metro systems

Underground transit networks

Metro systems are urban rail transit networks, typically underground or elevated, designed to move large numbers of passengers within cities.

The term encompasses subways, undergrounds, and rapid transit systems: Paris has one of the oldest metro systems in Europe.

Metro systems usually feature dedicated tracks, frequent service, and multiple stops across a metropolitan area.
