Abstract
A rail vehicle is disclosed to travel down a track formed from a pair of rails. The rail vehicle is propelled by a drive assembly having a longitudinal axis in line with the rails and a pair of wheel sets, each of which includes an axle with a wheel rotatably mounted on each end thereof. The drive assembly is further adapted to provide a positive angle of attack between the rotational plane of at least one wheel and the respective rail, so as to improve the stability of the vehicle. A method is also disclosed for improving the stability of a rail vehicle.
