181st Street (IRT Broadway–Seventh Avenue Line)

181st Street is a local station on the IRT Broadway–Seventh Avenue Line of the New York City Subway. Located at the intersection of St. Nicholas Avenue and 181st Street in Washington Heights, Manhattan, 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 station at 181st Street not yet open. The 181st Street station opened on May 30, 1906, and on this date express trains on the Broadway branch began running through to 221st Street, eliminating the need to transfer at 157th Street to shuttles.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 April 6, 1948, the stations from 103rd Street to Dyckman Street had their platform extensions opened, with the exception of 125th Street, which had its extension opened on June 11, 1948.
