Abstract
A truck for use on a railway vehicle has three axles, one located at each end of the truck and a third located generally centrally between the other two axles. The two outboard axles are pivotable about respective vertical axes so as to be free to move to a radial alignment when the truck is travelling on curved track. The axle located generally centrally between the other two axles is free to move laterally but is constrained to eliminate movement about a substantially vertical axis. An interconnecting member is provided so that the lateral movement of the central axle is used to guide the outboard axles to the radial alignment.
