ABSTRACT:
A combination highway and rail vehicle having front and rear sets of tires and front and rear sets of rail guide wheels. The front guide wheels are carried by a wheel suspension which swings the guide wheels into contact with the rails forwardly of the front tires and simultaneously raises the front tires, against the force of tire suspension springs, to positions above the rails. As a result, the front tires, which may be wider apart than the rails, are lifted out of the way, and the rear tires of the vehicle are required to carry a substantially greater portion of the weight of the vehicle plus its load, thereby increasing the traction between the rear tires and the rails.
