List of metro systems

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, U-Bahn, or by various acronyms such as MRT. As of 28 August 2023, 195 cities in 62 countries have a metro system.

For light metro systems, see Medium-capacity rail system § List of systems.

The Shanghai Metro is the metro system with the longest route length, and the highest annual ridership. The New York City Subway (middle) has the most stations in the world. The London Underground (bottom) is the oldest 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 Shanghai Metro is the world's longest metro network at 803 kilometres (499 mi) and 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 45 in operation.

Considerations

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 the 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 of 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
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.

List

Note: This list may not be fully representative, as yearly ridership numbers during the COVID-19 pandemic are shown for some systems, while others have numbers from previous years.

Under construction

The following is a list of new worldwide metro systems that are currently actively under construction. Note that in some cases it is not clear if the system will be considered a full metro system once it begins operational service. Only metro systems under construction are listed where there are no metro systems currently in operation in the same city.

The countries of Ivory Coast and Serbia are currently constructing their first ever metro systems.

Notes

System notes
  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 Metrofor's rapid transit line only: Linha Sul (South Line).
  7. Includes Metrorec's rapid transit lines only: Linha Centro (Center Line) and Linha Sul (South Line).
  8. 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.
  9. The number is 370 if the 78 (69 2-line, 9 3-line) interchange stations (i.e. different sets of platforms) are counted as one station, or 457 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.[71]
  10. Length excludes the Xijiao and Line T1 tram lines.
  11. Opening of metro Line 1 and not light rail Line 3, which opened in 2002.
  12. There are 100 stations if the station on 3 light rail line are counted
  13. There are 111.2 km (69.1 mi) of rail length if 3 light rail line are counted
  14. There are 284 stations if the 46 (41 2-line, 5 3-line) interchange stations (i.e. different sets of platforms) are counted as one station. There are 335 stations if all stations on all lines are counted multiple times for each line. Excludes light rail line T2.
  15. There are 241 stations if the 35 (31 2-line, 4 3-line) interchange stations (i.e. different sets of platforms) are counted as one station. There are 279 stations if all stations on all lines are counted multiple times for each line.
  16. First line of Foshan Metro serves two cities – Foshan and Guangzhou
  17. The 4.0-km long APM line is not included here, because it is a people mover.
  18. There are 254 stations if the 38 (35 2-line, 3 3-line) interchange stations (i.e. different sets of platforms) are counted as one station. There are 295 stations if all stations on all lines are counted multiple times for each line.
  19. 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.
  20. 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.
  21. 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).[121]
  22. This figure excludes Pujiang line, Maglev line and Jinshan Railway, both often included in Shanghai Metro maps but not considered part of the system.
  23. As of 28 December 2022, there are 369 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 303 stations if they are counted as one station.
  24. There are 254 stations if the 34 (31 2-line, 3 3-line) interchange stations (i.e. different sets of platforms) are counted as one station. There are 291 stations if all stations on all lines are counted multiple times for each line.
  25. Extension of Line A from Itagüí south to La Estrella.
  26. Line A was extended in April 2015.
  27. Opening of the Länsimetro extension on 3 December 2022.
  28. Opening of Toulouse Metro Line B.
  29. Opening of State University Station on Saburtalo Line.
  30. The U3 extension from Olympia-Einkaufszentrum (OEZ) to Moosach.
  31. 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.[185][186]
  32. 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.[185]
  33. 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]
  34. 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 392.44 km (243.85 mi).
  35. Qahramanan and Amirkabir stations open
  36. Opening of metro-standards Line 2.
  37. 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 8 stations.
  38. Opening of metro-standards Line 2.
  39. There are 162 stations if interchange stations are counted once, and 191 stations if they are counted multiple times. The 109.5 km (68.0 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 279.1 km (173.4 mi), and there would be 162 unique stations, and 191 total stations.
  40. Opening of Cibali station in July
  41. 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.[252][253]

  51. 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.
  52. 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).
  53. Includes Korail portions of Seoul Subway Line 3 (Ilsan Line: 19.2 km, 10 stations) and Seoul Subway Line 4 (Gwacheon, Ansan, Jinjeop Lines: 55.3 km, 27 stations), and the Suin–Bundang Line (108.1 km, 63 stations in part shared with the Ansan Line).

    • "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.
  62. 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".
  63. 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.
  64. The first underground portion was opened in 1928, but that was a tram line. One surface line has origins from 1898. System opened as a full Metro in 1966.

  70. TMB-operated lines L1-L5 and L9-L11 only. FGC-operated lines L6-L8 share track with other FGC commuter lines, and thus do not qualify as metro-standards lines.
  71. There are 132 stations in the Barcelona Metro if interchange stations are counted once, while there are 163 if they are counted multiple times.
  72. CTB-owned and "Metro Bilbao S.A."-operated line 1 and Line 2 only.
  73. Including TFM, MetroSur and other suburban lines, but not the three Metro Ligero de Madrid lines which are light rail.
  74. The first line, later known as Green Line, was opened by stages during the 1950s, partly converting to metro operations prior rapid tram alignments. These included the oldest tunnel, built in 1933, which name (Tunnelbana) and symbol were bequeathed to the new system.
  75. The Lausanne Metro has two lines: Line M1 is light rail, while Line M2 is rapid transit. The stats listed are for Line M2 only.

  80. 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.
  81. Includes MBTA's rapid transit lines only: Red Line, Orange Line and Blue Line.
  82. 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).
  83. Dated from the opening of "The Loop", when the system became unified and electrified. However, the L first was electrified in 1895, when the Metropolitan West Side Elevated opened. The South Side Main Line opened on June 6th, 1892
  84. This figure comes from the sum of the following figures from the accompanying reference (i.e. "Facts at a Glance". Chicago Transit Authority. December 2012. Retrieved 21 July 2013.): 35.8 miles of elevated route, 35.0 miles at grade level, 20.6 miles on embankments, and 11.4 miles of subway.

  88. The number is 424 if interchange stations (i.e. different sets of platforms) are counted as one station, or 472 if all stations on all lines are counted multiple times for each line.[390]
  89. While the line opened as a railroad in 1860, it was not until 1925 that rapid transit equipment would be operated here.
  90. The last completely new stations were the current Newark and Harrison stations, which respectively replaced the Park Place and Harrison stations on a different alignment in 1937. According to PATH, its newest station is World Trade Center, which was completed in 2015 but replaced a previous station on the same site.
  91. Includes SEPTA's rapid transit lines only: Broad Street Line (Orange Line), Market–Frankford Line (Blue Line) and Norristown High Speed Line.

Ridership notes
  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. 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. Counted in with 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).
  8. This ridership figure is the sum of the two "Μετρό" figures (Γ1 line, or "Ηλεκτρικός", formerly ran by IASA and Γ2 - Γ3 lines, formerly ran by AMEL) from the OAΣA's 2018 Activity Report.

  10. Figure extrapolated from 42 000 average daily boardings
  11. 56.4 million including 4 Funicular lines
  12. 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.
  13. This ridership figure includes the Busan-Gimhae Light Rail Transit ridership in the total.
  14. This figure counts only gate-passers, so it only includes Seoul Metro and Seoul Subway Line 9 riders. Other lines that function as separate systems within the greater Seoul urban rail network are excluded.
  15. Ridership is based on unlinked passenger trips (i.e. a transfer between two lines counts as two trips, transferring between three lines counts as three trips, etc.).
  16. This ridership figure is the sum of the total annual trips (수송인원, boarding and transfer passengers) on the five lines (Gwacheon/Ansan, Bundang, Ilsan and Suin) from the accompanying reference. Overall, Korail metro/commuter lines in Seoul Metropolitan Area (SMESRS) carry 1,189 million passengers annually (2019).
  17. This ridership figure is the sum of the total annual trips (수송인원, boarding and transfer passengers) on the two sections (Phase 1 and Phase 2) of the line, from the accompanying reference.
  18. This figure includes in full the ridership on Amstelveen Line until March 2019, when route 51 was curtailed at Zuid Station.
  19. This figure is the sum of the passenger ridership on the two LRTA lines, L1 and L2, from the accompanying reference; it is based on unlinked passenger trips (i.e. a transfer between two lines counts as two trips, etc.).
  20. Figure extrapolated from 2,745,000 average daily ridership.
  21. Figure extrapolated from 1 265 900 average daily boardings.
  22. Ridership figure is for rapid transit Line M2 only; ridership on the light rail M1 line is excluded.
