The system has two opposite independently sprung and steerable flangeless wheels 13, 14 on the same axle line, each having an associated flanged wheel 15, 16 controllably liftable at points &c to enable the vehicle to be used on railway tracks without gaps in the rails. The rail vehicle is able to steer using reaction forces of the flangeless wheel/rail contact patches only. Loads on the wheels 13,14,15,16 can be varied by means of respective hydraulic rams, using control circuits, to steer the vehicle. Hydraulic rams are used to provide the lifting of the flanged wheels. |
