The Rockhill Trolley Museum is located at 430 Meadow Street, Rockhill Furnace, Pennsylvania, 19 miles (31 km) north of the Pennsylvania Turnpike and 11 miles (18 km) south of US 22, the William Penn Highway.
Founded in 1960, the museum collects and restores traction equipment (trolley, interurban and transit cars). 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.
The first car acquired by the museum in 1960 is Johnstown Traction #311. Recent acquisitions include Public Service Coordinated Transport (later New Jersey Transit), Newark, NJ Presidents' Conference Committee (PCC) Car #6 and Iowa Terminal Railroad Snow Sweeper #3.
"Railways to Yesterday Inc." is the corporate name of the organization, and for some years the museum operated under the name directly, until a desire to acknowledge and enhance its relationship with its hometown and help provide mutual promotional support resulted in its new operating name.
The museum season runs from Memorial Day weekend through October and is open additionally for special events during the holiday season, such as Polar Bear Express and Santa's Trolley.
The East Broad Top Railroad is across the street from the museum. The two organizations are not formally affiliated, and tickets are not cross-honored. However, both organizations share volunteers and labor expertise between them. The railroad has not operated public excursions since December 2011 and has operated no excursions since October 2013.
