From top to bottom:Shanghai Metro is the metro system with the longest metro network and the highest annual ridership in the world.Beijing Subway has the most subway stations in the world. TheLondon Underground is the oldest metro system.
Thislist of metro systems includes electrifiedrapid transit train systems worldwide. In some parts of the world, metro systems are referred to assubways,undergrounds,tubes,mass rapid transit (MRT),metrô orU-Bahn. As of 1 April 2025,[update] 204 cities in 65 countries operate917metro lines.
TheLondon Underground first opened as an underground railway in 1863 and its first electrified underground line, theCity and South London Railway, opened in 1890,[1] making it the world's first deep-level electric metro system.[2] TheBudapest Millennium Underground Railway, which opened in 1896, was the world's first electric underground railway specifically designed for urban transportation and is still in operation today.[3] TheShanghai Metro is both the world's longestmetro network at 808 kilometres (502 mi) and the busiest with the highest annual ridership reaching approximately 2.83 billion passenger trips.[4][5] TheBeijing Subway has the greatest number of stations, with 424. As of 2024,[update] the country with the most metro systems is China, with 54 in operation, including 11 of the 12 longest networks in the world.
TheInternational 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 termsheavy 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]
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 orinter-city rail services. It is not relevant whether the system runs on steel wheels orrubber tyres, or if the power supply is from athird rail oroverhead 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 incorporatelight 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 asS-Bahn, suburban, regional or commuter rail. These are not included in this list. Neither arefunicular systems, orpeople 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'surban rail transit systems, or to establish a ranking.
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 systemsThe 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 formerlight rail orcommuter 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 bytransfer counted as one.
System length
Thesystem 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 issingle-track ormulti-track,single carriageway ordual 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 counttransferring between lines as multiple journeys, but others do not. Numbers may also be counted via different methods –faregates/turnstiles orlight barriers at entrances or vehicle doors being the most common but far from the only ones.
This list is sortable. Click on the icon in the column header to change sort key and sort order.Note: This list may not be fully representative, as yearly ridership numbers during theCOVID-19 pandemic are shown for some systems, while others have numbers from previous years.
The following is a list of new worldwide metro systems that are currently actively under construction. 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 ofIvory Coast andSerbia are currently constructing their first ever metro systems.
^Line A opened in stages between 1913 and 1914 by theAnglo-Argentine Tramways Company. Line A services continued as above-ground tram services through an access ramp atPrimera Junta Station. Subway-surface services into Line A ceased in 1926, with the line and itsrolling stock transitioned into pure rapid transit operation by 1927.[14][15]
^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.
^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 establishedVienna U-Bahn system (lines U4 and U6), operating as a modern metro.
^The number is 126 if interchange stations (i.e. different sets of platforms) are counted as one station, or 143 if all stations on all lines are counted multiple times for each line.
^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. Seethe history section of the Beijing Subway for details and references.
^The number of stations is 424 if the 98 (71 2-line, 9 3-line) interchange stations (i.e. different sets of platforms) are counted as one station, or 522 if all stations on all lines are counted multiple times for each line. Out-of-station interchange stations with same name (e.g.Dazhong Si), are counted as one station. Both counts exclude the 20 stations of theXijiao andLine T1 tram lines.[74]
^Length excludes theXijiao andLine T1 tram lines, which combined are 20.7 km long.
^Ridership data includes that ofXijiao andLine T1 tram lines.
^Opening of metroLine 1 and not light railLine 3, which opened in 2002.

^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.
^As of December 2021,[update] the number of stations is 507 if the 82interchange 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 408 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). Out-of-station interchange stations with same name (e.g.South Pudong Road), are counted as one station.[127]
^This figure excludesMaglev line andJinshan Railway, all of which often included in Shanghai Metro maps but not considered part of the system.

^Opening of theLänsimetro extension on 3 December 2022.
^The number is 321 if stations are counted individually. If transfers are counted by just adding up the number of stops in each line, the number is 405.
^The Green Line (Line 1), operated until 2011 byAthens–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.[197]
^The network consists of 257 stations if transfer stations are counted more than once. If transfer stations are counted only once, the result will be 232 stations.Ashok Park Main station, where the two diverging branches ofGreen Line share tracks/platforms, is anyway counted as a single station. Stations ofNoida Metro andGurgaon Metro are not counted. If they were counted, then there would be 289 total stations.[221][222]
^The lengths of theNoida Metro andGurgaon Metro are not counted with the Delhi Metro. If they were counted, the total length of the three systems would be 393.26 km (244.36 mi).
^abThe 43 km (27 mi) Line 1 of Karaj Metro (part of line 5 of Tehran metro) is acommuter rail line, and so is not included in the statistics here. If Line 1 is included, there would be 10 stations.
^abThere 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 acommuter 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.
^As of July 2023,[update] the number is 134 if the 9interchange stations (i.e. different sets of platforms) are counted multiple times, once for each line, while it is 113 if they are combined.[278][279]

^The Seoul Subway Lines 1-9 andSeoul Light Rapid Transit is actually operated by several different operators –Seoul Metro andSeoul Metro Line 9 Corporation (SLM9), plus through-operation services fromKorail – 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.
^abcSeoul'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).
^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.
^Line 1 of the SITEUR system has some level crossings (with priority) and can be therefore be considered "light rail" instead of "metro".
^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.[327]

^abcdefghijklmnopCompared to European or North American systems, Japaneserapid 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 exampleTokyo Metro and theTokyo Metropolitan Bureau of Transportation'sToei 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 ofJR 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. TheOsaka 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, theNagoya 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, seeList of urban rail systems in Japan.
^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 Seoulurban rail network are excluded.
