# 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, tubes, mass rapid transit (MRT), metrô or U-Bahn. As of 22 December 2024, 204 cities in 65 countries operate 891 metro lines.
The London Underground first opened as an underground railway in 1863 and its first electrified underground line, the City and South London Railway, opened in 1890, making it the world's first deep-level electric metro system. The Budapest 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. The Shanghai Metro is both the world's longest metro network at 808 kilometres (502 mi) and the busiest with the highest annual ridership reaching approximately 2.83 billion passenger trips. The Beijing Subway has the greatest number of stations, with 424. As of 2024, the country with the most metro systems is China, with 54 in operation, including 11 of the 12 longest networks in the world.

## 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". The terms heavy rail (mainly in North America) and heavy urban rail are essentially synonymous with the term "metro". Heavy rail systems are also specifically defined as an "electric railway".
The dividing line between the metro and other modes of public transport, such as light rail and commuter rail, is not always clear. The UITP only makes distinctions between "metros" and "light rail", whereas 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 with car traffic or use sections of track with level crossings across roads, metro systems tend to run on a grade-separated exclusive right-of-way with no access for 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

    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 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.
