Based on a route in Alaska that was proposed and surveyed, but never built. The route runs north from port facilities on the Pacific Ocean to the Yukon River. The principle traffic consists of copper, zinc, coal, and forest products. Entry to the layout requires negotiating 3 steps and a 50" high by 20" wide nod-under, so not wheelchair accessible. All aisles 36" or more once inside layout room. Track is 95% complete, scenery 25%
