ABSTRACT:
A vehicle adapted for operating on roadway and railway includes a frame, a plurality of roadwheels and at least two pairs of retractable railwheels. The rear railwheels are mounted to the frame by means of an adjustable suspension arrangement which is adapted for moving the railwheels between a roadway configuration, in which the railwheels are retracted and support and drive for the vechicle is provided by the roadwheels, and a railway configuration in which the railwheels are extended and adapted to locate the vehicle on a railway. In the railway configuration, at least one pair of railwheels are adapted to be driven. In one embodiment, railwheels are provided adjacent rear roadwheels of the vehicle and are adapted to be driven when in the railway configuration. The suspension for the rear railways may be adjusted such that the proportion of the weight of the vehicle supported by the railwheels is varied. In a further embodiment, a front pair of railwheels are provided adjacent the front roadwheels and are provided with an independent drive.
