N (New York City Subway service)

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

The N operates 24 hours daily between Ditmars Boulevard in Astoria, Queens, and Stillwell Avenue in Coney Island, Brooklyn; limited rush hour service originates and terminates at 96th Street on the Upper East Side of Manhattan instead of Ditmars Boulevard. Weekday daytime service makes all stops in Queens and express stops in Manhattan, and in Brooklyn (between Atlantic Avenue and 59th Street), bypasses DeKalb Avenue and operates via the Manhattan Bridge, bypassing the Financial District of Lower Manhattan. Weekend daytime service is the same as weekday daytime service, except trains make all stops in Manhattan between 34th and Canal Streets. Overnight service makes all stops along the full route, serves the Financial District and uses the Montague Street Tunnel to travel between Manhattan and Brooklyn instead of the Manhattan Bridge, and stops at DeKalb Avenue.

The N was originally the Brooklyn–Manhattan Transit Corporation's 4 service, running along the BMT Sea Beach Line to the Manhattan Bridge. The 4 used the BMT Nassau Street Line in Lower Manhattan from 1915 to 1917, after which it ran express on the BMT Broadway Line. The 4 became the N in 1961. The N ran local in Queens along the IND Queens Boulevard Line to Forest Hills–71st Avenue from 1976 until 1987, when it switched terminals with the R. From 1986 to 2004, reconstruction on the Manhattan Bridge forced the N to run local on the Broadway Line via the Montague Street Tunnel.
