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), métro or U-Bahn. 214 cities in 63 countries operate 950 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 oldest metro system. The Beijing Subway is the world's longest metro network at and the busiest one with annual ridership approximately 2.83 billion passenger trips. 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 (, 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".
