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.

The North Bergen Yard is freight rail yard and intermodal terminal in North Bergen, New Jersey parallel to Tonnelle Avenue between 49th and 69th Streets. Located within the North Jersey Shared Assets Area, the facility is part of CSX Transportation (CSXT) and the origination point of its CSX River Subdivision at the southern end of the Albany Division. On its west side, the New York, Susquehanna and Western Railway (NYSW) runs the length of the yard and operates a bulk transloading operation immediately adjacent to it.
