The Rockhill Trolley Museum is a museum and heritage railway in Rockhill Furnace, Pennsylvania that collects and restores trolley, interurban, and transit cars. Founded in 1960, the museum operates what has been historically referred to as the Shade Gap Electric Railway to demonstrate the operable pieces in its collection. "Shade Gap" refers to the name of a branch of the East Broad Top Railroad, from whom the museum leases it property.
