The London and Port Stanley Railway (L&PS or L&PSR) is a historic Canadian railway located in southwestern Ontario. It linked the city of London with Port Stanley on the northern shore of Lake Erie, a distance of approximately 25 miles (40 km).
The L&PS was one of the first railways to be built in Ontario, with construction starting in 1856. It provided connections between London, St. Thomas, Ontario and Port Stanley, Ontario. It was built primarily to facilitate trade with the United States, particularly of wood and coal. As a result of its rail connection, a substantial investment was made in the port facilities of Port Stanley, which in turn attracted American and Canadian shipping. Until 1932, coal from Conneaut, Ohio, was transported via railroad car ferries to Port Stanley.
The railroad also proved popular with local residents, particularly in the summer when many commuters utilized the system to travel to Port Stanley’s beach and resort facilities. However, the railway's service was not always impeccable, as it also earned the nicknames Late & Poor Service, Lost & Presumed Sunk, and Lean, Push & Shove.
Originally, the railway operated steam locomotives, with the first passenger train arriving in 1856. In 1914 the line was leased by the City of London, which proceeded to electrify it. The City bought the line outright in 1950, 36 years into its 99-year lease. During the 1950s passenger traffic suffered from automobile competition, and passenger operations were suspended in February 1957. Canadian National purchased the line in 1965.
The London & Port Stanley Railway was inducted into the North America Railway Hall of Fame (NARHF) in 2008 in the "Local" category for "Communities, Business, Governments and Groups" for those who have made significant contributions or achievements relating to the railway industry. The L&PS made good use of the Canada Southern Railway Station in St. Thomas (home to NARHF,) helping to make it one of the busiest station in the country in the early 20th century.
