The River Line was a Conrail rail line located between Jersey City, New Jersey and Selkirk, New York, running along the west side of the Hudson Palisades and, after passing through a tunnel at Haverstraw, New York, along the west bank of the Hudson River. It was previously the New York Central's West Shore Railroad and Weehawken Branch. The River Line has since been split into several sections, following the 1999 division of Conrail assets between Norfolk Southern Railway and CSX Transportation. The majority of the line is now the CSX River Subdivision, which runs from Control Point 2 (CP2) at the North Bergen Yard in North Bergen, New Jersey to Selkirk. The portion south of CP2, including the Weehawken Tunnel, is now part of NJ Transit's Hudson–Bergen Light Rail. Freight trains continuing south of CP2 now use the Northern Running Track, a portion of a former Erie Railroad line that has been upgraded to handle the traffic. At Selkirk, the River Subdivision ends at the Castleton Subdivision, with the Port Subdivision continuing towards Albany. The Castleton Sub was built in 1924 as part of a bypass for through freight trains around Albany. Conrail's defunct River Line and Weehawken Branch The River Line began at CP Waldo, at a junction with the Passaic and Harsimus Line (P&H). The P&H Line runs west through what was the Pennsylvania Railroad's Bergen Hill Cut, just north of PATH, through a re-aligned Marion Junction. At CP Nave, the River Line junctioned with the National Docks Secondary, which still runs south on the east side of the Hudson Palisades, with the Nave-Croxton Running Track running west through the old Erie Railroad's Long Dock Tunnel. The junction only allowed trains coming to/from the south on the National Docks to continue to/from the north on the River Line. North of CP Nave, the River Line entered Hoboken; it is now used for the Hudson-Bergen Light Rail (HBLR) north of this point. The HBLR runs around the west and north sides of Hoboken and into Weehawken, where it turns west through a tunnel to CSX's North Bergen Yard, originally part of the New York Central's West Shore Railroad. From that point north, the River Line is still in use, but as CSX as the River Subdivision, north toward Albany, New York. The Weehawken Branch was just east of the River Line, from somewhere in Jersey City north of
