Airport branch of the East West Line. 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
2550-749: The West Farms Yard , also gone. The express track ends north of Third Avenue–149th Street , and from there to the end the line has two tracks. Formerly in that area there was a connection just to the north to the local tracks of the IRT Third Avenue Line , and a connection to the south, bypassing 149th Street on the Third Avenue Line. Just past those former connections, the White Plains Road Line goes underground. Just after 149th Street–Grand Concourse ,
2635-450: 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

2720-409: 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
2805-432: The 15 world largest subway systems suggested a universal shape composed of a dense core with branches radiating from it. 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
2890-488: The 1995 Tokyo subway sarin gas attack and the 2005 " 7/7 " terrorist bombings on the London Underground. Some rapid transport trains have extra features such as wall sockets, cellular reception, typically using a leaky feeder in tunnels and DAS antennas in stations, as well as Wi-Fi connectivity. The first metro system in the world to enable full mobile phone reception in underground stations and tunnels
2975-621: The 2010s. The world's longest single-operator rapid transit system by route length is the Shanghai Metro . The world's largest single rapid transit service provider by number of stations (472 stations in total) is the New York City Subway . The busiest rapid transit systems in the world by annual ridership are the Shanghai Metro, Tokyo subway system , Seoul Metro and the Moscow Metro . The term Metro
3060-532: The 21st century, most new expansions and systems are located in Asia, with China becoming the world's leader in metro expansion, operating some of the largest and busiest systems while possessing almost 60 cities that are operating, constructing or planning a rapid transit system . Rapid transit is used for local transport in cities , agglomerations , and metropolitan areas to transport large numbers of people often short distances at high frequency . The extent of
3145-407: The 239th Street Yard. Additional time was required to modify the structure to avoid a grade crossing at the entrance to the yard. A 1929 proposal included a spur off the line that would have run from Van Nest to Baychester . The spur was to begin near Garfield Street as an elevated line then run underground beneath Morris Park Avenue and Wilson Avenue, finally terminating at Boston Road , where it
3230-434: The 5 Lexington Avenue Thru-Express. The Dyre Avenue Line was connected directly to the White Plains Road Line north of East 180th Street for $ 3 million and through service began on May 6, 1957. Night service continued to be operated by a shuttle. Through service was operated by Seventh Avenue express trains between 5:30 AM and 8:30 PM. Between 8:30 and 1:15 shuttle trains operated from East 180th Street to Dyre Avenue, and in
3315-524: The Bronx communities of Williamsbridge and Wakefield with access to rapid transit service. Service on the new portion of the line was operated as a four-car shuttle from 177th Street due to the power conditions at the time. Service was extended to East 238th Street on March 31, 1917. The part of the line from the S-curve north of West Farms Square—East Tremont Avenue station to the terminal at 241st Street
3400-860: The City and two separate private companies (the Interborough Rapid Transit Company and the Brooklyn Rapid Transit Company ), all working together to make the construction of the Dual Contracts possible. The Dual Contracts promised the construction of several lines in the Bronx. As part of Contract 3, the IRT agreed to extend the existing West Farms Division from 179th Street to 241st Street as an elevated line along White Plains Road. Intervale Avenue station opened on April 30, 1910 as an in-fill station. It
3485-638: The IRT White Plains Road Line began on April 23, 1953 with alternate 5 trains using the middle track between East 180th Street and 149th Street during the weekday rush in the peak direction. These trains skipped all stops between East 180th Street and Third Avenue–149th Street. Starting on October 2, 1953, 5 trains began running express between East 180th Street and Gun Hill Road using the middle track in order to encourage passengers who changed at Gun Hill Road for Third Avenue Elevated service to stay on subway trains. These trains were signed as

3570-637: The IRT White Plains Road Line: The IRT White Plains Road Line begins at the Wakefield–241st Street terminal , with two tracks, one island platform, and two closed side platforms. Crossovers just south of the station take trains to the correct tracks and a center express track comes out of those crossovers. Between Wakefield–241st Street and Nereid Avenue , a connection comes in from the 239th Street Yard . Just north of Gun Hill Road ,
3655-545: The RTC's proposed extension of the line through Bronx Park via a new elevated structure. The RTC abandoned its proposal at a public hearing the following day. The initial segment of the IRT White Plains Road Line opened on November 26, 1904 between East 180th Street and Jackson Avenue. Initially, trains on the line were served by elevated trains from the IRT Second Avenue Line and the IRT Third Avenue Line , with
3740-478: 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
3825-525: The center track to end its run, and rush hour 5 trains in the peak direction change to the express track here. On the west side of this junction is the East 180th Street Yard while the Unionport Yard is to the east. The now-gone three-track Bronx Park Spur merged from the west after East 180th Street with one track into each of the mainline tracks. Just after this on the east side was a connection to
3910-446: The company that Belmont formed, the Interborough Rapid Transit Company , but McDonald was credited with being an extremely able builder. The initial segment from City Hall to Grand Central , across 42nd Street to Times Square , and up Broadway to 145th Street —was completed on schedule on October 27, 1904. It was a remarkable achievement given the complexity and novelty of the project and periodic labor turmoil. In 1905, McDonald
3995-414: 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
4080-546: The early morning hours no trains operated over the line. In 1986, the New York City Transit Authority launched a study to determine whether to close 79 stations on 11 routes, including the White Plains Road Line north of East 180th Street, due to low ridership and high repair costs. Numerous figures, including New York City Council member Carol Greitzer , criticized the plans. Due to rehabilitation of East 180th Street and signal replacements along
4165-611: 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
4250-516: 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
4335-485: The gradual curtailment of elevated service on the IRT Third Avenue Line. The cutoff was removed in 1950. On December 13, 1920, the final portion of the line opened, extending the line from its previous terminal at 238th Street to the line's permanent terminus at 241st Street. This portion of the line had its opening delayed, owing to construction on the line between the two stations for the construction of

#17327720157904420-481: The improvement plan was the elimination of the at-grade junction north of the West Farms Square station, which was a major bottleneck, by closing the spur to 180th Street–Bronx Park. To make up for the loss of service, an escalator and new stairway would be added at the West Farms Square station at 178th Street and Boston Road. The spur to 180th Street—Bronx Park closed on August 4, 1952. Express service on
4505-439: 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
4590-676: The line, rush hour peak direction 5 express service was suspended from March 29 to September 3, 2010. PM northbound express service was suspended again on March 28, 2011 to allow for the second phase of the signal replacement project. Normal service was restored on August 8, 2011. Bx41 Select Bus Service Bx41 Select Bus Service Rapid transit 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

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
4760-557: 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
4845-483: The middle third track. New signaling, including the installation of block signals, was to be installed on the local tracks, in addition to the installation of signals on the express track at the cost of $ 3.5 million. In addition, it was announced that a flyover to the Dyre Avenue Line would be built, allowing for through-service, and eliminating the need to transfer at East 180th Street. The final key element to

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
5015-516: The new 180th Street station, known as Zoological Park station, opened as the new terminal of the West Farms Division of the subway, replacing the temporary station at 180th Street, which was later abandoned. The Dual Contracts , which were signed on March 19, 1913, were contracts for the construction, rehabilitation, and operation of rapid transit lines in the City of New York . The contracts were "dual" in that they were signed between

The line went to a lower level of Gun Hill Road and then turned west. The IRT Dyre Avenue Line merges to the local tracks just north of East 180th Street , and then crossovers allow those trains to reach the express tracks. The 5 late-night Dyre Avenue Shuttle uses

#17327720157905270-958: 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
5355-603: 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
5440-587: 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
5525-503: The platforms extensions at the stations on the line from Jackson Avenue to 177th Street opened. The platforms were lengthened to 514 feet (157 m) to allow full ten-car express trains to platform. Previously the stations could only platform six-car local trains. On March 1, 1951, the Board of Transportation announced a plan to implement express service along the White Plains Road Line between 241st Street and Third Avenue–149th Street using
5610-908: 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
5695-542: 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
5780-568: The speeding up of the line's construction between Brook Avenue and Bronx Park to have it complete within four or five months, and the commission's permission to construct a connection along Brook Avenue between Westchester Avenue and Third Avenue, where a track connection would be provided to the Third Avenue Elevated . If the proposal was approved, a portion of the line could be open by the fall. On January 11, 1905, Assemblyman William J. Ellis introduced legislation that would block
5865-663: 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
5950-829: The subway, McDonald had made a name for himself on other rail projects, including a challenging project in the early 1890s tunneling underneath downtown Baltimore to bring the Baltimore & Ohio Railroad to the Baltimore Harbor. The so-called Howard Street Tunnel is still in use by freight trains. He also worked on the San Francisco Harbor , the Canadian Pacific Railway , the Entre Ríos Railway in South America,
6035-646: 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
6120-530: 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
6205-611: The tracks split off and the two currently used by the 5 train turn south to merge with the local tracks of the IRT Jerome Avenue Line . The other tracks, currently used by the 2 train, pass under the Harlem River via the 149th Street Tunnel and end at the at-grade 142nd Street Junction, connecting to the IRT Lenox Avenue Line . The first contract for the construction of a subway in New York, Contract 1 ,
6290-511: 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
6375-601: 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
6460-559: 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
6545-548: Was built as a part of the Dual Contracts . On July 1, 1917, a new connection between the White Plains Road Line and the Third Avenue el express tracks opened as part of the Dual Contracts expansion of the Third Avenue Line, and since it ran via Bergen Avenue and bypassed the 149th Street station, it was called the Bergen Avenue cutoff or bypass. The Bergen Avenue cutoff was abandoned on November 5, 1946, as part of
6630-485: Was called the White Plains Road Line. Eventually, however, the two parts came to be known as the White Plains Road Line. It is currently being used by the 2 at all times and the 5 at all times except late nights. During rush hours in the peak direction, the 5 runs express between East 180th Street and Third Avenue–149th Street . During late nights, the 5 runs as a shuttle between Eastchester–Dyre Avenue and East 180th Street. The following services use part or all of
6715-899: 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
6800-551: Was executed on February 21, 1900, between the Board of Rapid Transit Railroad Commissioners and the Rapid Transit Construction Company, organized by John B. McDonald and funded by August Belmont , for the construction of the subway and a 50-year operating lease from the opening of the line. Contract 1 called for the construction of a line from City Hall north to Kingsbridge and a branch under Lenox Avenue and to Bronx Park . In August 1902, it
6885-538: Was hired away by a rival transit mogul, Thomas Fortune Ryan , who proposed to build a competing subway line. Ryan agreed to pay McDonald $ 250,000 in two installments up front plus $ 50,000 a year for five years not to be involved in construction for any company other than the Metropolitan Street Railway Company, Ryan's company. By the time McDonald testified to the arrangement in 1907, Ryan and Belmont had merged their companies. Before
6970-702: 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
7055-479: Was reported that the Rapid Transit Commission (RTC) had decided to spend an additional $ 400,000 to have the elevated portion of the line in the Bronx be constructed with three tracks instead of two. On May 29, 1903, a proposal by August Belmont to speed up the opening of the subway line to Bronx Park by operating it with elevated trains was presented at a meeting of the RTC. The proposal required
7140-467: Was the first station in the Bronx with escalators. The station was built at the cost of $ 100,000, and it was paid with private capital. Portions of the White Plains Road Line were opened at different times, and they opened once construction finished on a segment, as opposed to waiting for the completion of the entire line. The first segment opened on March 3, 1917, from East 177th Street–East Tremont Avenue to East 219th Street–White Plains Road , providing
7225-555: Was to connect to the formerly proposed Concourse Line extension . This proposal was never carried out, however the IRT acquired the former New York, Westchester and Boston Railway right-of-way to create the IRT Dyre Avenue Line instead. The New York State Transit Commission announced plans to extend the southbound platforms at seven stations on the line from Jackson Avenue to 177th Street to accommodate ten-car trains for $ 81,900 on August 8, 1934. On June 13, 1949,
