The Q Second Avenue/Broadway Express/Brighton Local[3] 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 is a part of the BMT Broadway Line in Manhattan.
The Q operates 24 hours a day between 96th Street on the Upper East Side of Manhattan and Stillwell Avenue in Coney Island, Brooklyn. Daytime service makes express stops in Manhattan (between 57th Street–Seventh Avenue and Canal Street) and all stops in Brooklyn; overnight service makes all stops along the full route.[3]
The Q was originally the Brooklyn–Manhattan Transit Corporation (BMT)'s 1 service; beginning in 1920, it ran along the Brighton Line in Brooklyn and Broadway Line in Manhattan. In the past, the Q has run many different service patterns in Brooklyn, Manhattan and Queens, both local and express, including QB service on the Manhattan Bridge and QT service via the Montague Street Tunnel. From 1988 to 2001, Q service ran along the IND Sixth Avenue Line in Manhattan, with a bullet colored orange. The Q also ran in Queens at various points, including along the BMT Astoria Line to Astoria–Ditmars Boulevard on weekdays from 2010 to 2016, along the IND Queens Boulevard Line to Forest Hills–71st Avenue during temporary post-9/11 service reroutes, and along the IND 63rd Street Line to 21st Street–Queensbridge until 2001. There was also a <Q> variant from 2001 to 2004, which ran express on the Brighton Line and terminated at Brighton Beach due to construction on the north side of the Manhattan Bridge. On January 1, 2017, the Q was rerouted along the Second Avenue Subway.
