BMT Broadway Line

The BMT Broadway Line is a rapid transit line of the B Division of the New York City Subway in Manhattan, New York City, United States. As of 2010, it is served by three services, all colored sunflower yellow: the Q on the express tracks and the N R on the local tracks. The line is often referred to as the "N and R", since those were the only services on the line during the long years that the Manhattan Bridge south tracks were closed for rebuilding. The Broadway Line was built to give the Brooklyn Rapid Transit Company (later the Brooklyn–Manhattan Transit Corporation) access to Midtown Manhattan.

The line is named for its location under Broadway between Vesey Street and Seventh Avenue (Times Square). It also passes under Vesey Street, Whitehall Street, Trinity Place, and Church Street in Lower Manhattan, and Seventh Avenue, 59th Street, and 60th Street in Midtown. The local tracks stretch the entire length between the two East River tunnels: the Montague Street Tunnel to the BMT Fourth Avenue Line in Brooklyn and the 60th Street Tunnel to the BMT Astoria Line and 60th Street Tunnel Connection in Queens. Center express tracks exist between Canal Street and 57th Street, turning off at Canal Street to feed the south tracks on the Manhattan Bridge, and continuing north and east under Central Park as the BMT 63rd Street Line (presently unused, but planned to connect with the Second Avenue Subway). The Broadway Line was the only Manhattan outlet north of Delancey Street for the BMT's Brooklyn lines until 1967, when most BMT Brighton Line and BMT West End Line trains were moved to the IND Sixth Avenue Line via the new Chrystie Street Connection.
