ABSTRACT:
Railway maintenance vehicles are disclosed which are of the character having a frame assembly provided with drivable ground engaging tires and rail engaging flanged wheels. The frame assembly supports maintenance equipment, and the rail engaging wheels are displaceable between first and second positions relative to the frame assembly. In the first position the flanged wheels engage underlying rail members so as to support the vehicle with the ground engaging tires in suspension above ground, and in the second position the flanged wheels are elevated from the rails and the tires engage ground to support the vehicle. Heretofore, maintenance operations have been performed with the flanged wheels either in the first or second position thereof. An improvement according to the present invention provides for the flanged wheels to be displaceable to a third position engaging against the rails to provide guidance and a stabilizing force while the tires engage ground to provide the primary vehicle support and stability during maintenance operations.
