David - many of them were re-constituted boxcars of one kind or another, and instead of scrapping them or setting them afire to warm the railroadmen of a cold winter night, they made use of them instead. Makes sense when your railroad is down on its luck and dyin’ away.
If you look at the Mo-Pac you’ll see that some of their transfer cabeese are nothing more than a chicken coop on a flat car…leastways, they look like that.
The Hull-Oakes Lumber business in Dawson OR used to have its products collected from the class 1 at Corvallis, and because there was no Y or other way of effecting a turnaround, they used to back the lumber train all the way from Corvallis yard to the lumber yard, with a nice old Mo-Pac transfer caboose heading up…
It’s well-worth getting onto Youtube and looking at the H-O set-up, one of the very few STEAM-DRIVEN lumber yards left in the entire US of A.
