The second photo brings back some memories. When I was a kid on my grandfathers ranch he had a "railroad" that consisted of 2 or 3 hand pushed carts used to transfer the freshly cut apricots on a stack of drying trays from the cutting shed to the sulfur houses. The whole works couln't have been 75 yards long, but there were 2 sulfur houses so there was even a switch. The tracks (much smaller and closer together than the ones in the picture) were situated such that it was often necessary to drive the TT over them. ALWAYS he would put it in Muncie 1/Ford low and cross perpendicular.
Those may be Ford factory photos.
Note that in both photos that the body and box has flat paint - might be primer.
The boxcar is Detroit, Toledo and Ironton Railroad.
The DT&I ran right thru the middle of our farm, just outside of Ironton.
