マンハッタン橋
The current set of four services — N, Q, R, and W — started using the line since July 22, 2001, when the south tracks on the Manhattan Bridge reopened and the Broadway B and D services were discontinued. At this time, the north-side tracks were closed. Originally, the N was local via the Montague Street Tunnel and the BMT Sea Beach Line, and the W was express via the Manhattan Bridge and the BMT West End Line. On February 22, 2004, when the north tracks reopened, the N became express via the Manhattan Bridge and the W was short-turned at Whitehall Street, its Brooklyn section being replaced by the D.
