That truck looks like it has some kind of square tank on the back. Any idea what it was used for?
I worked at Service Tracks just like this on the Frisco during this era. I don't recognize the site but I can probably answer your question. If it truly is a tank, it would be for Lube Oil. Sand and water were easy to pipe to the track. A single viscosity oil was like tar in the winter so it was kept inside the shop or plugged into power to keep it warm.
And that guy looks like he’s walking off the job.
