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 at all times between Ditmars Boulevard in Astoria, Queens, and Stillwell Avenue in Coney Island, Brooklyn via Astoria in Queens, Broadway in Manhattan, and Fourth Avenue/Sea Beach in Brooklyn; limited rush hour service originates and terminates at Third Avenue–149th Street in the Hub, Bronx instead of Ditmars Boulevard. On weekdays, the N runs express in Manhattan north of Canal Street, with weekday local service being provided by the W, which is internally staffed and scheduled as part of the N. On weekends, it makes all stops in Manhattan north of Canal Street.
Daytime service runs over the south side of the Manhattan Bridge and runs express along Fourth Avenue. During nights, the N serves all stops along its entire route, using the Montague Street Tunnel to travel between Manhattan and Brooklyn.
