215th Street is a local station on the IRT Broadway–Seventh Avenue Line of the New York City Subway. Located at the intersection of 215th Street and Tenth Avenue in the Manhattan neighborhood of Inwood, it is served by the 1 train at all times.HistoryThe West Side Branch of the first subway was extended northward to a temporary terminus of 221st Street and Broadway on March 12, 1906 with the first open station at Dyckman Street, as the stations at 168th Street, 181st Street, and 191st Street were not yet completed. This extension was served by shuttle trains operating between 157th Street and 221st Street until May 30, 1906 when express trains began running through to 221st Street.In 1948, platforms on the IRT Broadway–Seventh Avenue Line from 103rd Street to 238th Street were lengthened to 514 feet to allow full ten-car express trains to platform. Previously the stations could only platform six car local trains. The platform extensions were opened in stages. On July 9, 1948, the platform extensions at stations between 207th Street and 238th Street were opened for use at the cost of $423,000.
