We've probably mentioned this ad-infinitum but Phillip is new and it  
might also help Mark's understanding.   These are all HL control and  
not K-35 control cars.   Westinghouse HL as Pittsburgh defined it was  
generally unlike HL anywhere else.   Most Westinghouse installations  
used 600-volt contactors under the car that were closed by compressed  
air.   The Pittsburgh cars (and 3756 at PTM is sole surviving example  
of a low-floor passenger car) used electric solenoid switches similar  
to those on General Electric type-M installations.   You can see the  
contactor box under the blind side (opposite the doors) of one end of  
each of these cars.

In that beautiful Washington Park scene, it's at the near end.    On  
single-end cars, it was always on the left rear.

The double end low-floor cars all began their life with Jones  
control ... all of them ... the four converted trailers, the four  
orders of 50 each, and the dozen that came second hand from Beaver  
Valley Traction (the 4400s).   Those that survived into the 1950s all  
had either two K-35 platform controllers or two remote HL masters to  
work the solenoid switches under the car.   Of course assignments  
were set up so that, to the degree possible, each barn had identical  
car types.   Tylerdale and Charleroi had HL cars which was no problem  
because the 3700s and 3800s also had remote control schemes and the  
mechanics understood them.

I never understood why the 3750s for Sewickley were at Tunnel ... was  
it so important to keep all 3750s in one place?   Was there something  
different on them from the 5200 MU cars at Ingram?   Once Sewickley  
got PCCs they began to work out of Ingram.    The basic control  
package was the same but there might have been something different.

In general the one barn that had all sorts of odd balls was Homewood  
simply because the central parts room was a block away.
