The Q Second Avenue/Broadway Express/Brighton Local 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 Q operates at all times between 96th Street in the Upper East Side of Manhattan and Stillwell Avenue in Coney Island, Brooklyn, via the BMT Broadway Line, the Manhattan Bridge and the BMT Brighton Line. Daytime service makes express stops in Manhattan and local stops in Brooklyn; late night service makes local stops along its entire route. Limited rush hour service operates locally in Brooklyn via the BMT Sea Beach Line and express via the BMT Fourth Avenue Line, but only in the northbound direction. 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 to Astoria–Ditmars Boulevard on the BMT Astoria Line from 2010 to 2016, Forest Hills–71st Avenue on the IND Queens Boulevard Line during temporary post-9/11 service reroutes, and 21st Street–Queensbridge on the IND 63rd Street Line until 2001. There was also a <Q> variant from 2001 to 2004, which ran express on the Brighton Line and terminated at Brighton Beach. On January 1, 2017, the Q was rerouted along the Second Avenue Subway.
