First subway of New York City. It had a single station located in the basement of the house located at the corner of Warren Street and Broadway. Passenger were carried in a car pushed forward by the pneumatic pressure generated by a huge fan. At the end of the tunnel, near Murray Street, the car stopped. The rotation of the fan was reversed and the car was "sucked" back to Warren Street station.

This subway was designed for experimental and promotional purposes. Alfred E. Beach intended to build a full scale network of pneumatic lines for public transportation in the already crowded Manhattan downtown.
