The City Hall station is a local station on the BMT Broadway Line of the New York City Subway in Tribeca and Civic Center, Manhattan. It is served by the R train all times except late nights, when the N train takes over service. The W train serves this station on weekdays only.

The BMT Broadway Line is a rapid transit line of the B Division of the New York City Subway in Manhattan. As of November 2016, it is served by four services, all colored yellow: the N and ​Q trains on the express tracks and the R and ​W trains on the local tracks during weekdays. The line is often referred to as the "N and R", since those were the only services on the line from 1988 to 2001, when the Manhattan Bridge's southern tracks were closed for rebuilding. The Broadway Line was built to give the Brooklyn Rapid Transit Company access to Midtown Manhattan.
