the digital signs of the R44s and R46s with any route and destination combination that could be used for the Broadway Line. The W label was first used in 2001, when the two tracks on the Manhattan Bridge's northern side, which connected to the IND Sixth Avenue Line, were closed for repairs. This required the suspension of Sixth Avenue service south of 34th Street–Herald Square as it used those tracks to travel to and from Brooklyn. The W service replaced the B on the BMT West End Line and BMT Fourth Avenue Line in Brooklyn, ran on the BMT Broadway Line in Manhattan and BMT Astoria Line in Queens. It replicated the route of the Brooklyn-Manhattan Transit Corporation (BMT)'s old 3 route, later named the , that operated from 1916 until 1967, when the B replaced it. The W also replicated the split in B service from 1986 to 1988, when the bridge's north tracks were first closed, although both halves of the route were labeled . 2001–2004 Plans for the W train were announced in late 2000, when the Metropolitan Transportation Authority announced that the Manhattan Bridge's south tracks would reopen and that the north tracks would be closed. W service began July 22, 2001. Service began operating between Coney Island and Astoria-Ditmars Boulevard, Queens, via the West End Local and Fourth Avenue Express in Brooklyn; the Manhattan Bridge south tracks; Broadway Express (switching to the local tracks to serve 49th Street) in Manhattan; and the 60th Street Tunnel and BMT Astoria Line in Queens. The W ran express on the Astoria Line during rush hours in the peak direction between 6a.m. and 9p.m., and local at all other times. Trains ran express to Manhattan between 6a.m. and 1p.m., and to Astoria from 1p.m. to 9p.m. Evening service terminated at 57th Street–Seventh Avenue in Manhattan (using the express tracks and bypassing 49th Street), while late night and weekend evening service operated as a shuttle within Brooklyn only, terminating at 36th Street during late nights and Atlantic Avenue–Pacific Street on weekends. After September 11, 2001, all Broadway Line service in Lower Manhattan was suspended due to extensive damage caused by the collapse of the World Trade Center. As a result, the entire N route was suspended, and W trains ran at all times between Ditmars Boulevard and Coney Island. It made all stops except in Brooklyn north of 36th Street.
