On December 19, 2001, the Federal Transit Administration approved the start of preliminary engineering on a full-length Second Avenue Subway. The MTA's final environmental impact statement (FEIS) was approved in April 2004; this latest proposal is for a two-track line from 125th Street and Lexington Avenue in Harlem, down Second Avenue to Hanover Square in the Financial District. The final plan called for the full-length Second Avenue line to carry two services: the T, with a route emblem colored , as well as a rerouted Q train. Phase 1 rerouted the Q, the Broadway Express via the BMT 63rd Street Line and north along Second Avenue, to the Upper East Side at 96th Street. Phase 2 will extend the rerouted Q train to 125th Street and Lexington Avenue. In Phase Three, the new T train will run from 125th Street to Houston Street. The final phase will extend T train service from Houston Street to Hanover Square in Lower Manhattan.
