Preserving Railroad History Since 1986
The N.C.N.G. Historical Model Railroad is a 501(c)(3) nonprofit, all-volunteer organization dedicated to preserving the memory of the Nevada County Narrow Gauge Railroad.
Keeping History Alive
Our mission is to educate the public about the historic Nevada County Narrow Gauge Railroad through our meticulously crafted On3 scale model railroad. The original N.C.N.G. railroad operated from 1875 to 1942, serving the gold mining communities of Nevada City, Grass Valley, and connecting them to the transcontinental railroad at Colfax.
Through accurate modeling of the locomotives, rolling stock, structures, and scenery, we bring this important piece of California history to life for new generations.
