Created by the Delaware & Hudson Railway (D&H) in 1881, the Napierville Junction Railway (NJR) was the D&H subsidiary in Canada. Its purpose was to provide the easiest and fastest line with minimal grades from Rouses Point, NY, to a point near Montreal (St. Constant Jct, QC, now Delson, QC), selected for its good connections to both of the city's main passenger terminals. Until the end of September 1917, the D&H used the connection over the Grand Trunk Railway's Victoria Bridge into Bonaventure Station. At Delson a junction also exists with the Canadian Pacific Railway (CPR) via the St. Lawrence Bridge into Windsor Station, used by the D&H from 1 October 1917 until the end of passenger service in 1971, and by Amtrak's Adirondack between 1974 and 1986.
