The Rocky Mountain Railroad Club has opened their archives of the works of Otto Perry and Irv August noted rail photographers to give us a glimpse in and around the town of Gunnison, Colorado in the 1940s and 1950s. Gunnison was a division point on the Denver & Rio Grande Western's original narrow gauge mainline to Salt Lake City. Marshall Pass is located to the east of Gunnison, Crested Butte and Baldwin branches to the north, and Black Canyon and Cerro Summit are to the west. This show highlights DRGW's biggest to smallest narrow gauge locomotives from the Class K-36 and K-37 to the C-16s . . Mudhens and outside frame 2-8-0 C-21s.
