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".{{cite web |url=http://ftp.uitp.org/ftproot/euroteam/YVA/URP_Fundamental_Requirements_EN.pdf |title=Recommended basic reference for developing a minimum set of standards for voluntary use in the field of urban rail, according to mandate M/486 |publisher=UITP (L'Union internationale des transports publics/International Association of Public Transport) |year=2011 |access-date=2014-02-15 |url-status=dead |archive-url=https://web.archive.org/web/20140222133945/http://ftp.uitp.org/ftproot/euroteam/YVA/URP_Fundamental_Requirements_EN.pdf |archive-date=22 February 2014 }}{{cite web |url=http://www.urbanrail.net/about.htm#definition |title=What is a metro? |author=Schwandl, Robert |website=UrbanRail.Net |year=2007 |access-date=2008-01-14}} The terms heavy rail (mainly in North America) and heavy urban rail are essentially synonymous with the term "metro".{{cite web |url=https://www.apta.com/research-technical-resources/transit-statistics/public-transportation-fact-book/fact-book-glossary/#8 |title=Fact Book Glossary – Mode of Service Definitions |publisher=American Public Transportation Association |access-date=2013-11-12}}{{cite web | url = http://www.ntdprogram.gov/ntdprogram/Glossary.htm | title = National Transit Database Glossary | publisher = U.S. Department of Transportation Federal Transit Administration | date = 18 October 2013 | access-date = 2013-11-12 |url-status=dead | archive-url = https://web.archive.org/web/20131113002142/http://www.ntdprogram.gov/ntdprogram/Glossary.htm | archive-date = 13 November 2013 | df = dmy-all }}{{cite web |url=https://trl.co.uk/sites/default/files/TRL593%20-%20The%20Demand%20for%20Public%20Transport.pdf |title=The demand for public transport: a practical guide |year=2004 |editor-last=Balcombe |editor-first=R. |publisher=Transport Research Laboratory |page=6 |access-date=2008-03-27 |archive-date=12 July 2018 |archive-url=https://web.archive.org/web/20180712021901/https://trl.co.uk/sites/default/files/TRL593%20-%20The%20Demand%20for%20Public%20Transport.pdf |url-status=dead }} Heavy rail systems are also specifically defined as an "electric railway".

The dividing line between metro and other modes of public transport, such as light rail and commuter rail, is not always clear, and while UITP only makes distinctions between "metros" and "light rail", the American Public Transportation Association (APTA) and Federal Transit Administration (FTA) distinguish all three modes. 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 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

File:World metro system cities.png

File:World Metro systems.svg

; 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: 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.

| 1971The 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.

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 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 ([http://www.mlit.go.jp/kisha/kisha07/01/010330_3/01.pdf 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 ([http://www.mlit.go.jp/kisha/kisha07/01/010330_3/01.pdf 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 ([http://www.mlit.go.jp/kisha/kisha07/01/010330_3/01.pdf MLIT Yearly Statistics]).

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".{{cite web |url=http://ftp.uitp.org/ftproot/euroteam/YVA/URP_Fundamental_Requirements_EN.pdf |title=Recommended basic reference for developing a minimum set of standards for voluntary use in the field of urban rail, according to mandate M/486 |publisher=UITP (L'Union internationale des transports publics/International Association of Public Transport) |year=2011 |access-date=2014-02-15 |url-status=dead |archive-url=https://web.archive.org/web/20140222133945/http://ftp.uitp.org/ftproot/euroteam/YVA/URP_Fundamental_Requirements_EN.pdf |archive-date=22 February 2014 }}{{cite web |url=http://www.urbanrail.net/about.htm#definition |title=What is a metro? |author=Schwandl, Robert |website=UrbanRail.Net |year=2007 |access-date=2008-01-14}} The terms heavy rail (mainly in North America) and heavy urban rail are essentially synonymous with the term "metro".{{cite web |url=https://www.apta.com/research-technical-resources/transit-statistics/public-transportation-fact-book/fact-book-glossary/#8 |title=Fact Book Glossary – Mode of Service Definitions |publisher=American Public Transportation Association |access-date=2013-11-12}}{{cite web | url = http://www.ntdprogram.gov/ntdprogram/Glossary.htm | title = National Transit Database Glossary | publisher = U.S. Department of Transportation Federal Transit Administration | date = 18 October 2013 | access-date = 2013-11-12 |url-status=dead | archive-url = https://web.archive.org/web/20131113002142/http://www.ntdprogram.gov/ntdprogram/Glossary.htm | archive-date = 13 November 2013 | df = dmy-all }}{{cite web |url=https://trl.co.uk/sites/default/files/TRL593%20-%20The%20Demand%20for%20Public%20Transport.pdf |title=The demand for public transport: a practical guide |year=2004 |editor-last=Balcombe |editor-first=R. |publisher=Transport Research Laboratory |page=6 |access-date=2008-03-27 |archive-date=12 July 2018 |archive-url=https://web.archive.org/web/20180712021901/https://trl.co.uk/sites/default/files/TRL593%20-%20The%20Demand%20for%20Public%20Transport.pdf |url-status=dead }} Heavy rail systems are also specifically defined as an "electric railway".

The dividing line between metro and other modes of public transport, such as light rail and commuter rail, is not always clear, and while UITP only makes distinctions between "metros" and "light rail", the American Public Transportation Association (APTA) and Federal Transit Administration (FTA) distinguish all three modes. 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 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

File:World metro system cities.png

File:World Metro systems.svg

; 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: 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.

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 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 ([http://www.mlit.go.jp/kisha/kisha07/01/010330_3/01.pdf 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 ([http://www.mlit.go.jp/kisha/kisha07/01/010330_3/01.pdf 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 ([http://www.mlit.go.jp/kisha/kisha07/01/010330_3/01.pdf MLIT Yearly Statistics]).

| Seoul SubwayThe 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're counted together as one system.Seoul's Metropolitan Subway system can also be viewed as a comprehensive metro network made up of multiple owned/operated metro systems.

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".{{cite web |url=http://ftp.uitp.org/ftproot/euroteam/YVA/URP_Fundamental_Requirements_EN.pdf |title=Recommended basic reference for developing a minimum set of standards for voluntary use in the field of urban rail, according to mandate M/486 |publisher=UITP (L'Union internationale des transports publics/International Association of Public Transport) |year=2011 |access-date=2014-02-15 |url-status=dead |archive-url=https://web.archive.org/web/20140222133945/http://ftp.uitp.org/ftproot/euroteam/YVA/URP_Fundamental_Requirements_EN.pdf |archive-date=22 February 2014 }}{{cite web |url=http://www.urbanrail.net/about.htm#definition |title=What is a metro? |author=Schwandl, Robert |website=UrbanRail.Net |year=2007 |access-date=2008-01-14}} The terms heavy rail (mainly in North America) and heavy urban rail are essentially synonymous with the term "metro".{{cite web |url=https://www.apta.com/research-technical-resources/transit-statistics/public-transportation-fact-book/fact-book-glossary/#8 |title=Fact Book Glossary – Mode of Service Definitions |publisher=American Public Transportation Association |access-date=2013-11-12}}{{cite web | url = http://www.ntdprogram.gov/ntdprogram/Glossary.htm | title = National Transit Database Glossary | publisher = U.S. Department of Transportation Federal Transit Administration | date = 18 October 2013 | access-date = 2013-11-12 |url-status=dead | archive-url = https://web.archive.org/web/20131113002142/http://www.ntdprogram.gov/ntdprogram/Glossary.htm | archive-date = 13 November 2013 | df = dmy-all }}{{cite web |url=https://trl.co.uk/sites/default/files/TRL593%20-%20The%20Demand%20for%20Public%20Transport.pdf |title=The demand for public transport: a practical guide |year=2004 |editor-last=Balcombe |editor-first=R. |publisher=Transport Research Laboratory |page=6 |access-date=2008-03-27 |archive-date=12 July 2018 |archive-url=https://web.archive.org/web/20180712021901/https://trl.co.uk/sites/default/files/TRL593%20-%20The%20Demand%20for%20Public%20Transport.pdf |url-status=dead }} Heavy rail systems are also specifically defined as an "electric railway".

The dividing line between metro and other modes of public transport, such as light rail and commuter rail, is not always clear, and while UITP only makes distinctions between "metros" and "light rail", the American Public Transportation Association (APTA) and Federal Transit Administration (FTA) distinguish all three modes. 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 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

File:World metro system cities.png

File:World Metro systems.svg

; 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: 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.

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 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 ([http://www.mlit.go.jp/kisha/kisha07/01/010330_3/01.pdf 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 ([http://www.mlit.go.jp/kisha/kisha07/01/010330_3/01.pdf 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 ([http://www.mlit.go.jp/kisha/kisha07/01/010330_3/01.pdf MLIT Yearly Statistics]).
