New York New Jersey Rail

New York New Jersey Rail, LLC (reporting mark NYNJ) 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, 140 miles (230 km) 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.

The railroad operates in two divisions, the Marine division and Port Jersey Rail division. Its switching operations on the New York side include a short spur north to Bush Terminal which runs through the Brooklyn Army Terminal complex and then through the center of First Avenue in Sunset Park. This spur is the last example of active street-running rail operations in New York City.
