A trackmobile has steel flanged wheels for movement on rails and retractable rubber tires for movement on the ground. The steel wheels remain in place while the rubber tires can be raised and lowered to fit the needs of the operator.
The Green Frog trackmobile was a vital part of the switching operation at the Hershey Chocolate Company facility in Smiths Falls. It could move three fully loaded box cars, filled with sugar, to the unloading doors then have them ready to be collected by a CPR local switching train.
The Hershey/RMEO Green Frog trackmobile was rescued from a scrap yard by RMEO legend John Weir.
