Here are some pictures of Tom Wayburn's Rock Springs and Sweetwater County Railroad, operated by Union Pacific.  These pictures were taken in early 2008.  Steve Lancaster has been assisting Tom with his railroad.  The 3-ft by 6 ft layout is an extreme adaptation of Atlas plan N-107, and incorporates some Nn3 trackage.

The old postcard photo (fifth image below) shows Tom's prototype inspiration in Wyoming.
