St. Lawrence and Atlantic Railroad
transport company
The St. Lawrence and Atlantic Railroad (reporting mark SLR), known as St-Laurent et Atlantique Quebec (reporting mark SLQ) in Canada, is a short-line railway operating between Portland, Maine, on the Atlantic Ocean, and Montreal, Quebec, on the St. Lawrence River. It crosses the Canada–US border at Norton, Vermont, and Stanhope, Quebec, and is owned by short-line operator Genesee & Wyoming.
The line was built by the Atlantic and St. Lawrence Railroad in the U.S. and the St. Lawrence and Atlantic Railway in Canada, meeting at Island Pond, Vermont, south of the international border. Major communities served include Portland and Lewiston in Maine; Berlin, New Hampshire; Island Pond, Vermont; and Sherbrooke and Montreal in Quebec.
History
The line was proposed as a connection between Portland and Sherbrooke, Canada East, in 1844 by Portland entrepreneur John A. Poor. Portland was desperate to connect its ice-free port with Montreal, and Maine was at risk of being eclipsed by a similar proposal running from nearby Boston, Massachusetts.
