Roger, your photo greatly disturbs my obviously ill-founded ancient conclusions. In my experience Yards always were vast complicated facilities. For instance the compact, yet highly complex Mott Haven Yard serving Grand Central Terminal, or the Central's Selkirk Yard south of Albany. Even B&M's East Deerfield (MA) Yard was large in its own right. Yet you now post a photo of a PRR "yard" comprising three tracks, one of which appears to wander off into oblivion. Do you realize that you may have shaken this old man's fundamental beliefs to their core? I may never recover......
Being a Santa Fe modeler, I know very little about the Pensy. But that photo looks like "house tracks" that would be on the opposite side of the main line from the freight yard itself.
Yes, there was more tracks there than just three. They were to the left of the photo. Now, bear in mind that much of the yard is no longer in use.
Now that's an interesting photo. As small as the yard may be, it obviously had sufficient business to need two steamers, one diesel, and two cabeese.
What is that thing between the EMD and the '51 Oldsmobile? Freight car trucks and a passenger car end door--but without a vestibule? Is that a maintenance of way crew accomodation car?
Yes. Exactly. Between here and two miles north, there were a lot of strange looking maintenance cars.
