ⓘ List of metro systems

Kiev Metro

The Kiev Metro is a rapid transit system that is the mainstay of Kievs public transport. It was the first rapid transit system in Ukraine and the third system in the Soviet Union, after Moscow and St. Petersburg. It has three lines with a total length of 67.56 kilometers and 52 stations. The system carries 1.331 million passengers daily, accounting for 46.7% of Kievs public transport load. In 2016, the metro carried 484.56 million passengers. The deepest station in the world, Arsenalna, is found on the system.

Almaty Metro

Almaty Metro is a rapid transit/metro system in Almaty, Kazakhstan. The first line of the system was opened on 1 December 2011, after more than 23 years of construction. A 2.9-kilometre, two-station extension of the Metro to Moskva station opened on 18 April 2015.

Barcelona Metro

The Barcelona Metro is an extensive network of rapid transit electrified railway lines that run mostly underground in central Barcelona and into the citys suburbs. It is part of the larger public transport system of Barcelona, the capital of Catalonia, Spain with unified fares under the Autoritat del Transport Metropolità scheme. As of 2014, the network is operated by two separate companies: Transports Metropolitans de Barcelona and Ferrocarrils de la Generalitat de Catalunya. It is made up of 12 lines, combining the lines owned by the two companies. Two lines, L9 and L10 are being built a ...

Belgrade Metro

The Belgrade Metro is a planned rapid transit system in Belgrade, the capital city of Serbia. Construction of the full metro system has been delayed repeatedly, mostly due to lack of funding. Belgrade has a population of over 1.6 million people, making it the largest city by population without a rapid transit system in Europe. Traffic congestion is common and poor infrastructure has put additional strain on the city, while the existing public transport system is incapable of efficiently shuttling passengers even from the suburbs to the downtown and back, let alone from one outlying end of ...

Budapest Metro

The Budapest Metro is the rapid transit system in the Hungarian capital Budapest. It is the oldest electrified underground railway system in continental Europe, and is only pre-dated by the London Underground. Budapests iconic Line 1 was completed in 1896.

MTR

The Mass Transit Railway is a major public transport network serving Hong Kong. Operated by the MTR Corporation Limited, it consists of heavy rail, light rail, and feeder bus service centred on an 11-line rapid transit network serving the urbanised areas of Hong Kong Island, Kowloon, and the New Territories. The system included 230.9 km of rail in 2018 with 163 stations, including 95 heavy rail stations and 68 light rail stops. The MTR is one of the most profitable metro systems in the world; it had a farebox recovery ratio of 187 per cent in 2015, the worlds highest. The MTR was ranked th ...

                                     

ⓘ 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, U-Bahnen or undergrounds. As of December 2017, 178 cities in 56 countries around the world host the approximately 180 metro systems that are listed here. The London Underground first opened as an "underground railway" in 1863 and its first electrified underground line opened in 1890, making it the worlds oldest metro system. The metro system with the longest route length is the Beijing Subway; the busiest one is the Beijing Subway; and the one with the most stations is the New York City Subway. China has the largest number of cities that have metro systems, with over 40 by 2019.

                                     

1. Considerations

The International Association of Public Transport LUnion 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 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 citys, regions, or countrys urban rail transit systems, or to establish a ranking.

                                     

2. 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 and the connecting 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.

4. Under construction

The following is a list of new worldwide metro systems that are currently actively under construction. Note that 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 is no metro systems currently in operation in the same city

The countries of Bangladesh, Ecuador, Ivory Coast, Nigeria, Pakistan, and Vietnam are currently constructing their first ever metro systems.
