The D&RGW Fourth Division was part of the narrow gauge empire in southern Colorado and northern New Mexico. This 1950s-1960s-era, 13’ x 13’ two-level layout depicts the standard gauge eastward from Alamosa, and the narrow gauge westward to Chama (NM) and beyond. The upper level is a loop-to-loop narrow gauge line passing through Chama, Cumbres Pass, Tanglefoot Curve and a freelanced Toltec Mining District, with occasional helper service up the hill to Cumbres. All benchwork and trackwork is complete; the scenery on the upper level is 80% complete, and many of the structures and bridges are scratchbuilt.
The upper level is connected to the lower by a 4-1/2 turn helix, with the narrow gauge terminating at the dual gauge Alamosa yard and standard gauge branch from Pueblo. Scenery on the lower level is 50% complete. Most locomotives, including several Blackstone Mudhens, are equipped with Tsunami sound (DCC).
