The Amtrak Hudson Line, also known as the CSX Hudson Subdivision, is a railroad line owned by CSX Transportation and leased by Amtrak in the U.S. state of New York. The line runs from Poughkeepsie north along the east shore of the Hudson River to Rensselaer and northwest to Hoffmans via Albany and Schenectady along a former New York Central Railroad line. From its south end, CSX has trackage rights south to New York City along the Metro-North Railroad's Hudson Line. The Hudson Line junctions the Castleton Subdivision in Stuyvesant, Amtrak's Post Road Branch in Rensselaer and the Carman Subdivision in Schenectady. Its northwest end is at a merge with the Mohawk Subdivision.
