This begs some questions doesn't it but I recognize since much of
the info about back up controllers is new to all of us that answers to
these questions will be elusive at best:
Just guessing that the 'front' deadman (as same apparently didn't exist in the rear) was tied down when using rear controls on 38s.
When did deadman controls appear on trolleys?
I was under the impression that one set of handles were available for each trolley and were moved from end to end on DE equipment. Special configurations on these handles prevented someone from using a stick or pole to operate from the 'rear' end. This same method could be used for simple rear controllers and apparently was on the 3750s and possibly the Brills as well.
Why the difference with the 38s?
Were problems experienced with the 3750s that prompted this change?
In reference to braking I have heard the term 'self-lapping' which is apparently easier to use isn't it; this prevents the lurch on the final stop. What does the term 'self-lapping' actually mean?
PRC operators told me that on 10 and 11 series PCCs they were to release the brake and reapply just before the final stop to prevent lurching. Didn't they have self-lapping brakes? This was not true of subsequent orders of PCCs; 12s had spring applied brakes of course but 14s and 15s had wheel brake shoes didn't they. The 16s were delivered with drums and it would seem that the smaller surface area available for braking and high rpm relative to wheel brake shoes would over ride concerns of lurching.

Pardon the observation but it was a sailor so this sounds like a ' sea story' doesn't it. You mentioned that there was a high degree of professionalism among staff and management; while there was animosity with the unions the operators were highly professional as well weren't they. I was always very much impressed with this. This story goes against that grain of professionalism. Even motormen are human so it is very possible. I personally know someone who claims to have worked the 44/48 owl with PCCs while the motorman was keeping his girlfriend warm but I am a skeptic of that as well. It would seem highly logical to have supervisors at South Hills for 24-hours; certainly there were roving supervisors all night.

Did anyone have experience at the Riverview wye? Maybe a Donora local would assist here.
