New York New Jersey Rail is a Short Line Marine Railroad, established in 2005 with the acquisition of the New York Cross Harbor Railroad.  NYCH was formed in 1983, derived from the Brooklyn East District Terminal, Bush Terminal, and New York Dock railroads.

NYNJ Rail is unique as it provides the only remaining car float barge service on New York Harbor, connecting CSX, Norfolk Southern, ConRail in New Jersey with the New York & Atlantic Railway, South Brooklyn Railway (New York City Transit Authority) in New York.  The four and a half mile nautical journey is made several times per day, Monday through Friday.  In addition, NYNJ operates the fourteen track Greenville Yard in Jersey City, NJ and the expansive 65th Street yard and transload facility at the Brooklyn Army Terminal complex, in Brooklyn, NY.

In 2008, New York New Jersey Rail became a wholly owned unit of the Port Authority of New York and New Jersey.  The neighboring Port Jersey Railroad Company was also later acquired by the Port Authority, thus becoming a division of New York New Jersey Rail.

NYNJ Rail and PJR are customer service oriented and provides service Monday through Friday each week, with weekend service as required.
