The same track from a different view:
Egads! Now I see my error. When I wrote "about a quarter mile from any railroad tracks," I should have stated "railroad," because I was thinking of the Septa/CSX/Conrail/former Reading West Trenton Line. To compound my error of imprecise language, the property I described is approximately 871.05 feet, or 0.1649621212121212 of one mile from the (former) Reading Langhorne Station. Nowhere near the .25 of one mile that I claimed.
I see that the property in your photo is at approximately 120 Monroe Ave, which was apparently his shop, and the lot I wrote about is a triangular parcel on the other side of the street. The rails in this photo point directly to that parcel. I suppose he had a track going across the street to transfer equipment from the storage lot to this building. Don't know. I'm old and forgetful and rapidly going downhill. But because I kinda like maps and wasting time and wondered if there was some forgotten lost railroad there, I searched online resources for any actual railroad on that block - as opposed to disconnected tracks. On the USGS Topoview site I viewed quad maps from 1944, 47, 66 and 93 and found nothing other than the old Reading line. (USGS may have accidentally omitted the lost railroad. They're connected with the US government, so anything is possible.) Additionally, using the Historical Aerial Viewer of Historical Aerial Photographs of Pennsylvania, I viewed aerial photos of that area from 1965, 75, 80 and 85. They're not high resolution, but I can see no railroad other than the former Reading. Coulda missed it. But please forgive my careless statement that the property I described was a "quarter mile from any railroad tracks." Now if there really was an actual railroad that connected with those stub tracks, I would love learning about it.
