Abstract
A railway guide wheel apparatus attaches to a frame of a road vehicle to allow the road vehicle to travel along rails. The apparatus has a side shift capability where railway wheels of the apparatus may be lowered to engage rails even when the vehicle is offset sideways from the rails. An automatic centering arrangement will center the vehicle relative to the rails after the railway wheels have engaged the rails. Spring cells are used as a suspension to absorb vibration from the railway wheels contacting the rails and to maintain the railway wheels in contact with the rails.
