Walter- Beautiful piece of work. I have a feeling that a lot of folks are going to spend their Saturday morning sketching out a logging spur. I have several Showcase vehicles in my "paint when the basement warms up" box, and have always been impressed by the amount of detail you pack into your trucks (my favorite being the bottle truck- that one really brings back memories from childhood).
For my own "context" (which is to say, until I get a bigger basement I need to live with my current layout), were any of these locomotives used in an urban, industrial setting? The "classic" photo of a Shay is in a logging camp surrounded by lumberjacks. But I imagine they found other uses as well. Time for me to do a bit of research.
