I was planning to make a small diorama, which features a peanut mill as the central feature. The main building will be the Pikestuff Milton corporation, but I am trying to decide how I can build the structure that loads covered hopper cars. I was going to use the Walther's surge bin from their modern grain kits (here), but I was not sure if the bottom structure was tall enough to run a track and load a car under. Does anyone have suggestions for what I could use to represent the car loading portion of the mill?
