The Brockville, Westport & Sault Ste. Marie Railway
This railway received its charter in 1884, and on July 1, 1888, began service between Westport and Brockville, a distance of 73 km. Lack of funds prevented the extension of this ambitious line toward its intended destination, Sault Ste. Marie, but it operated for 15 years. In 1903, unable to meet obligations incurred during construction, it was taken over by an American trust company and reorganized as the Brockville, Westport and northwestern Railway. That company was purchased in 1910 by the Canadian Northern which was itself merged in 1923 with the C.N.R. The last train to run on this line left Westport on August 30, 1952.
