In March 1954, as part of a proposed $658 million construction program, the entire Pelham Line would have been connected to the Second Avenue Subway, with service being tripled on the Pelham Line. The IRT Pelham Line would be very easily converted to B Division standards, and connected to the Second Avenue line as Route 132–B of the 1968 Program for Action. IND Second Avenue Line trains would run east under 138th Street, then along the right-of-way of Amtrak's Northeast Corridor from 138th Street to a point near the Bruckner Expressway and Westchester Avenue as an express bypass of the Pelham line, after which the line would split into a Pelham branch and a Dyre Avenue branch. The Brook Avenue station just east of Third Avenue–138th Street on the IRT Pelham Line would be reconstructed to allow a cross-platform interchange. Further north, there would be a connection with the IRT Pelham Line near Westchester Avenue at the Whitlock Avenue station, and station platforms north to Pelham Bay Park would be narrowed and lengthened to accommodate the longer and wider B Division trains from the Second Avenue Subway. IRT local service on the Pelham Line would terminate at Hunts Point Avenue one stop south. This project would have helped relieve overcrowding on the IRT Lexington Avenue Line, which is the busiest line in the country.
