About Subway Systems

A rapid transit system is a public transport system in an urban area with high capacity, high frequency not needing timetables, is fast and is segregated from other traffic. Operating on an exclusive right of way, rapid transit systems are typically grade separated and located either in underground tunnels (subways) or elevated above street level (elevated transit line). Modern services on rapid transit systems are provided on designated lines between stations typically using electric multiple units on rail tracks, although some systems use guided rubber tyres, magnetic levitation, or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to avoid gaps. They are typically integrated with other public transport and often operated by the same public transport authorities, but does not exclude a fully segregated light rail transit. It is unchallenged in its ability to transport large amounts of people quickly over short distances with little use of land. Variations of rapid transit include people movers, small-scale light metro, and the commuter rail hybrid S-Bahn.
