Model railroading is of course a multi-faceted hobby. So changing from one element to another is easy enough when one gets bored after working in one area too long. I needed to at least have a "diorama" section to take photo's and provide an inspiration for the finished product. The steps into the layout room are immediately to the right of the facia next to the tunnel portal. The tunnel portal itself represents tunnel 21 on the prototype. Pryor siding and Rooster rock are in the immediate vicinity. Selective Compression!!! But I've got a lot of rock castings and foliage to add before this setting is successful in providing that end.
