Montreal_Subdivision_(CSX)
The Montreal Subdivision is a railroad line owned by the St. Lawrence and Adirondack Railway[1] and Canadian National. Operations are currently by Canadian National. The line originally ran from Massena, New York, northeast to Kahnawake, Quebec,[2] along a former New York Central Railroad line. At its south end, the St. Lawrence Subdivision continues south; its north end was at Adirondack Junction, a junction with the Canadian Pacific Railway's Adirondack Subdivision, along which it had trackage rights north over the Saint-Laurent Railway Bridge into Montreal.[3][4]
