Railway line in southwestern Quebec, Canada
The Rouses Point Subdivision is a railway line in southwestern Quebec. It runs north–south from the northern end of Canadian Subdivision, on the border with New York, to the St-Hyacinthe Subdivision, in the vicinity of Montreal. The oldest part of the line was the original main line of the Champlain and St. Lawrence Railroad, completed in 1836. Today, the Canadian National Railway owns the line. Amtrak's Adirondack operates over the full length, providing daily service between New York City and Montreal.
