A high-rail assembly for use with a high-rail vehicle to prevent derailment upon the negotiation of a tight railway curve. The high-rail assembly is comprised of a friction hub, which is attached to a shaft supported by a pivotal bracket assembly. The high-rail assembly further comprises a rail wheel assembly that is supported by a second shaft. The friction hub is adapted to engage the drive wheels of the truck and in turn causes the rotation of the of the rail wheel assembly, which ultimately drives the high-rail truck. Movement of the friction hub and rail drive wheel is accomplished by use of a hydraulic cylinder, which pivots a bracket assembly. The present arrangement allows the wheelbase between the rail drive wheels to be minimized, permitting the high-rail truck to negotiate tight radius curves without derailing.
