Chronology
1938
An Alco HH900 diesel-electric switching locomotive tested on D&RGW in late January and possibly early February 1938. The locomotive was given a temporary D&RGW number, #100. It later became Alco demonstrator #101 and was sold to Rock Island.

D&RGW's six Challengers were diverted from a UP order by the War Production Board in June 1943. Rio Grande leased them from the WPB until 1947. In the four years between 1943 and 1947, D&RGW regularly been stored these six locomotives because their shop forces found them so difficult to work on. The WPB then sold them to Clinchfield where they continued to operate until 1963, a span of 16 years, far longer than they were on D&RGW.

During 1946, the yellow stripes color of the diesel cab unit paint scheme was changed from the previous ochre yellow (Dulux Gold) to the newer yellow color (Duco Imitation Gold). This same change in yellow color took place on the end stripes of the switcher fleet, with the earlier color having been used on the GE 44-ton units, the Baldwin VO-660s, and the Alco S-2s. The later Fairbanks-Morse switchers were delivered with the new yellow color.
D&RGW sold Class C-28 2-8-0 683 to the San Luis Valley Southern Railroad in May 1947. The locomotive was sold to the Colorado Railroad Museum in 1962 and is today preserved at the museum's grounds in Golden, Colorado, as the only example of preserved Rio Grande standard gauge steam locomotives.

During May 1954, due to a downturn in traffic levels, D&RGW reportedly had only three steam locomotives in operation: two 2-8-0s switching in Salt Lake City, Utah, and a single 2-8-0 in local service in Alamosa, Colorado. In June 1954, the last 12 steam locomotives were transferred from the Salt Lake Division (Ogden to Helper, Utah), with number 3610, a 2-8-8-2, being the last steam locomotive in operation on the Salt Lake Division, as it moved under its own power to be used in helper service at Minturn, on the west slope of Tennessee Pass. At year's end, there were a total of 36 steam locomotives reported in operation, most during the August to December time period, and most in switching and helper service on the Pueblo Division (east of Bond, Colorado, on the Moffat Line, and Salida, Colorado, on the Royal Gorge Line).

By year end, all remaining standard gauge steam locomotives had been retired and scrapped. No standard gauge steam locomotives were preserved by the railroad.

D&RGW's SD7s, SD9s, and GP9s were first stored during the traffic slowdown of 1982. Most remained in storage until retirement, except small numbers of GP9s that were reactivated in 1983 for special, non-revenue trains, including GP9s 5924, 5944, and 5954, which were assigned to work train service. Many GP9s, SD7s and SD9s were reactivated during 1989, following the SP merger, for local and transfer work in the Denver and Pueblo areas.
