Chicago, Burlington and Quincy Railroad steam locomotive #5633 was built in the railroad's shops at West Burlington, Iowa, in September 1940 as one of the last class of steam locomotives on the Burlington. It was part of an order for twenty-eight identical 317-ton units assigned Class 0-5A and designed for fast freight and heavy passenger service. Baldwin Locomotive Works supplied the boiler, General Steel Cashing of Chicago supplied the one-piece engine beds, and the locomotive had roller bearings and Baker Valve Gear. It saw service systemwide on the Chicago, Burlington and Quincy, although evidence indicates that #5633 was not operated on the Colorado and Southern through Douglas. The locomotive remained in service until 1956 and was then stored at Lincoln, Nebraska. In April 1962, it was moved dead-in-train from Galesburg, Illinois, to Orin and then via the Chicago and North Western Railroad to Douglas. State Senator Charles G. Irwin and William Lindmier, Jr., were key to securing its donation to the people of the State of Wyoming by the Chicago, Burlington and Quincy Railroad Company, and title was transferred to the City of Douglas in 1993. Five of these locomotives are preserved in parks and museums, including #5633 in Douglas, Wyoming.
