New York New Jersey Rail, LLC is a switching and terminal railroad that operates the only car float operation across Upper New York Bay between Jersey City, New Jersey and Brooklyn, New York. Since mid-November 2008, it has been owned by the Port Authority of New York and New Jersey, which acquired it for about $16 million as a step in a process that might see a Cross-Harbor Rail Tunnel completed.Since freight trains are not allowed in Amtrak's North River Tunnels, and the Poughkeepsie Bridge was closed in 1974, the ferry is the only freight crossing of the Hudson River south of the Alfred H. Smith Memorial Bridge, 140mi to the north of New York City, in a process known as the Selkirk hurdle. It is the last remaining car float operation in the Port of New York and New Jersey.
