[PRCo] more bits which are gone?

[Derrick J Brashear]

all of my maps are not handy at the moment but I had occasion to go to
52nd and Butler yesterday (a friend rented a Ryder truck from a garage
there) and passed were I could swear there was a substation, only now
there was a flat lot with some red brick residue. Was there a substation
at 57th and Butler, northeast corner? Because, if so, hope someone got
some pictures. (I may be misremembering and it may have been Duquesne
Light and not Pittsburgh Railways, but the fog won't lift in my mind)
