Metro/underground/rapid transit
A rapid transit Metro/underground/Elevated railway operated in an urban area with high capacity and frequency, and grade paration from other traffic. The systems are able to transport large amounts of people quickly over short distances with little land u. Variations of rapid transit include people movers, small-scale light metro and commuter rail hybrid S-Bahn.More than 160 cities have rapid transit systems, totalling more than 8000 km of track and 7000 stations,25cities have systems under construction.
