The invention provides a novel auxiliary truck for supporting a rail car wheel- axle set above and out of contact with parallel rail tracks, to enable a rail car with inoperative wheels to be shunted along the tracks to a repair location. The auxiliary truck has two parallel truck wheel axle assemblies, upon which are mounted two rail car wheel support assemblies. Each axle assembly includes two truck wheels centrally mounted on stub axles, and each stub axle is releasably secured into a transverse tubular brace. The support assemblies are built up of a pair of parallel elongate plates, with one truck wheel from each of the two axle assemblies disposed between. Each plate includes a stub axle cradle for releasably journalling the stub axles. Two shoulder pins releasably connect a central portion of each parallel plate pair together spaced apart a selected distance. The stub axle cradle preferably forms a semicylindrical recess disposed at lower front and rear corners of each plate with an open mouth inclined at an acute angle relative to horizontal. Although the carrying capacity of the assembled truck is over 75 tons, the individual components of the truck all weight under 90 pounds and can be easily carried by members of the train crew to the site of the inoperative wheel. No tools are required since the components are secured with pins and snap rings that are quickly removed and replaced by hand. The simple design of components lowers cost to the extent that it is practical to include such a truck as standard equipment for each train.
