Nevada County
Narrow Gauge
Historical Model Railroad
An On3 scale model preserving the railroad that connected Nevada City, Grass Valley, Chicago Park, and Colfax from 1875 to 1942.
A Working Model of the N.C.N.G.
Built by volunteers since 1986, the layout interprets the Nevada County Narrow Gauge Railroad in operating On3 scale. It follows the line through Nevada City, Grass Valley, Chicago Park, and Colfax, with scenes such as Town Talk and the Bear River Bridge.
