Abstract
A wheel and track system wherein the track comprises a base and a pair of spaced apart upstanding sides is provided for guiding movement of a vehicle having four wheels over a controlled path and at least two of the wheels are mounted for rolling movement over the base and between the spaced apart upstanding sides and wherein a scuff plate is provided between the two wheels and the upstanding sides of the track so that there can be relative rotational movement between the scuff plates and the wheel and relative movement between the scuff plates and the upstanding sides of the track in the event of contact between the scuff plates and the upstanding sides of the track so as to minimize any tendency for the wheel to ride up the upstanding side and also to protect the upstanding side and the wheel from damage.
