The Lowell Line is a railroad line of the MBTA Commuter Rail system, running north from Boston to Lowell, Massachusetts. Originally built as the New Hampshire Main Line of the Boston & Lowell Railroad and later operated as part of the Boston & Maine Railroad's Southern Division, the line was one of the first railroads in North America and the first major one in Massachusetts. All stations are accessible except for West Medford, Winchester Center, and Mishawum. History Boston and Lowell Railroad The Boston and Lowell Railroad started freight operations in 1835, with traffic from the Lowell mills to the Boston port. Demand for the express passenger service exceeded expectations, and in 1842 local service was added as well. The line north of Lowell was first owned by the Boston, Concord & Montreal Railroad, which was chartered in 1844. Trackage was completed as far as Wells River, Vermont, in 1853. The Boston & Maine Railroad (B&M) acquired the railroad in 1895. The line served as the route for Boston to Montreal service during the Golden Age of Rail (roughly 1880 to 1940). The Ambassador, the train from Boston's North Station to Montreal, ran through Concord, New Hampshire, along this line until 1966. This line, along with the New Englander, via Concord, White River Junction, Montpelier, ran through the northwestern section of Vermont prior to entering Quebec, Canada. The Alouette and Red Wing trains travelled to Montreal via Concord, Plymouth, Wells River and Newport in northeastern Vermont prior to entering Quebec. (The route via Wells River, St. Johnsbury and Newport was the more direct route of the two itineraries.) For this itinerary the Montreal route was marketed as an Air-line railroad. Massive cutbacks on May 18, 1958, included the end of Stoneham Branch service and the closure of Medford Hillside, Tufts College, and North Somerville stations. Cuts on June 14, 1959, ended service north of Woburn on the Woburn Loop; trains for points north were rerouted via the mainline to the east. Boston–Lowell local service was halved to seven daily round trips; Tyngsboro, Bleachery, and South Wilmington stations were closed. B&M passenger service to Boston on the line was shortened from Concord, New Hampshire to Lowell in 1967. MBTA era In 1973, the MBTA bought the Lowell line, along with the Haverhill and all other local Greater Boston passenger lines. Along with the sale, the B&M contracted to run the passenger
