Not sure what neck of the woods you might be from, but another flatcar that could be done, if you so desired, would be the log flat car. They are quite unique. We had those (trains of) up in the Northwest when I was working up there in the 50's-70's and sometimes into the 80's. Most Class I railroads don't use them in these modern times. Nothing more enjoyable to see than a full train of loaded log flats with different size logs loaded upon. Seeing those huge old trees, thick bark and counting the rings at the cut were really something. Not much used anymore since most logs (what the fed's let be cut, that is) are usually hauled by trucks these days. Although I'm sure there are short line RR still hauling some today. Jim
