U.S. Gypsum ALCo/MLW DL535 Narrow Gauge Locomotive
U.S. Gypsum in Plaster City, California has a unique 3' narrow gauge railroad used to transport gypsum from its quarry.
I caught the ALCo DL535 #111 blowing its horn and crossing the street on its way to pick up empties. It's a six axle unit with a Canadian Safety Cab, typical of Montreal Locomotive Works (MLW) built units.
