Rail vehicle drive arrangement

摘要

Rail vehicle drive arrangement, wherein each wheel 12 is driven independently. Sensors 18 are provided to determine the alignment of the track 20 in front of the wheels 12. The speed of the wheels 12 is controlled relative to each other in response to the determined alignment of the track such that each wheel rotates at a required respective speed relative to the curvature of the track 20 for the vehicle to move with no wheel slippage.
