The interior of the restoration shop; the car at the far left behind the yellow jacks is the former Philadelphia Rapid Transit D7, a coal trolley later converted to a vacuum car for the Broad Street Subway in the City of Philadelphia. The closed car in the centre is Philadelphia Rapid Transit 5205 with Presidential Commission Conference (“PCC”) car 2054 from the same company behind it. The orange car to the right of centre is Philadelphia Rapid Transit D37, a line maintence car. One of the museum’s tasks is to re-gauge the former Philadelphia cars from 5 foot 2 ¼ inch gauge to standard gauge for the demonstration trolley line; this is because the demonstration trolley line is also used for freight service by the Delaware Lackawanna Railroad on behalf of the Lackawanna County Rail Authority ((LCRA”). As the PCC car is single ended and lacks rear end controls, it has a lower priority on the restoration timetable, the demonstration trolley line lacks the necessary turning facilities for using such car types at its terminals. Also in the restoration shop is Scranton Transit System 524, a car that is in the final stages of restoration awaiting only the completion of re-wiring in order to re-enter service.
