List of metro systems

From Wikipedia the free encyclopedia

From top to bottom: The Beijing Subway is the longest metro network. Shanghai Metro is the metro system with the highest annual ridership. The New York City Subway has the most stations in the world. The London Underground is the oldest metro system.

This list of metro systems includes electrified rapid transit train systems worldwide. In some parts of the world, metro systems are referred to as subways, undergrounds, tubes or U-Bahn. As of 6 March 2024, 201 cities in 62 countries have a metro system.

The London Underground first opened as an underground railway in 1863 and its first electrified underground line opened in 1890,[1] making it the world's oldest metro system.[2] The Beijing Subway is the world's longest metro network at 815.2 kilometres (507 mi) and the Shanghai Metro has the highest annual ridership at 2.83 billion trips.[3] The New York City Subway has the greatest number of stations with 472.[4][5] As of 2023, the country with the most metro systems is China, with 46 in operation.

Considerations[edit]

The International Association of Public Transport (L'Union Internationale des Transports Publics, or UITP) defines metro systems as urban passenger transport systems, "operated on their own right of way and segregated from general road and pedestrian traffic".[6][7] The terms heavy rail (mainly in North America) and heavy urban rail are essentially synonymous with the term "metro".[8][9][10] Heavy rail systems are also specifically defined as an "electric railway".[8][9]

The dividing line between the metro and other modes of public transport, such as light rail[8][9] and commuter rail,[8][9] is not always clear. The UITP only makes distinctions between "metros" and "light rail",[6] the American Public Transportation Association (APTA) and Federal Transit Administration (FTA) distinguish all three modes.[8][9] A common way to distinguish metro from light rail is by their separation from other traffic. While light rail systems may share roads or have level crossings, a metro system runs, almost always, on a grade-separated exclusive right-of-way, with no access for pedestrians and other traffic.

In contrast to commuter rail or light rail, metro systems are primarily used for transport within a city, and have higher service frequencies and substantially higher passenger volume capacities. Most metro systems do not share tracks with freight trains or inter-city rail services. It is not relevant whether the system runs on steel wheels or rubber tyres, or if the power supply is from a third rail or overhead line.

The name of the system is not a criterion for inclusion or exclusion. Some cities use "metro" as a brand name for a transit line with no component of rapid transit whatsoever. Similarly, there are systems branded "light rail" that meet every criterion for being a rapid transit system. Some systems also incorporate light metro or light rail lines as part of the larger system under a common name. These are listed, but the light rail lines are not counted in the provided network data.

Certain transit networks may match the service standards of metro systems, but reach far out of the city and are sometimes known as S-Bahn, suburban, regional or commuter rail. These are not included in this list. Neither are funicular systems, or people movers, such as amusement park, ski resort and airport transport systems.

This list counts metros separately when multiple metros in one city or metropolitan area have separate owners or operating companies. This list expressly does not aim at representing the size and scope of the total rapid transit network of a certain city or metropolitan area. The data in this list should not be used to infer the size of a city's, region's, or country's urban rail transit systems, or to establish a ranking.

Legend[edit]

Countries shown in green have at least one operational metro system. Countries shown in yellow have at least one metro system under construction.
City
Primary city served by the metro system.
Country
Sovereign state in which the metro system is located.
Name
The most common English name of the metro system (including a link to the article for that system).
Year opened
Map of all the world's metro systems
The year the metro system was opened for commercial service at metro standards. In other words, parts of the system may be older, but as parts of a former light rail or commuter rail network, so the year that the system obtained metro standards (most notably electrification) is the one listed.
Year of last expansion
The last time the system length or number of stations in the metro system was expanded.
Stations
The number of stations in the metro network, with stations connected by transfer counted as one.
System length
The system length of a metro network is the sum of the lengths of all routes in the rail network in kilometers or miles. Each route is counted only once, regardless of how many lines pass over it, and regardless of whether it is single-track or multi-track, single carriageway or dual carriageway.
Ridership
The number of unique journeys on the metro system every year. There is a major discrepancy between the ridership figures: some metro systems count transferring between lines as multiple journeys, but others do not. Numbers may also be counted via different methods – faregates/turnstiles or light barriers at entrances or vehicle doors being the most common but far from the only ones.

Notes[edit]

System notes[edit]

  1. ^ Line A opened in stages between 1913 and 1914 by the Anglo-Argentine Tramways Company. Line A services continued as above-ground tram services through an access ramp at Primera Junta Station. Subway-surface services into Line A ceased in 1926, with the line and its rolling stock transitioned into pure rapid transit operation by 1927.[14][15]
  2. ^ The number is 78 if interchange stations (i.e. different sets of platforms) are counted as one station, or 90 if all stations on all lines are counted multiple times for each line.
  3. ^ Vienna's Metropolitan Railway (Wiener Stadtbahn) first opened for service in 1898, operating steam locomotive trains on mostly elevated or underground ROWs. From 1976 onwards, part of it was integrated into the newly established Vienna U-Bahn system (lines U4 and U6), operating as a modern metro.
  4. ^ Line 2's loop was completed in 2009.
  5. ^ Not including stations of premetro Lines T3, T4, and T7.
  6. ^ Includes Line 1,2,5 and 6, Line 3,4 and 7 are premetro lines.
  7. ^ Includes Metrofor's rapid transit line only: Linha Sul (South Line).
  8. ^ Includes Metrorec's rapid transit lines only: Linha Centro (Center Line) and Linha Sul (South Line).
  9. ^ Does not include São Paulo Metropolitan Trains system.
  10. ^ The Beijing Subway's first line began trial operations on 1 October 1969. It opened to revenue service under trial operations on 15 January 1971. Initially, only members of the public with credential letters from their work units could purchase tickets, but this restriction was removed on 27 December 1972. The subway line passed its final inspections and ended trial operations on 15 September 1981. During the trial operations period, annual ridership rose from 8.28 million in 1971 to 55.2 million in 1980. See the history section of the Beijing Subway for details and references.
  11. ^ The number of stations is 381 if the 80 (71 2-line, 9 3-line) interchange stations (i.e. different sets of platforms) are counted as one station, or 470 if all stations on all lines are counted multiple times for each line. Both counts exclude the 20 stations of the Xijiao and Line T1 tram lines.[70]
  12. ^ Length excludes the Xijiao and Line T1 tram lines, which combined are 20.7 km long.
  13. ^ Ridership data includes that of Xijiao and Line T1 tram lines.
  14. ^ Opening of metro Line 1 and not light rail Line 3, which opened in 2002.
  15. ^ There are 109 stations if the station on 3 light rail line are counted
  16. ^ There are 140.8 km (87.5 mi) of rail length if 3 light rail line are counted
  17. ^ There are 291 stations if the 51 (46 2-line, 5 3-line) interchange stations (i.e. different sets of platforms) are counted as one station. There are 347 stations if all stations on all lines are counted multiple times for each line. Excludes light rail line T2.
  18. ^ There are 256 stations if the 42 (36 2-line, 6 3-line) interchange stations (i.e. different sets of platforms) are counted as one station. There are 304 stations if all stations on all lines are counted multiple times for each line.
  19. ^ First line of Foshan Metro serves two cities – Foshan and Guangzhou
  20. ^ The 9 station, 4.0-km long APM line is not included here, because it is a people mover.
  21. ^ There are 265 stations if the 43 (40 2-line, 3 3-line) interchange stations (i.e. different sets of platforms) are counted as one station. There are 311 stations if all stations on all lines are counted multiple times for each line.
  22. ^ There are 254 stations if the 44 (40 2-line, 4 3-line) interchange stations (i.e. different sets of platforms) are counted as one station. There are 302 stations if all stations on all lines are counted multiple times for each line.
  23. ^ The first MTR route to offer metro service was the Modified Initial System in 1979, which consists of portions of the later Tsuen Wan Line and Kwun Tong Line. Though the eventual East Rail Line opened as a conventional railway in 1910, it did not offer metro service until at least in 1982 when it was electrified.
  24. ^ As of December 2021, the number of stations is 500 if the 82 interchange stations (i.e. different sets of platforms) (69 2-line, 11 3-line, and 2 4-line) are counted multiple times, once for each line, while there are 403 stations if they are combined; shared tracks/platforms on Lines 3 and 4 are anyway counted as a single stations (nine in all between Hongqiao Road and Baoshan Road).[120]
  25. ^ This figure excludes Pujiang line, Maglev line and Jinshan Railway, all of which often included in Shanghai Metro maps but not considered part of the system.
  26. ^ Ridership excludes Pujiang line, Maglev line and Jinshan Railway.
  27. ^ As of 28 December 2022, there are 373 stations if the 56 interchange stations (48 2-line, 6 3-line, 2 4-line) (i.e. different sets of platforms) are counted multiple times, while there are 307 stations if they are counted as one station.
  28. ^ There are 262 stations if the 35 (32 2-line, 3 3-line) interchange stations (i.e. different sets of platforms) are counted as one station. There are 300 stations if all stations on all lines are counted multiple times for each line.

  33. ^ Opening of Toulouse Metro Line B.
  34. ^ Opening of State University Station on Saburtalo Line.
  35. ^ The U3 extension from Olympia-Einkaufszentrum (OEZ) to Moosach.
  36. ^ The Blue Line (Line 3) also has a 20.7 km (12.9 mi) section (with 4 stations) to the airport that is owned by the Hellenic Railways Organisation and is mainly used by the suburban railway system.[184][185]
  37. ^ The Green Line (Line 1), operated until 2011 by Athens–Piraeus Electric Railways, was opened in 1869 as a steam train railway line. It was electrified in 1904, extended with underground sections through the city in 1948, and extended to its full length to Kifissia in 1957 using the right-of-way of a former metre gauge suburban line. Full metro operation since 1904 between Piraeus and Athens and 1957 to Kifissia. In 2011, it was integrated with Athens Metro under the company STASY S.A.[184]
  38. ^ The network consists of 256 stations if transfer stations are counted more than once. If transfer stations are counted only once, the result will be 231 stations. Ashok Park Main station, where the two diverging branches of Green Line share tracks/platforms, is anyway counted as a single station. Stations of Noida Metro and Gurgaon Metro are not counted. If they were counted, then there would be 288 total stations.[206][207]
  39. ^ The lengths of the Noida Metro and Gurgaon Metro are not counted with the Delhi Metro. If they were counted, the total length of the three systems would be 392.448 km (243.856 mi).
  40. ^ Adelabad station opened
  41. ^ Opening of metro-standards Line 2.
  42. ^ Opening of RajaeeiShahr station.
  43. ^ a b The 43 km (27 mi) Line 1 of Karaj Metro (part of line 5 of Tehran metro) is a commuter rail line, and so is not included in the statistics here. If Line 1 is included, there would be 10 stations.
  44. ^ Opening of metro-standards Line 2.
  45. ^ a b There are 131 stations if interchange stations are counted once, and 146 stations if they are counted multiple times. The 67.5 km (41.9 mi) Line 5 of the Tehran Metro is a commuter rail line, and so is not included in the statistics here – only metro Lines 1–4 and 6–7 are. If Line 5 is included, the total length of the system would be 292.1 km (181.5 mi), and there would be 142 unique stations, and 159 total stations.
  46. ^ Opening of Cibali station in July
  47. ^ As of July 2023, the number is 121 if the 8 interchange stations (i.e. different sets of platforms) are counted multiple times, once for each line, while it is 113 if they are combined.[254][255]
  48. ^ Lines 1, 6, and Naples-Aversa railway only, not line 2, which is commuter rail.
  49. ^ Opening of Duomo station in August
  50. ^ a b c d e f g h i j k In general, the majority of urban rail service in Japanese metropolitan areas is provided by systems not included in this list. For a complete list of urban rail systems in Japan, see List of urban rail systems in Japan.
  51. ^ As of October 2018, the number is 106 if the 7 interchange stations (i.e. different sets of platforms) are counted multiple times, once for each line, while it is 99 if they are combined; Higashi-nihombashi station and Bakuro-yokoyama station, where an out-of-system transfer between Asakusa Line and Shinjuku Line is possible, are anyway counted as two stations.[276][277][278]
  52. ^ Yŏnggwang and Puhŭng opened in 1987.
  53. ^ Line 1
  54. ^ a b c Includes Busan-Gimhae Light Rail Transit
  55. ^ Daegu Metro Line 3 opened in 2015.
  56. ^ Second phase of line 1
  57. ^ Line 1 fully opened
  58. ^ The Seoul Subway Lines 1-9 and Seoul Light Rapid Transit is actually operated by several different operators – Seoul Metro and Seoul Metro Line 9 Corporation (SLM9), plus through-operation services from Korail – but because all of these lines are owned by the City Government of Seoul, here in the table they are counted together as one system.
  59. ^ a b c Seoul's Metropolitan Subway system can also be viewed as a comprehensive metro network made up of multiple owned/operated metro systems. If viewed as such, the combined route length of Seoul's comprehensive metro-standards network would be 564.2 km (350.6 mi).
  60. ^ Statistics presented include rapid transit lines only: Ampang Line, Sri Petaling Line, Kelana Jaya Line Kajang Line, Putrajaya line and KL Monorail. KLIA Ekspres and KLIA Transit Lines are not included.
  61. ^ The number is 138 if interchange stations (i.e. different sets of platforms) are counted as one, or 149 if stations are counted multiple times for each line.
  62. ^ Line 1 of the SITEUR system has some level crossings (with priority) and can be therefore be considered "light rail" instead of "metro".
  63. ^ Line 1 was opened in 1989.
  64. ^ Line 12 opened 2012.
  65. ^ The number is 163 if interchange stations (i.e. different sets of platforms) are counted as one, or 195 if stations are counted multiple times for each line.[300]
  66. ^ Note that:
    • "Operación": route length in active revenue and non-revenue service
    • "Servicio": route length in active revenue service
    • "Vuelta": track length in active revenue service
    • "Total": all track length in active revenue, maintenance and non-revenue service
    System length value derived from "RED Servicio" or net route length in active revenue service.
  67. ^ Some sections of the Rotterdam Metro (portions of Lines A, B, E) have some level crossings (with priority) and so could therefore be considered "light rail" instead of "metro".
  68. ^ Blue Line only. Red Line is a heavy rail commuter route.
  69. ^ a b These systems have similarities to light rail systems, because of the existence of a few road level crossings, but are listed since they are almost entirely separated from roads.

Out-of-station transfers at Banqiao and Xinpu - Xinpu Minsheng, which require leaving paid area, are counted as 2 stations each; transfer stations that provide cross-platform interchange are anyway counted as a single stations (four in all: Ximen, CKS Memorial Hall, Guting and Dongmen stations).[353][354]
  82. ^ Opening of line M4 extension to Kızılay station.
  83. ^ Extension to Gürsu.

  85. ^ London's Metropolitan Railway first opened for service in 1863, operating steam locomotive trains in cut and cover tunnels. It began operating as a modern metro when electric-propulsion trains began operating on the system's first deep-level tube line in 1890.
  86. ^ Includes both MBTA's heavy and light rail lines, as the light rail utilizes the same tracks and system as the heavy rail. Does not include the Silver Line, as in actuality this is a bus route. Heavy: Red Line, Orange Line, Blue Line Light: Green Line
  87. ^ The originally-elevated Orange Line opened in 1901, sharing the Tremont Street Subway that had opened in 1897 as an underground streetcar tunnel (for the light rail Green Line).

Ridership notes[edit]

  1. ^ This patronage figure is derived from OPAL trips (i.e. a tap-on/tap-off pair of the same OPAL card, including isolated tap-on or tap-off), non-OPAL ridership, as the users of some concessional cards or integrated tickets for events, is excluded.
  2. ^ a b c d e f g h i j k l m n o p q r All American Public Transportation Association (APTA) figures are derived from unlinked transit passenger trips (i.e. a transfer between two lines counts as two passenger trips, transferring twice counts as three trips, etc.).
  3. ^ This ridership figure is the sum of the "Heavy Rail (HR)" and "Intermediate Rail (IR)" figures for Toronto from the APTA Ridership report – in other words, this figure includes ridership on the Line 3 Scarborough (RT) line which APTA considers to be "Intermediate Rail (IR)".
  4. ^ Ridership of Guangfo Line counted in Guangzhou's ridership figures.
  5. ^ Note that:
    1. the ridership includes "Domestic Service", "Airport Express" and "Cross-boundary";
    2. "Intercity, Light Rail & Bus" and "High Speed Rail (HSR)" are excluded from the counts.
  6. ^ Figure extrapolated from 3.6 million average daily boardings
  7. ^ Does not include ridership on the RER/Transilien (941 million in 2021) and the Tramways (266 million).

  20. ^ a b c d e f g h i j k l m Compared to European or North American systems, Japanese rapid transit systems are generally neither thought of as metros nor as completely subterranean "subways" complicating whether only using the municipal subway statistic is accurate when comparing with other Metros around the world. As example Tokyo Metro and the Tokyo Metropolitan Bureau of Transportation's Toei Subway constitute only 22% of the 14.6 billion metropolitan railway ridership in Greater Tokyo (MLIT Yearly Statistics). In addition, when one considers intracity lines of JR East and private railway companies, Greater Tokyo (130 lines) has higher daily ridership than any other metropolitan area in the world with 14.6 billion passengers annually. The Osaka Municipal Subway also has only a minority share of all metropolitan railway ridership in Greater Osaka, constituting only 17.6% of Greater Osaka's 4.745 billion rail passengers annually in 2010. Including the municipal subway systems in both Kobe and Kyoto, the result still only comprises 22% of all rail travel in the Greater Osaka area with 1065.8 million passengers yearly (MLIT Yearly Statistics). For Greater Nagoya, the Nagoya Municipal Subway has only a minority share of all metropolitan railway ridership in Greater Nagoya constituting only 38% of Greater Nagoya's 1.095 billion rail passengers annually in 2010 (MLIT Yearly Statistics). For a complete list of urban rail systems in Japan with ridership statistics, see List of urban rail systems in Japan.
