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.

The W Broadway Local is a rapid transit service of the New York City Subway's B Division. Its route emblem, or "bullet", is colored yellow since it uses the BMT Broadway Line in Manhattan.
