Abstract
A track traveling vehicle having rubber tires for engaging a public road to permit the vehicle to travel thereon, and also having metal wheels capable of engaging rails associated with a track for permitting the vehicle to travel therealong. The metal wheels are supported on the chassis of the vehicle for vertical movement between a raised position wherein the rubber tires engage the road, and a lowered position wherein the metal wheels engage the rails and the rubber tires are maintained in an upwardly suspended non-engaged position. Hydraulic pumps are driven by the rubber tires when they are in the raised suspended position, and the hydraulic pumps supply hydraulic fluid to hydraulic motors to effect driving thereof. The hydraulic motors are in turn drivingly coupled to either the front or rear metal wheels to effect driving thereof when the metal wheels are engaged on the rails so that the vehicle can travel therealong.
