subway systems
Urban rail networks
Subway systems are networks of underground railways that transport passengers through urban areas.
Major cities rely on them for mass transit: New York's subway system runs twenty-four hours a day, Tokyo's subway system moves millions of commuters daily.
The term encompasses the trains, tunnels, stations, and infrastructure as an integrated whole.
In British English, these are typically called the underground or tube.
