One of the unusual jobs possible on the depressed trackis the changing of engine truck wheels without the use ofjacks. By blocking under the spring rigging and tying upthe engine truck it is possible to move the truck wheels overthe depression, take off the pilot and front pedestals, rollingthe wheels out and applying a new pair. There is no par-ticular labor-saving by this method over the of a droppit but it may on occasion be extremely valuable in round-houses having no drop pit facilities. With a proper understanding of how to do the job anengine truck spring can be changed using the depressed track. oil is used, directed on the locomotive by a jtt of air. Withone operator working on each side no time is lost. Themethod is effective in keeping the locomotives clean and isrelatively ine.\]5ensive, since the hot water is obtained throughthe boiler washing outfit from locomotives blown off on ac-count of necessary boiler work. Arrangement is made forample circulation of the water in cold weather and as a result
