The Wiscasset, Waterville and Farmington Railway is a 2 ft (610 mm) narrow gauge railway. The line was operated as a for-profit company from 1895 until 1933 between the Maine towns of Wiscasset, Albion, and Winslow, but was abandoned in 1936. Today, about two miles (3.2 km) of the track in the town of Alna has been rebuilt and is operated by the non-profit Wiscasset, Waterville and Farmington Railway Museum as a heritage railroad offering passenger excursion trains and hauling occasional cargo.
