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.
121-607: Bay Area Rapid Transit ( BART ) is a rapid transit system serving the San Francisco Bay Area in California . BART serves 50 stations along six routes and 131 miles (211 kilometers) of track, including eBART , a 9-mile (14 km) spur line running to Antioch , and Oakland Airport Connector , a 3-mile (4.8 km) automated guideway transit line serving San Francisco Bay Oakland International Airport . With an average of 169,800 weekday passenger trips as of
242-686: A Golden State Warriors game. That easily surpassed the previous Saturday record of 319,484 riders, which occurred in October 2012, coinciding with several sporting events and Fleet Week . BART set a Sunday ridership record of 292,957 riders in June 2013, in connection with the San Francisco Gay Pride Parade , surpassing Sunday records set the previous two years when the Pride Parade was held. Ridership dropped sharply during
363-924: A $ 7 million contract (equivalent to $ 39 million in 2023). It was the third system in the US to use encoded-value magnetic stripe tickets, following the Illinois Central Gulf commuter line in 1964 and the PATCO Speedline in 1968. Although tickets could be refilled at fare machines, riders often discarded tickets with small values remaining. BART formerly relied on unused ticket values on such discarded cards for additional revenue – as much as $ 9.9 million annually in 1999 (equivalent to $ 17 million in 2023). Tickets stopped being sold in December 2020 in favor of Clipper cards, and can no longer be used. A 50-cent surcharge per trip (25 cents for discounted fares)
484-475: A 62.5% discount is provided to seniors and the disabled. The Clipper START program for low-income adults provides a 50% discount. The San Francisco Muni and BART offer a combined monthly "A" Fast Pass, which allows unlimited rides on Muni services plus BART service within San Francisco. In August 2022, BART launched Clipper BayPass, a two-year pilot program to examine the viability of a transit pass that

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
726-454: 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
847-651: 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
968-583: 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
1089-405: 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
1210-566: A feasibility study for installing a second transbay crossing would commence the following year. By 2019, the Capitol Corridor Joint Powers Authority (CCJPA) had joined with BART to study a multi-modal crossing, which could also allow Capitol Corridor and San Joaquins routes to serve San Francisco directly. In 2007, BART stated its intention to improve non-peak (night and weekend) headways for each line to 15 minutes. The 20-minute headways at these times
1331-476: A fifth line to the system for the first time in BART's history. The system was expanded to San Francisco International Airport in 2003 and to Oakland International Airport (now San Francisco Bay Oakland International Airport) via an automated guideway transit spur line in 2014. eBART , an extension using diesel multiple units along conventional railroad infrastructure between Pittsburg/Bay Point and Antioch on

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
1573-652: 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 ,
1694-452: 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
1815-615: 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

Despite the fact that Marin had originally voted in favor of BART participation at the 88% level, its marginal tax base could not adequately absorb its share of BART's projected cost. Another important factor in Marin's withdrawal was an engineering controversy over the feasibility of running trains on the lower deck of the Golden Gate Bridge , an extension forecast as late as three decades after
2057-403: A nationwide decline in mass transit ridership in the second half of the decade. The Washington Post and LA Streetsblog attributed the national decline in ridership to changes in commute patterns, the fall in gasoline prices since 2014, and competition from the private sector in the form of ride-hailing services such as Uber and Lyft. Ride-hailing has especially affected ridership on the lines to
2178-701: A number of major engineering challenges, including excavating subway tunnels in San Francisco, Oakland, and Berkeley; constructing aerial structures throughout the Bay Area, particularly in Alameda and Contra Costa counties; tunneling through the Berkeley Hills on the Concord line; and lowering the system's centerpiece, the Transbay Tube connecting Oakland and San Francisco, into a trench dredged onto
2299-409: A paper-plastic composite with a magnetic stripe . The tickets were sold by fare vending machines. When exiting, fare gates read the magnetically stored value on the card, encoded the new value with the fare subtracted, and printed the new value on the card. Tickets with no remaining value were retained by the machine rather than being returned. The entire fare system was designed and built by IBM under
2420-583: A rapid transit setting. Antioch station (BART) Antioch station is a Bay Area Rapid Transit (BART) station on the Yellow Line . It is located in the median of Highway 4 at Hillcrest Avenue in Antioch, California . Antioch station is the eastern terminus of the BART to Antioch ( eBART ) section of the line. The station is expected to attract passengers from Oakley , Brentwood , and Discovery Bay , communities that were envisioned as part of
2541-565: 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

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
2783-613: Is a barrier to ridership. In mid-2007, BART temporarily reversed its position, stating that the shortened wait times would likely not happen due to a $ 900,000 state revenue budget shortfall. Nevertheless, BART eventually confirmed the implementation of the plan by January 2008. Continued budgetary problems halted the expanded non-peak service and returned off-peak headways to 20 minutes in 2009. In 2008, BART announced that it would install solar panels at two yards, maintenance facilities, and Orinda station (the only station that receives sufficient sunlight to justify installation cost). In 2012,
2904-801: 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
3025-608: 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
3146-453: Is applied to all journeys made on paper tickets. However, due to supply chain shortages resulting in a lack of plastic Clipper cards, BART started issuing tickets again at the SFO station in October 2022. Sales of paper tickets again ended on September 30, 2023, and they were no longer usable after November 30. BART first piloted a smart card for fare payment called EZ Rider in 2006; this program
3267-529: Is at 41% of pre-pandemic levels, Saturday ridership is at 63%, and Sunday ridership is at 75%. In a 2022 survey, 31% of riders report household income below $ 50,000 (up from 26% in 2018), and 44% did not own a vehicle (up from 31% in 2018). Compared to the region, BART riders are more likely to be Black or Latino, and less likely to be White or Asian. The entirety of the system runs in exclusive, grade-separated right-of-way. BART's rapid transit revenue routes cover about 131 miles (211 km) with 50 stations. On
3388-506: 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
3509-629: Is compatible with all the public transit agencies in the Bay Area. The program was initially made available to around 50,000 college students and affordable housing residents. The primary fare media for BART is the Clipper card , which is used by most Bay Area transit agencies. Clipper is a contactless smart card ; passengers tap in and out at card readers on fare gates. Clipper cards in Apple Pay and Google Wallet electronic wallets can also be used. BART's original fare system used tickets made of
3630-617: Is located one block from Embarcadero and Montgomery stations. Several transit agencies offer limited commuter-oriented bus service from more distant cities to outlying BART stations; these include VINE from Napa County, Solano Express from Solano County, Rio Vista Delta Breeze , Stanislaus Regional Transit Authority from Stanislaus County, and San Joaquin RTD from Stockton. Many BART stations are also served by privately run employer and hospital shuttles, and privately run intercity buses stop at several stations. BART also runs directly to two of
3751-416: 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

3872-502: Is planned to be completed by 2036. Plans had long been floated for an extension from Dublin to Livermore, but the most recent proposal was rejected by the BART board in 2018. Other plans have included an extension to Hercules, a line along the Interstate Highway 680 corridor, and a fourth set of rail tracks through Oakland. At least four infill stations such as Irvington and Calaveras on existing lines have been proposed. With
3993-555: 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
4114-438: Is separated from the rest of the line. BART has elements of both traditional rapid transit (high-frequency urban service with close station spacing) and commuter rail / regional rail (lower-frequency suburban service with wider station spacing). Trains on each primary service run every 20 minutes, except the busy Yellow Line, which operates every 10 minutes on weekdays. Segments served by multiple lines have higher frequencies,
4235-412: 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
4356-748: 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
4477-465: Is working to implement a 30-minute "grace period" before the fare is charged. Unlike many other rapid transit systems, BART does not have weekly or monthly passes with unlimited rides. The only discount provided to the general public is a 6.25% reduction when "high value tickets" (only available on Clipper cards with autoload) are purchased with fare values of $ 48 and $ 64. 50% discount is available to youth aged 5–18 (children age 4 and under ride free), and

A 2010 study concluded that along with some Bay Area freeways, some of BART's overhead structures could collapse in a major earthquake, which has a significant probability of occurring within three decades. Seismic retrofitting has been carried out since 2004 upon voter approval to address these deficiencies, especially in
4840-654: The COVID-19 pandemic and associated lockdowns beginning in March 2020, during which BART was forced to drastically cut service. Ridership in the weeks immediately following the start of the Bay Area's lockdown (on March 17, 2020) fell by as much as 93%. If ridership does not recover and additional revenue is not obtained, in the worst case the agency projected it would only be able to sustain trains on three lines running once an hour from 5am to 9pm weekdays, and would have to close nine stations. As of May 2024, weekday ridership

A tunnel at the Powell Street station connects to the Union Square/Market Street station on the Muni Metro T Third Street line. In the South Bay, Milpitas station provides a connection to the Orange Line of VTA light rail . BART is served by bus connections from regional and local transit agencies at all stations, most of which have dedicated off-street bus transfer areas. Many connecting routes (particularly in suburban areas) serve primarily as feeder routes to BART. Larger bus systems connecting to BART include Muni in San Francisco, AC Transit in

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
5808-578: 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

#17328024766576292-450: 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

Some of the early safety concerns appeared to be well founded when the system experienced a number of train-control failures in its first few years of operation. As early as 1969, before revenue service began, several BART engineers identified safety problems with the Automatic Train Control (ATC) system. The BART Board of Directors

Between 2010 and 2015, BART ridership grew rapidly, mirroring strong economic growth in the Bay Area. In 2015, the system was carrying approximately 100,000 more passengers each day than it had five years earlier. High gasoline prices also contributed to growth, pushing ridership to record levels during 2012, with

The first cars were expected to be in service in December 2016, however, glitches and a failed CPUC inspection delayed introduction to January 19, 2018. A total of 775 cars were ordered from Bombardier (which merged with Alstom during production): 310 cab cars (D-cars) and 465 non-cab cars (E-cars). As of July 23, 2024, BART has received all 775 D and E cars, of which 769 have been certified for service. To run its peak service, BART requires 400 cars. Of those, 384 are scheduled to be in active service;

The four-bore tunnel would provide two tunnels for BART and two tunnels for conventional/high-speed rail. The BART system and conventional U.S. rail use different and incompatible rail gauges and different loading gauges . In 2018, BART announced that
8470-473: The Transbay Tube to the San Francisco Peninsula. This service complements the Red Line during daytime hours and replaces that line when it stops operating after 9pm. The first inbound trains leave outer terminals around 5:00 am on weekdays, 6:00 am on Saturdays, and 8:00 am on Sundays and most holidays. The last trains of the service day leave their terminals around midnight; the final Yellow and Orange Line trains in both directions meet at MacArthur station , and
8591-425: The Transbay surcharge, is $ 17.60; the maximum without surcharges ( Antioch – Berryessa/North San José ) is $ 10.30. As of June 2022, the average fare paid is $ 3.93. Because of the varied fares, it is possible to enter the system with enough stored value for a shorter trip, but not a longer trip. Passengers without sufficient fare to complete their journey must use an add-fare machine to add value in order to exit
8712-601: The U.S. economy, growing modestly during periods of economic expansion and dropping slightly during recessions. A major exception occurred in 1989 in the aftermath of the Loma Prieta earthquake , which severely damaged the San Francisco–Oakland Bay Bridge , causing its closure for a month. BART became the only direct route between the East Bay and San Francisco, resulting in a nearly 17% ridership jump for
8833-661: The Yellow Line, opened on May 26, 2018. BART's most significant current extension project is the Silicon Valley BART extension on the Green and Orange Lines. The first phase extended the Fremont line to Warm Springs/South Fremont in early 2017, and the second phase to Berryessa/North San José began service on June 13, 2020. The third phase to Santa Clara is contingent upon the allocation of funding as of May 2020, but
8954-478: 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
9075-484: The busiest of which is the section between Daly City and West Oakland, which has around 15 trains per hour (one train about every four minutes), per direction at peak hours. The Oakland Airport Connector runs "on demand", typically on headways of 10 minutes or less. Timed cross-platform transfers are available between the Orange Line, which operates only in the East Bay, and the Yellow Line, which operates through
9196-532: The cities and suburbs. Marvin E. Lewis, a San Francisco trial attorney and member of the city's board of supervisors spearheaded a grassroots movement to advance the idea of an alternative bay crossing and the possibility of regional transit network. Formal planning for BART began with the setting up in 1957 of the San Francisco Bay Area Rapid Transit District , a county-based special-purpose district body that governs
9317-539: The community and the plans were redesigned to add these features, however the station will only have one employee present at any given time, one agent or one maintenance worker at a time. An extra police beat will be added. This caused concern among Antioch residents and the Antioch Police Department may have to cooperatively police the station. The lack of a full-time station agent has resulted in security issues after opening. A station agent booth
9438-414: 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
9559-537: 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
9680-400: The final Orange and Blue Line trains in the southbound direction meet at Bay Fair station , for guaranteed transfers. Two different bus networks operated by regional transit agencies run during the overnight hours when BART is not operating. The All Nighter network provides basic overnight service to much of the Bay Area. Most BART stations are served (directly or within several blocks) by
9801-653: The floor of San Francisco Bay. Like other transit systems of the same era, BART endeavored to connect outlying suburbs with job centers in Oakland and San Francisco by building lines that paralleled established commuting routes of the region's freeway system. BART envisioned frequent local service, with headways as short as two minutes between trains through the Transbay Tube and six minutes on each individual line. Passenger service began on September 11, 1972, initially just between MacArthur and Fremont . The rest of
9922-516: 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
10043-425: The heavy rail services run through Oakland , and all but the Orange Line cross the bay through the Transbay Tube to San Francisco. All five services run every day until 9 pm; only three services operate evenings after 9 pm. All stations are served during all service hours. The eastern segment of the Yellow Line (between Antioch and the transfer platform east of Pittsburg/Bay Point) uses different rolling stock and
10164-451: The highest ridership, while suburban stations record lower rider numbers. During fiscal year 2017, the busiest station was Embarcadero with 48,526 average weekday exits, followed by Montgomery Street with 45,386. The busiest station outside of San Francisco was 12th Street Oakland City Center with 13,965 riders, followed by 19th Street Oakland with 13,456. The least busy station was Oakland International Airport with 1,517 riders, while
10285-439: 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
10406-534: The least busy standard BART station was North Concord / Martinez with 2,702 weekday exits. BART's one-day ridership record was set on Halloween of 2012 with 568,061 passengers attending the San Francisco Giants' victory parade for their World Series championship . This surpassed the record set two years earlier of 522,198 riders in 2010 for the Giants' 2010 World Series victory parade. Before that,
10527-602: The lines of the Lyon Metro includes a section of rack (cog) railway , while the Carmelit , in Haifa, is an underground funicular . For elevated lines, another alternative is the monorail , which can be built either as straddle-beam monorails or as a suspended monorail . While monorails have never gained wide acceptance outside Japan, there are some such as Chongqing Rail Transit 's monorail lines which are widely used in
10648-473: The lower deck of the Bay Bridge , but the system was dismantled in the 1950s, with its last transbay crossing in 1958, and was superseded by highway travel. A 1950s study of traffic problems in the Bay Area concluded the most cost-effective solution for the Bay Area's traffic woes would be to form a transit district charged with the construction and operation of a new, high-speed rapid transit system linking
10769-476: The main lines, approximately 28 miles (45 km) of lines run through underground sections with 32 miles (51 km) on elevated tracks. 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
10890-557: 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
11011-418: 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
11132-402: 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
11253-958: 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
11374-603: 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
11495-484: The original eBART extension but could not be included due to cost. BART planned to extend service southeast to Brentwood and upgrade the extension to full BART service while pushing the DMU portion further out. Initially planned to open in 2016, the station's service date was delayed until May 26, 2018. Preliminary designs called for a station without an agent present, nor restrooms or escalators. This prompted concern from
11616-535: The others are used to build up spare trains (used to maintain on-time service). The previous BART fleet, consisting of A, B, and C cars, was built between 1968 and 1996. It was retired from regular service on September 11, 2023, with the final revenue runs on April 20, 2024. The Oakland Airport Connector uses a completely separate and independently operated fleet of cable car-based automated guideway transit vehicles. It uses four Cable Liner trains built by DCC Doppelmayr Cable Car , arranged as three-car sets, but
11737-587: 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
11858-908: 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
11979-625: The record was 442,100 riders in October 2009, following an emergency closure of the Bay Bridge . During a planned closure of the Bay Bridge, there were 475,015 daily riders on August 30, 2013, making that the third highest ridership. On June 19, 2015, BART recorded 548,078 riders for the Golden State Warriors championship parade, placing second on the all-time ridership list. BART set a Saturday record of 419,162 riders on February 6, 2016, coinciding with Super Bowl 50 events and
12100-473: The rest of the BART system. The withdrawals of Marin and San Mateo resulted in a downsizing of the original system plans, which would have had lines as far south as Palo Alto and northward past San Rafael . Voters in the three remaining participating counties approved the truncated system, with termini in Fremont , Richmond, Concord, and Daly City, in 1962. Construction of the system began in 1964, and included
12221-542: 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
12342-567: The station . As of June 2022, entering and exiting at the same station incurs an "excursion fare" of $ 6.40 – significantly higher than many station-to-station fares. This was originally introduced to allow people to tour the then-futuristic system; it was kept to discourage undesired behaviors such as tech bus riders using BART parking lots. The excursion fare has been criticized for negatively impacting riders who leave stations during service disruptions (although station agents can allow riders to exit without fare payment). As of December 2022, BART
12463-513: The station's parking facilities and causing riders to illegally park nearby. The station has 1,012 parking spaces. Soon after opening, the agency began planning an additional 1,600 parking space facility north of the station site. In October 2018, BART announced plans for a $ 16.4 million, 800-space lot east of the station, which would open in 2020. In November 2019, the BART board approved a $ 9.9 million contract for an 850-space lot. The new lot opened on November 30, 2021. A 2018 study recommended
12584-663: 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
12705-537: The system can accommodate four-car trains in the future. The eBART extension uses eight Stadler GTW diesel railcars . The Stadler GTW vehicles are diesel multiple units , which operate over standard gauge tracks (as opposed to BART's broad gauge). The initial BART system included car storage and maintenance yards in Concord, Hayward, and Richmond, with an additional maintenance only (no car storage) yard in Oakland. The Daly City car storage and maintenance yard opened in December 1988. The Oakland Airport Connector uses
12826-400: The system expanded into Santa Clara County in 2020, as of June 2024 it is still not a district member. In 1962, San Mateo County supervisors voted to leave BART, saying their voters would be paying taxes to carry mainly Santa Clara County residents (presumably along I-280 , SR 92 , and SR 85 ). The district-wide tax base was weakened by San Mateo's departure, forcing Marin County to withdraw
12947-400: The system opened in stages, with the entire system opening in 1974 when the transbay service through the Transbay Tube began. The new BART system was hailed as a major step forward in subway technology, although questions were asked concerning the safety of the system and the huge expenditures necessary for the construction of the network. Ridership remained well below projected levels throughout
13068-536: The system recording five record ridership days in September and October 2012. After six straight years of expansion, ridership growth began to slow in late 2016, dropping by 1.7% in October 2016 from the prior year. Although the fiscal year ending June 30, 2017, showed an average weekday ridership of 423,395, the second-highest in BART's history, this was a 2.3% drop from FY 2016. Ridership continued to decline by approximately 3% per year between 2016 and 2019, mirroring
13189-714: 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
13310-530: 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
13431-435: The third quarter of 2024 and 48,119,400 annual passenger trips in 2023, BART is the sixth-busiest rapid transit system in the United States . BART is operated by the San Francisco Bay Area Rapid Transit District which formed in 1957. The initial system opened in stages from 1972 to 1974. The system has been extended several times, most recently in 2020, when Milpitas and Berryessa/North San José stations opened as part of
13552-609: The three major Bay Area airports ( San Francisco International Airport and San Francisco Bay Oakland International Airport ) with service to San Jose International Airport provided by a VTA bus route available at Milpitas station . Some of the Bay Area Rapid Transit system's current coverage area was once served by an electrified streetcar and suburban train system called the Key System . This early 20th-century system once had regular transbay traffic across
13673-511: 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
13794-835: The under construction Silicon Valley BART extension in partnership with the Santa Clara Valley Transportation Authority (VTA). BART serves large portions of its three member counties – San Francisco , Alameda , and Contra Costa – as well as smaller portions of San Mateo County and Santa Clara counties. The system has 50 stations : 22 in Alameda County, 12 in Contra Costa County, 8 in San Francisco, 6 in San Mateo County, and 2 in Santa Clara County. BART operates five named heavy rail services plus one separate automated guideway line. All of
13915-601: 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
14036-559: 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
14157-460: Was abandoned in 2010 in favor of a regional farecard. In 2009, BART became one of the first five transit agencies to accept TransLink (later renamed Clipper) cards for fare payment and began phasing out tickets. By December 2020, all BART ticket machines, except for add-fare machines inside of paid areas, were converted to Clipper use only. Tickets were no longer accepted starting in December 2023. For most of its history, BART's ridership has reflected
14278-899: 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
14399-414: Was dismissive of their concerns and retaliated by firing them. Less than a month after the system's opening, on October 2, 1972, an ATC failure caused a train to run off the end of the elevated track at the terminal Fremont station and crash to the ground, injuring four people. The "Fremont Flyer" led to a comprehensive redesign of the train controls and also resulted in multiple investigations being opened by
14520-455: Was later added; the station began to be staffed on March 22, 2021. Installation of second-generation faregates at the station began in September 2024. BART anticipated the station would serve 1,575 round trips per day based upon a supposed opening in 2015. Before the proper opening, BART forecasted 2,270 trips per day. Two weeks following the beginning of service in 2018, ridership was observed to be about 3,000 round trips per day, overloading
14641-702: 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
