I've been thinking of how to model a shortline railroad in coal country. The locomotive power would consist of a dual-use (freight and passenger) and a local switcher. Steam, of course. The era would be the 1940s.
Coal would be from medium and small mines that might produce 1 to 4 car loads per day.
My thoughts were that the larger mine might get hoppers from a third party while the small mines might use local equipment -- like drop-bottom gondolas. The shortline would have a transfer point to regular hoppers. Obviously if the shortline was narrow gauge the latter would be true.
Did the RRs use gondolas in the way? I think so early on before hoppers made their appearance and locomotives got larger. What do you think?
