There then came a bit of a service interruption. Philadelphia Transportation Company 2743 made it to the Blacklog Creek platform, and then because there was no loop there, the car, as programmed, was backed to the main Museum campus. While backing, the front trolley pole continually came off of the wire, when it reached the Carbarn 2 platform, the crew gave up the ghost of attempting to return to the Meadow Street platform. By this time the two Johnstown cars were right behind 2743. The passengers were discharged and the crew called for the rescue locomotive.
