 The Program for Action proposed a Second Avenue line to be built in two phases : The first phase would start from 34th Street in Midtown , running up Second Avenue to 126th Street and continuing to the Bronx , with stops planned at 34th , 48th , 57th , 86th , 106th , and 125th Streets . The 48th Street stop would connect to a planned Metropolitan Transportation Center at Third Avenue and 48th Street , which would contain a new east side terminal for the Long Island Rail Road . The line included older proposals for connections to the Sixth Avenue and Broadway lines in Midtown via a new crosstown line , which would now be located on 63rd Street . The BMT 63rd Street Line would also include a connection allowing Second Avenue line trains to run to Queens . In the Bronx , the line would run along East 138th Street , with a cross @-@ platform transfer to Lexington Avenue Line trains at Brook Avenue on the IRT Pelham Line , which would be reconfigured . After that , Second Avenue line trains would use a new express bypass line along East 138th Street , and the former tracks of the New York , Westchester and Boston Railway ( NY & WB ) near the Bruckner Expressway . In Hunts Point , service would split into two branches . One branch would continue to use former NY & WB trackage to East 180th Street , at which point the line would connect to the IRT Dyre Avenue Line . A second branch would connect to the IRT Pelham Line in the vicinity of Whitlock Avenue station , another element from earlier plans . The first branch would take over all service on the Dyre Avenue Line , offering cross @-@ platform transfers to IRT White Plains Road Line trains at East 180th Street station , which would also be reconfigured . The second branch would take over service on the upper portion of the Pelham Line , between Whitlock Avenue and Pelham Bay Park . All stations on the Dyre Avenue and upper Pelham Lines would have platforms shaved back to accommodate larger B Division trains .
