I found this photo at My Link page Fallen Flags.Org, located to the right of Your computer screen.

One of the more unique, conservative, and yet very stylish color scheme ever to be painted on a diesel yard switcher locomotive, was that of the former Denver & Rio Grande Western Railroad.

This photo of a D & R,G,W EMD model SW 1200 yard switcher locomotive, was photographed at Denver Colorado way back in October of 1978.
