The River Subdivision is a railroad line owned by CSX Transportation in the U.S. states of New Jersey and New York. The line runs from the North Bergen Yard in Hudson County, New Jersey north to Ravena, New York, along the alignment of the West Shore Railroad, a former New York Central Railroad line. History The original line was opened in segments by a number of different companies from the 1860s to the opening of the full line in 1883, by which time it was known as the New York, West Shore and Buffalo Railway. Through mergers, leases and takeovers, it became part of the New York Central Railroad; later Penn Central and then Conrail, in 1976. When the majority of Conrail was broken up in 1999, its River Line was assigned to CSX Transportation. Current operation The River Subdivision (also known as the River Sub or River SD) is a major north–south rail corridor located between North Bergen, New Jersey and Ravena, New York, carries strictly freight trains and runs mostly along the shoreline or paralleling closely the west bank of the Hudson River. The River Subdivision is part of the CSX Albany Division, which in turn is part of CSX's Northern Region of Operations. The CSX designated subdivision code for the River Subdivision is "RI", with the River Subdivision falling under the "NI" dispatchers desk since March 8, 2009. It had been part of the "NJ" dispatchers desk until this date. Mileposts and locations along the River Subdivision are denoted by the CSX milepost prefix: "QR". Trackage prior to 2008 Note: CP stands for Control Point, which denotes an interlocking, or the location of a track signal or other marker with which dispatchers can specify when controlling trains. Prior to July 1, 2008, the section of track from QR 2.1 north to CP-QR 7, a point located in Bogota, New Jersey, was originally part of the CSX Bergen Subdivision / Baltimore Division prior to 2008, while the River Subdivision began at CP-QR 7 and continued north to Selkirk. On July 1, 2008 (the effective date of CSX Albany Division Employees Timetable "ETT" #5), the segment from QR 2.1 to CP-QR 7 (which comprised the entire Bergen Subdivision); was incorporated into the River Subdivision, and the Bergen Subdivision was abolished.
