Re: Photo: SP Flat Car(s) Transformer(s)
One of the clinics during the virtual PRR day meeting was on transformers, by Rob Bennett. One thing I learned from Rob is that there was usually a transformer for each phase. I sent the photo to Rob and he looked around a bit and found this photo:
of not just the two mentioned but THREE transformers... so this was a three-phase installation. These are GE built.

Upon closer examination I think you are correct - Re-writing:
These are two nearly-identical transformers on TWO different SP
70-ton(ish) SP Flat cars:
Photo on 4-8-1937 on SP 43595 F-50-12 ... with what look to be 70-ton
Two days later, 4-10-1937, with nearly identical load... SP 49679 ,
the lone F-70-1... nee F-50-14 with heavier trucks.
AFAIK... this is the only known (so far) photo of 49679... on what
was probably its first revenue trip.
