The track arrangement on the layout is:

Orin is around the curve to the bottom right (southeast), and heading to the left takes us towards Glenrock (west - via the big oval "helix").

There isn't much detail here yet. Most of what I remember about Douglas is the "statue" of the cowboy on the giant Jackalope on the west side of town, the tree-lined streets, visits with my paternal grandmother when she lived there for a few years, and the truck stop (which is still there) where we always ate at the south end of town. Their chicken-fried steaks were great! That means a lot of research regarding rail service shipments in and out is needed to flesh out details here. The track arrangement is just a general one for now.
