The Pennsylvania Railroad Station was the intermodal passenger terminal for the Pennsylvania Railroad's (PRR) vast holdings on the Hudson River and Upper New York Bay in Jersey City, New Jersey. By the 1920s the station was called Exchange Place in response to local nomenclature. The rail terminal and its ferry slips were the main New York City station for the railroad until the opening in 1910 of New York Penn Station, made possible by the construction of the North River Tunnels.
