Hi,
As for the railroad , no one in my family worked at any railroad that I know of, but maybe that's a clue as to some history. My dad bought this at a auto wrecking yard, but has no history for it before that. The auto yard was using it to haul dirt and mud out of their yard. I looked to see if the yard was still around but looks like its long gone unfortunately.
I reached out to the GMC heritage center and got in contact with some one who said they needed to get into the hard copies to do research on this, I have not yet heard back but maybe that will bring something to light.
