Located at the intersection of 34th Street and Seventh Avenue, it is served by the 1 and 2 trains at all times, and the 3 train at all times except late nights on weekdays. Connections are available to the LIRR, NJ Transit and Amtrak at Pennsylvania Station.History34th Street–Penn Station on the IRT Broadway–Seventh Avenue Line was opened on June 3, 1917, as part of an extension of the Interborough Rapid Transit Company, the dominant subway in Manhattan at the time, from Times Square–42nd Street to South Ferry. It was served by a shuttle train to Times Square until the rest of the extension opened a year later on July 1, 1918. This meant that the subway would be expanded down the Lower West Side to neighborhoods such as Greenwich Village and the western portion of Lower Manhattan.
