Outside of a rural grain elevator there is usually a scale with a chute for offloading grain from trucks. This N-scale model represents a generic scale. The only thing you need to add is a 0.040-inch thick sheet of scribed styrene cut to a dimension of a scale 7' 6" wide by 17' 9" long. In human scale, that's 0.5625 inches by 1.33125 inches.
