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.
The River Subdivision is a railroad line owned by CSX Transportation in the U. Through mergers, leases, and takeovers, it became part of the New York Central Railroad and then Conrail in 1976.
The line runs from the North Bergen Yard in Hudson County, New Jersey north to Selkirk, New York The original line was opened in segments by a number of different companies from the 1860s to the opening of the full line in the 1880s, by which time it was known as the New York, West Shore and Buffalo Railway.
When the majority of Conrail was broken up in 1999, its River Line was assigned to CSX.
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 Selkirk, New York, carries strictly freight trains and runs mostly along the shoreline or paralleling closely to the west bank of the Hudson River.
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.
Also taking place at this same time, was the River Subdivision being extended south to QR 1.6, adding 5/10th of a mile to the route.
The section of track south of QR 1.6 at the south end of North Bergen Yard is now owned by Conrail Shared Assets Operation (CSAO) and is part of the North New Jersey Operational Area River Line.
As such, the River Subdivision now connects directly to the River Line at MP QR 1.6 and the first "Controlled Point" on the River Subdivision is now CP-QR 3.
