Semi-Convertible Enclosed Trolley
Gomaco Trolley Company built the first closed, double-truck trolley car in the United States since the early 1900s. This authentic replica has been operating since 1986 in Lowell, Massachusetts, at the Lowell National Historical Park.
This car is an authentic reproduction of the 4100 series car manufactured by St. Louis and Laconia Car Company for the Bay State Railway in the early 1900s. Historical accuracy and attention to details were key factors in the production of this car.
