It is modeled after the Helena, Montana area. DC powered with three levels, horseshoe grades at 2%, 4-5 engines per train because of the grades and over 40 car trains. Some trains use DPU's on the back and some are mid-train. A little interesting fact is that most of the scenery materials such as the rocks, dirt, ballast etc was collected from Montana.
