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.
96-418: The IRT Pelham Line is a rapid transit line on the New York City Subway , operated as part of the A Division and served by the 6 and <6> trains. It was built as part of the Dual Contracts expansion and opened between 1918 and 1920. It is both elevated and underground with Whitlock Avenue being the southernmost elevated station. It has three tracks from the beginning to just south of
192-425: 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
288-450: 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
384-646: 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
480-521: A complete overhaul as part of the Enhanced Station Initiative . The stations receiving renovations are Third Avenue–138th Street , Brook Avenue , Hunts Point Avenue , and Westchester Square–East Tremont Avenue . Updates would include cellular service, Wi-Fi, USB charging stations, interactive service advisories and maps, improved signage, and improved station lighting. However, in April 2018, it
576-642: A connection with the IRT Pelham Line near Westchester Avenue at the Whitlock Avenue station, and station platforms north to Pelham Bay Park would be narrowed and lengthened to accommodate the longer and wider B Division trains from the Second Avenue Subway. IRT local service on the Pelham Line would terminate at Hunts Point Avenue one stop south. This project would have helped relieve overcrowding on
672-565: 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
768-405: 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
864-418: 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
960-629: 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 ,
1056-452: 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

#17328525226351152-602: 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
1248-407: A planned subway under Gerard Avenue. The three-track line would have then continued east under 138th Street to Southern Boulevard. It would then emerge as an elevated structure and continue via Southern Boulevard and Westchester Avenue to the "former village of Westchester." It was decided to have a portion of the line be constructed on an elevated structure due to the higher cost of building subways in
1344-479: A proposed $ 658 million construction program, the entire Pelham Line would have been connected to the Second Avenue Subway , with service being tripled on the Pelham Line. The IRT Pelham Line would be very easily converted to B Division standards, and connected to the Second Avenue Subway as Route 132–B of the 1968 Program for Action . Second Avenue Subway trains would run east under 138th Street, then along
1440-751: A rapid transit setting. Parkchester station [REDACTED] The Parkchester station (originally Parkchester–177th Street station ) is an express station on the IRT Pelham Line of the New York City Subway . It is located above Hugh J. Grant Circle in the Parkchester neighborhood of the Bronx , where East 177th Street (the Cross Bronx Expressway service road), Metropolitan Avenue, and Westchester Avenue intersect. The station
1536-572: A result, 6 trains run local on the Pelham Line south of Parkchester and short turn there. <6> trains make all stops north of Parkchester, then run express using the center track between that station and Third Avenue–138th Street in the peak direction. At all other times, 6 trains run local on the entire line. Beginning at a junction with the IRT Jerome Avenue Line north of the Lexington Avenue Tunnel at 135th Street,
1632-558: 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
1728-592: 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
1824-770: 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
1920-608: 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
2016-407: Is an express station with three tracks and two island platforms . The 6 stops on the outer local tracks while the <6> stops on the center express track. The 6 train serves the station at all times, and the <6> runs during weekdays in the peak direction. The next stop to the south is Hunts Point Avenue for express trains and St. Lawrence Avenue for local trains, while the next stop to

#17328525226352112-506: 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
2208-416: 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
2304-548: 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
2400-598: Is served by the 6 train at all times and the <6> train during weekdays in the peak direction. By passenger count, Parkchester was the third-busiest station in the Bronx in 2017, behind 161st Street–Yankee Stadium and Third Avenue–149th Street , and the busiest station on the Pelham Line. In 1913, New York City, the Brooklyn Rapid Transit Company , and the Interborough Rapid Transit Company (IRT) reached an agreement, known as
2496-412: 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
2592-733: 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
2688-587: Is transformed into an elevated line over Whitlock Avenue at East 165th Street, but shortly after this encounters the Whitlock Avenue Subway station and curves east over Westchester Avenue which runs over Sheridan Boulevard , the Harlem River and Port Chester Railroad line, and the Bronx River . The line remains over Westchester Avenue throughout the rest of its journey. East of Morrison Avenue station ,
2784-635: The Dual Contracts , to dramatically expand subway service across the City. The portion of the agreement between New York City and the IRT was known as Contract 3. As part of this contract, the IRT agreed to construct a branch of the original subway , which opened in 1904, north along Lexington Avenue with branches along Jerome Avenue and a three-track branch running northeast via 138th Street, Southern Boulevard and Westchester Avenue to Pelham Bay Park. The construction of
2880-605: 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
2976-724: 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

3072-573: The Lexington Avenue Line , in conjunction with the construction of the Broadway–Seventh Avenue Line would change the operations of the IRT system. Instead of having trains go via Broadway, turning onto 42nd Street, before finally turning onto Park Avenue, there would be two trunk lines connected by the 42nd Street Shuttle . The system would be changed from looking like a "Z" system on a map to an "H" system. One trunk would run via
3168-429: 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
3264-722: 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
3360-578: 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
3456-517: The Pelham Bay Park terminal. The Pelham Line also has a connection to Westchester Yard, where 6 trains are stored, just north of Westchester Square–East Tremont Avenue . On March 1, 1905, the Board of Rapid Transit Commissioners laid out its tentative plans for new subway routes to expand the city's first subway , which had opened on October 27, 1904. A preliminary report was released on March 9, and
3552-577: 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
3648-656: 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
3744-610: The accessibility of the New York City Subway system , the MTA announced that it would install elevators at the Parkchester station as part of the MTA's 2020–2024 Capital Program. In December 2022, the MTA announced that it would award a $ 146 million contract for the installation of eight elevators across four stations, including Parkchester. The work would include demolishing an existing escalator to make way for an elevator. Parkchester
3840-450: 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
3936-409: 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

It has a crossunder and windows in a simulated 12-pane pattern similar to those at Whitlock Avenue . The fare control is at street level and the room features a painting entitled Live The Dream . There is an escalator from fare control to
4128-432: 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
4224-463: The 1920s. A report, "Proposed Subway Plan for Subway Relief and Expansion" by Major Philip Mathews, published on December 24, 1926, proposed a connection from the Pelham Line to a newly proposed four-track Third Avenue subway that would run to City Hall and Downtown Brooklyn . When the New York, Westchester and Boston Railway was abandoned in 1937, one proposal for the replacement IRT Dyre Avenue Line
4320-480: 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
4416-536: 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
4512-528: 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
4608-589: The Bronx, whose soil was irregular and rocky. On July 14, 1905, the New York City Board of Estimate adopted resolutions approving the routes planned by the Rapid Transit Board, including for this route. On March 19, 1913, New York City, the Brooklyn Rapid Transit Company , and the Interborough Rapid Transit Company (IRT) reached an agreement, known as the Dual Contracts , to drastically expand subway service across New York City. As part of Contract 3 of
4704-588: The IRT Lexington Avenue Line, which is the busiest line in the country. Under Phase 2 of the Program for Action , the Pelham Line would have been extended to a modern terminal in the Co-op City housing complex. Due to the 1975–1976 fiscal crisis that affected the city, most of the remaining projects did not have funding, so they were declined. Expected to be completed by the mid-1970s and early 1980s, lines for
4800-554: The IRT Pelham Line runs beneath 138th Street for the first three stations in Mott Haven, then curves to the northeast along eastbound Bruckner Boulevard before shortly curving north again along Southern Boulevard . After 145th Street at Samuel Gompers High School , the line curves to the northeast continuing to run under Southern Boulevard. The line returns under eastbound Bruckner Boulevard again, only to leave at Whitlock Avenue and begins to emerge from underground at Aldus Street. The line
4896-479: The IRT Pelham Line was opened to Third Avenue–138th Street . On January 7, 1919, the Pelham Line was extended to Hunts Point Avenue . The extension was originally supposed to be finished by the end of 1918, but due to the difficulty in acquiring materials, the opening was delayed. In January 1919, the Public Service Commission was acquiring property for a subway yard at Pelham Bay Park. On May 30, 1920,

After discharging passengers on the northbound local track, terminating trains use the center track past switches north of the station as a pocket track to relay. All trains continuing on the IRT Pelham Line north of this station make all subsequent stops, these stations are only served by
5088-406: The Pelham Line was extended to East 177th Street . Service between Hunts Point Avenue and East 177th Street was originally served by a shuttle service operating with elevated cars. On October 24, 1920, it was extended to Westchester Square , and on December 20, it was extended to the western edge of Pelham Bay Park . Service to Pelham Bay Park was served by a mix of through and shuttle trains during
5184-536: The Program for Action had to be reduced or canceled altogether due to the 1970s fiscal crisis . The following services use part or all of the IRT Pelham Line: Express service operates between Parkchester and Third Avenue–138th Street during weekdays from approximately 6:30 a.m. to 8:45 p.m. At those times, Pelham Bay Park cannot handle the large number of 6 and <6> trains in service. As
5280-501: The agreement, between New York City and the IRT, the original subway opened by the IRT in 1904 to City Hall , was to be extended north from Grand Central along Lexington Avenue into the Bronx, with a branch running northeast via 138th Street, Southern Boulevard and Westchester Avenue to Pelham Bay Park. In November 1915, the New York Public Service Commission approved plans for the construction of Section 2 of
5376-474: 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
5472-414: 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

All of these projects would allow for quicker main line service and train movements in and out of the yard. The grade separation allowed trains to enter Westchester Yard without crossing the express track or the downtown local track and it allowed for the possibility of the extension of express service to Pelham Bay Park, which would save four more minutes. The increased capacity of

At the time, work on Sections 1 and 1A, between 138th Street and Park Avenue and Southern Boulevard and Whitlock Avenue, was 75 percent complete. The IRT Lexington Avenue Line opened on July 17, 1918, and the first section of the IRT Pelham Line opened to Third Avenue–138th Street on August 1, 1918. On August 1, 1918, a branch of the IRT Lexington Avenue Line ,
5856-421: The final report was completed on March 30, before two further amendments were made on April 13 and May 12, 1905. On June 1, 1905, the Board adopted resolutions laying out multiple routes across the city, including Route 19, a line along Southern Boulevard and Westchester Avenue. The route was planned to begin at 138th Street and Third Avenue, with connections either with new subway lines to Manhattan, or to Route 17,

This would have allowed an extension of express service from Parkchester to Pelham Bay Park. The Westchester Yard was expanded between 1946 and 1949 and the scope of the project included a new signal tower, signal installations, and
6144-447: The increase in ridership from the huge Parkchester housing complex at East 177th Street. This station was rehabilitated in 2010. The northbound platform was partially closed in April 2010 for renovations, followed by the southbound platform that July. The work included new canopies, stairs, lighting, and public intercom systems, as well as refurbished platform floors and structural repairs. In 2019, as part of an initiative to increase

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
6624-545: 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
6720-424: The middle track between East 177th Street and Third Avenue–138th Street. This express service saved eight minutes between Third Avenue and East 177th Street. During this time, 6 trains that ran local in the Bronx when express trains operated began to terminate at East 177 Street to make room for express trains to Pelham Bay Park. Express service did not start until this date because of the increase in ridership from
6816-688: The name "Pelham 123". After the release of the 1974 film adaptation , the New York City Transit Authority banned any schedule of a train leaving this station at 1:23 am or 1:23 pm. Eventually this policy was rescinded, but due to the superstitions involved, dispatchers have continued to avoid scheduling a Manhattan-bound train to leave at 1:23. 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
6912-418: 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

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
7200-479: The north is Castle Hill Avenue . There are 1950s-style mushroom-shaped lights at the end of the platforms and the staircases to the mezzanine are sheltered. Just north of the station is a signal tower which was used until the late 1990s, when a new master tower was created in Westchester Yard. During weekdays, some 6 local trains terminate at Parkchester. All local trains end their runs at Parkchester during
7296-949: 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
7392-588: 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
7488-582: 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
7584-908: 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
7680-548: The right-of-way of Amtrak 's Northeast Corridor from 138th Street to a point near the Bruckner Expressway and Westchester Avenue as an express bypass of the Pelham line, after which the line would split into a Pelham branch and a Dyre Avenue branch. The Brook Avenue station just east of Third Avenue–138th Street on the IRT Pelham Line would be reconstructed to allow a cross-platform interchange . Further north, there would be
7776-583: The road runs over the Bronx River Parkway , and enters Parkchester . The station named after the neighborhood runs over the Hugh J. Grant Circle , which is also over the Cross Bronx Expressway . East of Castle Hill Avenue station , Westchester Avenue branches off to the northeast at Waterbury Avenue (which runs in the same direction prior to that branching), and the line follows. After the Westchester Yard
7872-525: 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
7968-568: The shuttle at Hunts Point Avenue. Express service on the Pelham Line between East 177th Street and Third Avenue–138th Street was inaugurated on October 14, 1946. Express trains ran during weekday rush hours and on Saturday morning in the peak direction. This express service saved eight minutes between Third Avenue and East 177th Street. During this time, 6 trains that ran local in the Bronx when express trains operated terminated at East 177th Street to make room for express trains to Pelham Bay Park. Express service did not start until this date because of
8064-636: 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
8160-706: 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
8256-519: 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
8352-511: 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
8448-591: 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
8544-432: The yard allowed for storage of 358 additional subway cars. With the additional space, it would no longer be required to lay up trains on the middle track of the line between East 177th Street and Pelham Bay Park, and it would allow for full day express service. The construction of substations would improve voltage conditions and allow for longer trains to be operated on the line. The work was projected to cost $ 6,387,000 and it
8640-540: 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
8736-453: Was announced that cost overruns had forced the MTA to reduce the number of subway stations included in the program from 33 stations to 20. The stations to be renovated on the IRT Pelham Line were among the 13 stations without funding, which will be pushed back to the 2020–2024 Capital Program. As part of a 1951 plan by the New York City Board of Transportation, the capacity on the Pelham Line would have been increased. In March 1954, as part of
8832-845: 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) 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
8928-681: 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
9024-546: Was originally supposed to be finished by the end of 1918, but due to the difficulty in acquiring materials, the opening was delayed. In January 1919, the New York State Public Service Commission was looking into acquiring property for a subway yard at Pelham Bay Park. On May 30, 1920, the Pelham Line was extended to Parkchester–East 177th Street, with the extension being served by a shuttle service operating with elevated cars. Passengers transferred to
9120-479: Was projected to be completed in 1950. On August 27, 1953, the New York City Transit Authority approved a plan to lengthen trains along the Pelham Line from seven cars to eight cars during rush hours. The change took place on September 8, 1953. The 2015–2019 Metropolitan Transportation Authority (MTA) Capital Program called for four of the Pelham Line's stations, along with 29 others, to undergo
9216-892: Was to connect the line to the IRT Pelham Line at Whitlock Avenue, rather than its current terminus at East 180th Street on the IRT White Plains Road Line . On June 6, 1946, the New York City Board of Transportation announced that a contract for the installation of signal equipment that would allow express service to run on the Pelham Line was jointly awarded to the Emerson–Garden Electric Company and L. K. Comstock & Company Incorporated for $ 129,516. The signals were to be installed between Third Avenue–138th Street and Parkchester. Beginning October 14, 1946, weekday rush and Saturday morning rush peak direction express service started, with Pelham Bay trains using
