The concrete railside loading dock and the side tank pad were built from laminated 0.080 inch styrene sheets. Mr. Moore shows the loading dock with four steps on either end; however, I thought that since this meant that each riser was about a foot tall, they were too steep for actual steps and looked a little odd. It turns out that 0.80 inch styrene is approximately equal to 7 inches in HO-scale, I re-sized the stairs so that each piece of 0.080 laminate corresponds to one step. It turns out this means there are 6, 0.080 steps, with 12 inch scale treads, and the top step is made from 0.060 inch styrene to get the whole unit to come level with the door sill. This also means that the total length of the staircases are longer than in Mr. Moore's model, but looks a little more realistic when a figure is placed beside it.
