63rd Street Lines

The IND 63rd Street Line and BMT 63rd Street Line, also referred to as the 63rd Street Crosstown or Route 131-A, are two rapid transit lines of the IND and BMT divisions of the New York City Subway system. The two lines run under 63rd Street on the Upper East Side of Manhattan and meet at the Lexington Avenue–63rd Street station; two diamond crossover tracks just west of that station allow trains to switch between the two lines.
