The Whitehall and Plattsburgh Railroad opened from Fort Ticonderoga to Port Henry in 1870.

It became part of the New York and Canada Railroad, owned by the Delaware and Hudson Railway (D&H); its Albany–Rouses Point route (with a connection to Montreal) was completed in 1875.

It met the mainline just north of the new Montcalm Landing, which served ferries on Lake Champlain.

[8] The Laurentian continued to make a flag stop there until it was discontinued on April 30, 1971, upon the formation of Amtrak.

[9] Amtrak restored service on the line with the Adirondack on August 6, 1974; it served the shelter at the former Montcalm Landing location.
