Track Updates . . . by John LaCosta
Summer and fall saw a lot of shop activity this year. After a long time out of service, the Baltimore PCC returned with a new rebuilt accelerator drum, courtesy of our own shop. It would have returned earlier in the year but had to wait until we found the root cause of the original cause of the failure. In the process of checking the sequencing of the relays after the installation of the rebuilt accelerator drum, we discovered a broken wire that had at some point touched the 600 VDC, not a good thing to happen given the wire was the low voltage ground for many of the control relays and contactors. After a careful examination of the wiring, and repair to one of the contractors, the car was run for the first time in about one year. After some minor adjustments, including the voltage regulator, the car was placed back into regular revenue service. The Baltimore PCC was not the only car to enter service during this period, the Philadelphia PCC also was placed in service as well. After an extensive set of exterior body work repairs and an excellent new coat of paint, the car was returned to service. Both in and the Baltimore PCC ran out the line, a first time that two PCCs have both been in passenger service at the same time at our museum. While not fully in service, a third PCC was running in very limited service, the Philadelphia PCC Line Car. With a new coat of paint, the car is waiting to have on last problem corrected before it is placed in regular work service. This PCC was converted by SEPTA as a line car for it subway service and has already been used to work on the BSM overhead. Speaking of the overhead, the line crew has also been busy at work doing minor repairs as well as putting up more overhead trolley wire trough over Car House 4 track. This new trough and wire allows both the Philadelphia PCC and snow plow to run into and out of the car house with having to use a "stinger" to supply 600 VDC when in the car house. In restoration work continues on our single truck electric, 417, ex-horse, with new lettering and more woodwork repairs. The track crew was not quite as active this summer due to the heat, but continued to do tie replacement and track alignment.
