Edaville Railroad (also branded Edaville USA and Edaville Festival of Lights) is a heritage railroad and seasonal attraction in South Carver, Massachusetts. Originally opened in 1947, it was one of the oldest heritage railroad operations in the United States. It is a 2 ft (610 mm) narrow gauge line that operates excursion trains for tourists, built by the late Ellis D. Atwood (initials E.D.A., for which Edaville is named) on his sprawling cranberry farm in Southeastern Massachusetts.
