This list of metro systems includes electrified
rapid transittrain systems worldwide. In some cases, metro systems are referred to as subways, U-Bahns or undergrounds. As of October 2014[update], 148 cities[1] in 55 countries around the world host the approximately 160 metro systems that are listed here. The earliest metro system, the
London Underground, first opened as an "underground railway" in 1863;[4] its first electrified underground line opened in 1890,[4] making the London Underground the world's first metro system.[3] The metro system with the longest
route length in the world is the
Shanghai Metro;[1][2] the busiest one is the
Beijing Subway;[2] and the one with the most stations is the
New York City Subway.[2]
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".[5][6] The terms Heavy rail (mainly in North America) and heavy urban rail are essentially synonymous with the term "metro".[7][8][9] Heavy rail systems are also specifically defined as an "electric railway".[7][8]
The dividing line between metro and other modes of
public transport, such as
light rail[7][8] and
commuter rail,[7][8] is not always clear, and while UITP only makes distinctions between "metros" and "light rail",[5] the U.S.'s APTA and FTA distinguish all three modes.[7][8] 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. And 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. Furthermore, most metro systems do not share tracks with freight trains or
inter-city rail services. It is however 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 match the technical level and 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 rapid transit systems, or to establish a ranking. Doing so would in many cases lead to a gross misrepresentation.
The most common English name of the metro system (and the connecting Wiki page for that system).
Year opened
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 (e.g. electrified) is the one listed.
Year of last expansion
The last time the metro system was expanded in terms of the system length or number of stations.
Stations
The number of stations in the metro network, as quoted by the system's operating company.
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.
The following is a list of new worldwide metro systems that are currently actively under (heavy) construction. Note that in some cases it is not clear (mainly due to lack of information), if the system will be considered a full metro system once it begins operational service. Only cities which currently do not have metro systems in operation should be included.
^The Beijing Subway's first line began trial operations on October 1, 1969. It opened to revenue service under trial operations on January 15, 1971. Initially, only members of the public with credential letters from their work units could purchase tickets, but this restriction was removed on December 27, 1972. The subway line passed its final inspections and ended trial operations on September 15, 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.
^
As of December 28, 2013, the
number of unique stations in operation in the Beijing Subway is 232. The unique station count treats the multiple platforms of a station complex as one station. If each station complex's platforms are counted as separate stations, then the total number of stations in operation as of February 15, 2014 would be 262.
The unique station count of 232 excludes: the
Erligou Station on Line 6, the
Andelibeijie and
National Art Museum Stations on Line 8, the
Wangjing East Station on Line 15 and the
Yizhuang Railway Station on the Yizhuang Line, which were not in use as of December 28, 2013. Also excluded are the three
restricted stations of Line 1, which are no longer used.
The total station count of 262 excludes the stations listed above and treats the
Gongyixiqiao Station as two stations, as the southern terminus for Line 4 and northern terminus for the Daxing Line, even though through-train service have effectively transformed the two lines into a single line for which the Gongyixiqiao Station is not a terminus but a single station.
^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.
^Note that:
1) Annual ridership is derived from the sum of each month's "Monthly Total" for each year
2) The ridership includes "MTR Lines", "Airport Express" and "Cross-boundary".
3) "Intercity, Light Rail & Bus" are excluded from the counts.
If interchange stations are counted as a single station, there are 263 stations.
If interchange stations are counted as multiple stations, there are 312 stations.
If interchange stations are counter as multiple stations, but shared tracks/platforms on Lines 3 and 4 are counted as a single station, there are 303 stations.
^The U3 extension from Olympia-Einkaufszentrum (OEZ) to Moosach.
^The official source states there are 100 stations in Munich U-Bahn system, but notes that four connecting/transfer stations have been counted twice; thus, there are 96 stations counting all stations once.
^The U3 extension from Maxfeld to Friedrich-Ebert-Platz.
^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.

^The Seoul Subway (Lines 1-9) is actually operated by three different operators – Seoul Metro, Seoul Metropolitan Rapid Transit Corporation (SMRT), and Seoul Metro Line9 Corporation. But because all of these lines are owned by the City Government of Seoul, they are counted together here in the table 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 468.9 km (291.4 mi), and it would serve a grand total of 377 stations.
^Includes the
Bundang Line (52.9 km, 36 stations), Korail portions of
Seoul Subway Line 3 (Islan Line: 19.2 km, 9 stations) and
Seoul Subway Line 4 (Gwacheon Line: 11.8 km, 8 stations; and
Ansan Line: 27.6 km, 14 stations), and the
Suin Line (non-Ansan portion) (13.1 km, 8 stations).
^There are 147 stations on the network map, counting transfer stations as one. The sum of the number of the stations for all lines is 195.
^Line 50, 53, and 54 are rapid transit. The figures provided exclude the portion of the Amstelveen Line (Line 51) that operates as
light rail.
^Some sections of the Rotterdam Metro (portions of Lines A and B) have some level crossings (with priority), and use overhead wires instead of a third rail (as most of the system does), and so could therefore be considered "
light rail" instead of "
metro".
^These systems have similarities to
light rail systems, because of existence of road level crossings, but are listed since there are almost entirely separated from roads.
^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.
^TMB-operated lines L1-L5 and L9-L11 only.
FGC-operated lines L6-L8 share track with other FGC commuter lines, and thus don't qualify as metro-standards lines.
^Currently operational metro standards lines, M1–M4 and M6, only included. All other Istanbul lines or segments are either
Tram or
Commuter rail, or are under construction, and so are not included here.
^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.
^The
Red,
Orange, and
Blue lines of the subway are rapid transit. The originally-elevated Orange Line opened in 1901, sharing the
Tremont Street Subway that opened in 1897 as an underground streetcar tunnel (for the
light railGreen Line).

The Loop", when the system became unified and electrified.
^This figure comes from the sum of the following figures from the accompanying reference (i.e.
"Facts at a Glance".

^Rapid transit portion of L.A. Metro Rail only:
Red and
Purple lines. All other L.A. Metro Rail lines are
Light rail, and are not included here.
^This was the date of the last extension to the Red Line in the rapid transit portion of Los Angeles' Metro Rail.
^First regular elevated railway service, originally cable hauled, began in 1868. Elevateds converted to steam power in 1870, electrified by 1903. The first section of electrified subway opened in 1904.
^The total number of stations is 472, but with transfer stations counted only once, the number is 423 (including the temporarily closed
Cortlandt Street – World Trade Center station).
^While the line opened as a railroad in 1860, it was not until 1925 that rapid transit equipment would be operated here.
^Manhattan Transfer and Park Place stations opened in 1911, though these stations were closed and replaced with Harrison and Newark stations, respectively, in 1937.
^The opening of the Bridge Line, the precursor rapid transit line to PATCO's, which ran between 8th Street in Philadelphia and Broadway in Camden. The current PATCO Speedline, with service through to Lindenwold, opened in 1969.

abcdefghijklmCompared 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.
^Seoul Subway Lines 1 to 9: 2,620 million (2013) (
Seoul Metropolitan Government Statistics) This figure counts only gate-passers, so it only includes SMRT, Seoul Metro, and Seoul Subway Line 9 riders. Many other lines such as those operated by
Korail (1,027 million (2012) (
Korail)),
AREX, as well as the
Shinbundang Line function as separate metro systems within the greater Seoul rapid transit network and are excluded (often due to unavailable data).

^Rapid transit portion of L.A. Metro Rail only:
Red and
Purple lines. All other L.A. Metro Rail lines are
Light rail, and are not included here.
^This was the date of the last extension to the Red Line in the rapid transit portion of Los Angeles' Metro Rail.
^First regular elevated railway service, originally cable hauled, began in 1868. Elevateds converted to steam power in 1870, electrified by 1903. The first section of electrified subway opened in 1904.
^The total number of stations is 472, but with transfer stations counted only once, the number is 423 (including the temporarily closed
Cortlandt Street – World Trade Center station).
^While the line opened as a railroad in 1860, it was not until 1925 that rapid transit equipment would be operated here.
^Manhattan Transfer and Park Place stations opened in 1911, though these stations were closed and replaced with Harrison and Newark stations, respectively, in 1937.
^The opening of the Bridge Line, the precursor rapid transit line to PATCO's, which ran between 8th Street in Philadelphia and Broadway in Camden. The current PATCO Speedline, with service through to Lindenwold, opened in 1969.
^Statistics presented here for the
Caracas Metro include the
Los Teques Metro which functions as effectively a subsidiary and extension of the Caracas Metro.

Ridership notes
^This ridership figure includes the
Premetro (Line E2) ridership in the total.

abcdefghijklmAll
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.).
^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)".
^Does not include ridership on the
RER (1211 million),
Transilien (1095 million), and the
Tramways (223 million).
^Figure extrapolated from 50 million passengers over the first 6 months of operation.

abcdefghijklmCompared 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.
^Seoul Subway Lines 1 to 9: 2,620 million (2013) (
Seoul Metropolitan Government Statistics) This figure counts only gate-passers, so it only includes SMRT, Seoul Metro, and Seoul Subway Line 9 riders. Many other lines such as those operated by
Korail (1,027 million (2012) (
Korail)),
AREX, as well as the
Shinbundang Line function as separate metro systems within the greater Seoul rapid transit network and are excluded (often due to unavailable data).
