Lowell is the fourth largest city in the state of Massachusets. The city is known as the cradle of the industrial revolution in the United States. Many of the city's historic sites have been preserved by the National Park Service.

A heritage tramway system mainly connects the Lowell National Park Service Visitor’s Center and adjacent parking lots, with Boott Cotton Mills Museum, Tsongas Industrial History Center and Morgan Cultural Center. The two additional branches to the Middlesex Community College and the Suffolk Mills are operated on demand.

A comprehensive study on the tram system’s citywide expansion was concluded in 2011, which recommended an 11,1 km. line with 20 stations.
