underground railway

City's buried trains

An underground railway is a rail transit system built beneath city streets, carrying passengers through tunnels.

The term is primarily British; Americans say subway.

The London Underground, opened in 1863, was the first.

Historically, the Underground Railway (or Railroad) was the network of secret routes and safe houses used by enslaved Black Americans escaping to freedom in the 19th century—neither underground nor a railway, but a covert system with stations, conductors, and passengers.
