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.
107-457: The IND Rockaway Line is a rapid transit line of the IND Division of the New York City Subway , operating in Queens . It branches from the IND Fulton Street Line at Rockaway Boulevard , extending over the Jamaica Bay , into the Rockaways . At its southern end in the Rockaways, the line has two branches: one traveling east to Far Rockaway–Mott Avenue and one traveling west to Rockaway Park–Beach 116th Street . The A train serves
214-425: 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
321-454: 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
428-651: 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
535-583: 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
642-405: 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
749-400: A lack of available materials. Therefore, the railroad asked Green Bus Lines to provide service for passengers stranded at Broad Channel and The Raunt . Another took place at The Raunt on December 15, 1948, delaying trains between nine and nineteen minutes during the morning rush hour. 300 feet (91 m) of the trestle was destroyed during a July 4, 1949, fire, and morning rush hour service
856-418: 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
963-652: 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 ,
1070-452: 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
1177-615: 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

#17327763484781284-584: A rapid transit setting. Rockaway Park Shuttle The Rockaway Park Shuttle is a New York City Subway shuttle train that operates in Queens . It connects with the A train at Broad Channel station and is the latest iteration of the Rockaway Shuttle services that have been running on the Rockaway peninsula since 1956. This shuttle train provides service to the western part of
1391-873: A result of the initial plan to make A service local in Manhattan and Brooklyn (before it was amended to reroute the A via Sixth Avenue), H service would be expanded. This change was necessitated because all Central Park West express service would operate via Sixth Avenue, leaving no express service along Eighth Avenue south of 59th Street–Columbus Circle ; daytime service would operate between 34th Street–Penn Station and either Ozone Park–Lefferts Boulevard or Far Rockaway–Mott Avenue in Queens, making express stops in Manhattan and Brooklyn and local stops in Queens. Additional rush hour trains to and from Rockaway Park–Beach 116th Street would have provided limited service. Late night service would initially be replaced by A trains before
1498-757: A single storage track. The Far Rockaway Branch, tracks F3A and F4A, goes east via an elevated structure over the Rockaway Freeway and terminates at a two-track terminal of Far Rockaway–Mott Avenue. Most of the Rockaway Line dates back to the 1880s when it was operated as the New York, Woodhaven and Rockaway Railroad; the Far Rockaway station had been in operation since 1869 as part of the South Side Railroad of Long Island. In 1892,
1605-565: 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
1712-608: 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
1819-413: A train every 24 minutes. The line was built to handle 100,000 daily passengers but was only carrying 6,000. A new station at Far Rockaway–Mott Avenue opened on January 16, 1958, completing the Rockaway Line. The completion of the new terminal was delayed due to the slow delivery of steel. The line charged a double fare south of Howard Beach which entailed the deposit of two tokens for those entering along
1926-801: 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
2033-608: 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
2140-506: 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
2247-416: 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

#17327763484782354-606: Is provided by a limited number of A trains). The segment of the line between Howard Beach and the Rockaway Peninsula suffered serious damage during Hurricane Sandy and was out of service for several months. On November 20, 2012, a free shuttle designated as H replaced the Rockaway portion of the A service between Far Rockaway–Mott Avenue and Beach 90th Street via the Hammels Wye. On May 30, 2013, full service
2461-555: 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
2568-412: 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
2675-748: 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
2782-462: Is used for testing of equipment. The track to the east of the original tracks, track F6, is used for reversing trains on the Rockaway Park shuttle, and is approximately as long as a standard full length train. This track allows the shuttle to turn around significantly faster than it had been able to do before, when it was forced to relay at Howard Beach–JFK Airport or Euclid Avenue . South of
2889-627: 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
2996-614: The Far Rockaway and Rockaway Beach Branches . Plans for the New York City Subway to take over the Long Island Rail Road (LIRR)'s Rockaway branches were put forth as early as 1932. The Long Island Rail Road's wooden trestle over Jamaica Bay often caught fire. A fire that started at 3:30 on a December night damaged 1,300 feet of the trestle. Service could not be resumed for several days because of
3103-752: 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
3210-474: The IND Fulton Street Line . On June 28, 1956, service on the line began between Euclid Avenue and Rockaway Park at 6:38 PM and between Euclid Avenue and Wavecrest at 6:48 PM. Once the slow order was removed, the travel time from Euclid Avenue to Rockaway Park decreased from 40 to 28 minutes, and the travel time from Euclid Avenue to Wavecrest decreased from 44 to 32 minutes. In September 1956,
3317-429: 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

In 1986, the New York City Transit Authority launched a study to determine whether to close 79 stations on 11 routes, including the segment of the Rockaway Line south of Howard Beach, due to low ridership and high repair costs. Numerous figures, including New York City Council member Carol Greitzer , criticized
3531-740: 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
3638-578: 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
3745-589: 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
3959-450: 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
4066-409: 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
4173-432: 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

Trains operated slowly across Jamaica Bay in order to conserve power. The newer R10s were intended to operate over the line, but because they required more power than the R1–9 fleet , the R1–9 fleet operated on the line instead. The line was incorporated into the Independent Subway System (IND) and connected to

South of the drawbridge is Hammels Wye, a three-legged junction with the respective Rockaway Park and Far Rockaway branches. The tracks from each branch connect to the tracks north of
4815-471: The IND Rockaway Line's connection to the rest of the system, the blue H shuttle provided service from Far Rockaway–Mott Avenue to Beach 90th Street . The Rockaway Shuttle started operating on June 28, 1956. During its early years, it essentially provided non-rush hour and weekend service between Euclid Avenue and either Far Rockaway–Mott Avenue or Rockaway Park–Beach 116th Street . At first,

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
5136-542: The New York City Transit Authority announced that the Rockaway revenues were disappointing, as $ 15,000 was expected to be made every day during the summer, while only $ 7,000 was made. As a result, there was a $ 750,000 deficit. On January 27, 1957, as a result of low ridership, service was reduced from running on eight minute headways to Broad Channel to twelve minute headways. Since service alternated between Rockaway Park and Wavecrest, stations had
5243-533: The North Channel Swing Bridge. The crossing across Jamaica Bay between Howard Beach and Broad Channel is the longest distance between any two adjacent stations in the entire New York City Subway system. In 1997 to 1999, outer tracks were installed to the north of Broad Channel for between $ 5 million and $ 10 million. The track to the west of the original tracks, track F5, extends slightly less than two miles, or 10,300 feet (3,100 m), and
5350-551: The Rockaway Park Shuttle was extended from Broad Channel to Rockaway Boulevard to allow passengers on both Lefferts Boulevard and Far Rockaway-bound A trains to transfer to the shuttle and shuttle passengers to transfer to more frequent Manhattan-bound A service at Rockaway Boulevard. Since then, the seasonal extension has occurred on an annual basis. In 2022, the Metropolitan Transportation Authority (MTA) hired Schiavone to conduct repairs to
5457-493: The Rockaway Park Shuttle, which would run between Broad Channel and Rockaway Park, and C service would be truncated to Euclid Avenue. In April 1992, the MTA Board approved the proposed change to service in the Rockaways, which were expected to encourage ridership growth in the long term, and reduced NYCTA's annual operating budget by $ 20,000. The changes took effect on October 23, 1992. Formerly, some maps and trains had shown

The line then continues as a four track line, and south of Howard Beach , the tracks merge into two tracks. The line then passes over Jamaica Bay just to the east of Cross Bay Boulevard, on its own private right-of-way. Then the line passes over
5671-416: The aftermath of Hurricane Sandy , due to track being washed out between Broad Channel and Howard Beach . On November 20, 2012, a free shuttle designated as H replaced the Rockaway portion of the A service between Far Rockaway–Mott Avenue and Beach 90th Street via the Hammels Wye. Additionally, the remainder of the Rockaway Line from Beach 90th Street to Rockaway Park was damaged and awaited repair. With
5778-478: 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
5885-421: The current S service in blue. Since May 2004, the official system map shows the Rockaway Park Shuttle as carrying a grey bullet. Recent prints, however, depicted the service itself in blue, but has been changed back to grey, as of January 2013. In order to distinguish it from the other shuttles, NYCT Rapid Transit operations still refers to it internally as the H. The Rockaway Park Shuttle was suspended following
5992-455: The designation S is also sometimes used on public documents. Prior to 1993, the Rockaway Park Shuttle used multiple different designations, including the E, CC, and H, which had an emblem colored blue. The H formerly ran north to Euclid Avenue in Brooklyn via the IND Fulton Street Line , as well as to Far Rockaway–Mott Avenue to the east. In 2012–13, after Hurricane Sandy destroyed
6099-414: 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

Like the other two shuttles, 42nd Street in Manhattan and Franklin Avenue in Brooklyn , it is marked with the letter "S" and its route bullet is colored dark gray on route signs, station signs, rolling stock, and the official subway map. The internal designator for this service is H , though the MTA does not show this on any maps, train rollsigns, or schedules;
6313-406: The emergency implementation of this service, the H rollsign designation returned to public usage for the first time since 1993. Despite the service's free status, few riders used the signed H service, partly due to the extremely low ridership at Rockaway stations to begin with; this ridership had been lowered further since Hurricane Sandy. In addition, the service did not run during late nights, and
6420-611: 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

6848-654: The line first saw service by the Long Island Rail Road from its Atlantic Branch . In the late 1890s, the Brooklyn Elevated Railway (later the Brooklyn Rapid Transit Company ) received permission to operate elevated trains from Brooklyn on the line for beach access. The city soon began eyeing the line as popularity soared. Additionally, the Ocean Electric Railway used part of the line as a connection between

Passengers traveling only within the double-fare zone would request a special "refund ticket", entitling them to a refund upon exiting the system, either in cash or a token. The unpopular double fare was abolished on September 1, 1975, though it coincided with a system-wide fare increase, as well as an increase in tolls on
7169-540: The line then became the IND Rockaway Line. The following services use part or all of the IND Rockaway Line: The north end of the Rockaway Line is a junction with the IND Fulton Street Line just east of Rockaway Boulevard . The line starts out as tracks F3 and F4 and descend from an elevated structure to the surface. Then the right-of-way widens to be four tracks wide. Trains in service going south then diverge from F3, and go onto F1. Trains coming from

The first phase would entail repairing the South Channel Bridge and Hammels Wye structure. The project entailed demolishing and completely reconstructing about 1,600 feet (490 m) of viaduct. As a result, service between Howard Beach and the peninsula will be suspended for 17 weeks beginning on January 17, 2025, and

The service pattern devised was designed to improve operations by reducing route length and complexity, making service more attractive, simplifying confusing service patterns, and reducing transfers for passengers traveling during late nights. At
7704-418: 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
7811-402: 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
7918-958: 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
8025-603: 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
8132-587: 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
8239-403: The peninsula, with a terminus at Rockaway Park–Beach 116th Street . The fully above-ground route operates on trackage that was originally part of the Long Island Rail Road 's Rockaway Beach Branch until the mid-1950s. During summer weekends, to eliminate an additional transfer and thus ease beach access, the Rockaway Park Shuttle is typically extended four stations north to Rockaway Boulevard ,
8346-449: The plans. A significant service improvement on the Rockaway Line took effect in 1993, when direct late-night service between Far Rockaway (but not Rockaway Park) and Brooklyn and Manhattan began; previously, only shuttle or Round Robin service was provided during these hours, with a transfer at Euclid Avenue (the Rockaway Park branch remains a shuttle at all times, with a transfer at Broad Channel, although additional direct rush hour service
8453-409: The railroad made it clear that it was not planning to rebuild the line, the city bought the line on June 11, 1952, for $ 8.5 million. The LIRR needed the money for its big safety program, which cost $ 6 million. The New York City Board of Transportation , operators of the subway system, started preparing contracts for the reconstruction of the line right after the sale went through. In total, $ 47.5 million
8560-908: 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
8667-534: The route did not have an official assigned letter code on maps, although sometimes trains displayed either the A or E route on their rollsign boxes. Beginning on February 1, 1962, the Rockaway Shuttle was officially lettered on maps and trains as HH (which had last been used for the Court Street Shuttle , discontinued 16 years earlier) to make it easier to distinguish E trains from shuttle trains. From November 26, 1967, to September 10, 1972, it
8774-542: 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
8881-509: The service plan was amended for late night service to be replaced by C trains instead. This service change would have been implemented in October 1991, pending approval from the MTA board. In 1991, at a series of meetings, the NYCTA presented proposed changes to A, C, and H service that would shorten the length of the C, simplify the service pattern during late nights to most efficiently serve
8988-476: The service was only connected to the rest of the subway via a shuttle bus to Howard Beach. On May 30, 2013, full service to the Rockaways was restored, and the free H service was discontinued. In late May 2016, the MTA announced that the Rockaway Park Shuttle would be extended from Broad Channel to Rockaway Boulevard on weekends from mid-June until Labor Day 2016. This allowed passengers on both Lefferts Boulevard and Far Rockaway-bound trains to transfer to
9095-465: The shuttle will run between Rockaway Park and Far Rockaway. In addition, there will be shuttle bus service between Howard Beach and the Rockaways. During the closure, fares on the Rockaway Park Shuttle are planned to be waived, and all trips from the LIRR's Far Rockaway station to City Terminal Zone stations are planned to be discounted to $ 2.75. In 2024, as part of a program to upgrade the signaling of
9202-399: The shuttle, and for shuttle passengers to transfer to more frequent A train service at Rockaway Boulevard. This summer weekend extension was implemented again starting in 2017 between Memorial and Labor Days. However, the extension for 2018 ended on July 1 and was replaced by rerouted A trains to Rockaway Park due to construction on Hammels Wye. In 2019, the summer extension was reinstated for
9309-663: 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
9416-473: The temporary H service after Hurricane Sandy . The Rockaway Park Branch, tracks F3 and F4, goes west via an elevated structure over the Rockaway Freeway before terminating at Rockaway Park–Beach 116th Street . Directly to the north of the station is a seven-track storage yard named Rockaway Park Yard. This yard stores the trains for the Rockaway Park Shuttle . To the south of the station is
9523-714: 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
9630-530: 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
9737-757: The time, A service ran to Lefferts Boulevard and Far Rockaway during the day while the C ran to Rockaway Park during rush hours. During late nights, A service ran to Lefferts Boulevard, while service to both branches in the Rockaways was provided by the round-robin H shuttle service to Euclid Avenue. As part of the changes proposed, round-robin shuttle service would be discontinued; late-night A service would operate from Manhattan to Far Rockaway; and service to Lefferts Boulevard and Rockaway Park would be provided by separate shuttle services with timed transfers to through A service. Rush hour local C service to Rockaway Park would be replaced by through A express service. In addition, H service to Rockaway Park would be replaced by
9844-511: 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
9951-601: 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
10058-454: The whole season, while in 2020, the summer extension was reinstated in July. Since then, the seasonal extension has occurred on an annual basis. From April 9 to May 18, 2018, and again from July 2 to September 3, 2018, the shuttle ran between Rockaway Park–Beach 116th Street and Far Rockaway–Mott Avenue due to a planned two-phase program of flood mitigation work along the Hammels Wye. To allow
10165-546: The wye with flying junctions. The Rockaway Park Branch turns to the west and the Far Rockaway Branch turns to the east. The third leg of the wye is a single track that connects the two branches together. This single track, track F6, is not currently used in revenue service. However, it was used as part of the Round Robin service that operated mostly during late nights between 1958 and 1988. It was also used for
10272-559: 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
10379-545: Was assigned the color blue, because in Manhattan it used the IND Eighth Avenue Line . On May 6, 1985, the shuttle's identifier was changed to H (still colored blue) instead of reverting to HH, as the New York City Subway system had abolished two-letter designations by then. In January 1991, a reduction of service along the Central Park West corridor to remove excess capacity was proposed. As
10486-438: Was built to better serve the beach resorts in the Rockaways, cutting travel times by 30 minutes over the existing South Side Railroad route. Long Island Rail Road (LIRR) trains began using the branch that year by operating over its Montauk Division. The railroad was sold to the LIRR in 1887, and trains using the branch began serving Far Rockaway via a new connection to the old Far Rockaway Branch. The line south of Woodhaven Junction
10593-437: Was colored red, with daytime non-rush hour and weekend service usually available between Rockaway Park and Euclid Avenue or Broad Channel , plus some weekday mid-afternoon service provided between Far Rockaway and Euclid Avenue. During the late night-early morning hours, service operating to and from Euclid Avenue on the IND Fulton Street Line in Brooklyn was extended between roughly midnight and 6:00 a.m., which were
10700-560: Was delayed the following day. The worst fire, the one that sealed the fate of the line, took place on May 7, 1950. The fire burned all night and destroyed 1,800 feet (550 m) of the trestle between The Raunt and Broad Channel stations, and the estimated cost to repair it was $ 1 million. As a result, the LIRR deemed the line useless, and instead of repairing it, the LIRR decided to abandon the line in favor of their "land route" to Far Rockaway via Valley Stream in Nassau County. When
10807-899: 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
10914-480: Was electrified in 1905. The wooden trestle through Jamaica Bay was subjected to numerous fires, which damaged it. A fire on May 7, 1950, cut service on the middle of the line, but as the LIRR was bankrupt, it did not seek to restore service on the line. Service to Far Rockaway and Rockaway Park ran through Valley Stream, while service on the Rockaway Beach Branch terminated at Hamilton Beach. The line
11021-632: Was extended all the way to Jamaica–179th Street on the IND Queens Boulevard Line in Queens . Afterward, the designation CC (colored green) was used for the shuttle, running to Broad Channel, although during rush hours this train was extended all the way to Bedford Park Boulevard on the IND Concourse Line in the Bronx . In 1979, the MTA released a new coloring scheme for subway routes based on trunk line; CC service
11128-702: 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
11235-470: Was restored. In 2018, a two-phase program of flood mitigation work along the Hammels Wye required further service disruptions. The first phase, from April 9 to May 18, suspended rush-hour A trips to Rockaway Park. The second phase, from July 2 to September 3, diverted all Far Rockaway A trips to Rockaway Park. In both phases, the shuttle ran from Rockaway Park to Far Rockaway. During weekends between Memorial Day and Labor Day in 2016 and 2017, weekend service on
11342-469: Was spent to rebuild the line and to convert it for subway use, something they were planning to do as far back as the late 1920s . As part of the construction to convert the line to subway use, two new steel swing bridges were built to cross the North and South Channels, and two artificial islands were built using sand from Jamaica Bay to provide a roadbed for the subway trestle. Work was completed right before
11449-611: Was then purchased by the New York City Board of Transportation in 1952, and the line south of Ozone Park was taken out of service in June 1955 to allow for the line's conversion to subway service. On June 26, 1956, the line opened for subway service. A connection was built between to the IND Fulton Street Line at Liberty Avenue using the old Fulton Street Elevated line to allow for its use by the subway, and
