 Motive power for each train consisted of an integral head-end unit driven by a Chevrolet 265 cu in (4.3 L) displacement V8 gasoline engine, mated to a Jeep transfer case powering drive-shafts to both the front and rear wheel trucks.Two 1954 Oldsmobile 88 2-dr coupes furnished the windscreen, doors and instrument console for each of the two locomotives.The attraction operated until September 30, 1958 when construction began on the Matterhorn and Submarine Voyage.
