List of metro systems explained

See also: Rapid transit, List of suburban and commuter rail systems and List of tram and light rail transit 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, tubes or U-Bahn. 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 815.2km (506.5miles) 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. the country with the most metro systems is China, with 54 in operation (excluding Hong Kong and Macau).

Considerations

The International Association of Public Transport (French: 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".[4] [5] The terms heavy rail (mainly in North America) and heavy urban rail are essentially synonymous with the term "metro".[6] [7] [8] Heavy rail systems are also specifically defined as an "electric railway".[6] [7]

The dividing line between the metro and other modes of public transport, such as light rail[6] [7] and commuter rail,[6] [7] is not always clear. The UITP only makes distinctions between "metros" and "light rail",[4] the American Public Transportation Association (APTA) and Federal Transit Administration (FTA) distinguish all three modes.[6] [7] 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

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. 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.

    Under construction

    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 of Ivory Coast, Mongolia, Saudi Arabia and Serbia are currently constructing their first ever metro systems.

    388. 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.
