The prototypes for coal mine tipples like the N Scale Walthers Cornerstone New River Mining Company kit are typical of 1950s corrugated structures, many of which are still served today. Based on a trackside coal tipple for loading hoppers or gondolas, this easy-to-build kit features realistic corrugated metal construction, steel supports and separate ladders and stairways. New River is set up to load hoppers on three tracks, and if you're modeling a mine that loads coal trucks for short hauls you can choose to replace a track with a road. The New River Mining Co. also includes a conveyor with supports that can be run underground into the mine or distant mine head.
