Route 59
Castor–Bustleton to Arrott Transportation Center
Route 59 trackless trolley en route to Bells Corner
The trackless trolleys (or trolleybuses) replaced trolley cars (streetcars) on the route on in June 25, 1950.
Diesel buses temporarily replaced trackless trolleys on route 59 in June 2002, because of reconstruction of Frankford Depot (garage) and the adjacent Market-Frankford "El" viaduct and station, which required the temporary removal of the overhead trolley wires used by trackless trolleys both at the garage and along the deadhead route (under the El viaduct) connecting route 59 to the garage. However, trackless service was restored in April 2008. All of the vehicles currently in use are ADA-compliant and equipped with bicycle racks.
