The Lake Champlain and St. Lawrence Junction Railway commenced operation in the Richelieu River valley between Stanbridge and Saint-Guillaume in October 1879. The 100-kilometre (62-mile) rail line and locomotives were converted to 4 ft 8 1⁄2 in (1,435 mm) (standard gauge) in 1881. The line was leased to the Canadian Pacific Railway in 1887 and survived into the 21st century as part of the CPR Farnham Division.
