Bowling Green is a station on the IRT Lexington Avenue Line of the New York City Subway, located at Broadway and Battery Place (at the Bowling Green), in the Financial District of Manhattan. It is served by the ' train at all times and the ' train at all times except weekday late nights.Station layoutThe station has two tracks and two platforms in service: a center island platform that serves Brooklyn-bound trains, and a side platform that serves uptown trains. An abandoned and walled off island platform and track on the west side of the station were formerly used by the Bowling Green–South Ferry Shuttle to the inner platform at South Ferry. South of the station, the tracks diverge with one set entering the Joralemon Street Tunnel to Brooklyn. The line continues to the closed South Ferry inner loop station, which is used by the 5 train when it short turns at Bowling Green during evenings and weekends.HistoryWhen the station opened on July 10, 1905, there was as yet no IRT service to Brooklyn, and all Lexington Avenue trains terminated at South Ferry, using the outer-loop platform. After the Joralemon Street Tunnel opened in 1908, some Lexington Avenue trains continued to terminate at South Ferry, even during rush hours, while others went to Brooklyn. This service pattern was soon found to be inadequate for the high volume of Brooklyn riders.
