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.

The River Subdivision is part of the CSX Albany Division, which in turn is part of CSX's Northern Region of Operations. 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. When the majority of Conrail was broken up in 1999, its River Line was assigned to CSX Transportation. Through mergers, leases and takeovers, it became part of the New York Central Railroad later Penn Central and then Conrail, in 1976.

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. 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. The River Subdivision is a railroad line owned by CSX Transportation in the U.S. Southbound train on River Subdivision at Newburghġ,435 mm ( 4 ft 8 + 1⁄ 2 in) standard gauge
