Abstract
A load-carrying railway truck having a longitudinal axis in its direction of travel and including at least one load-bearing member for supporting a load; a pair of live wheelsets supporting the load-bearing member, each wheelset being so mounted in the truck and having such a profile that it is substantially self-steering; means interconnecting the wheelsets to transmit yawing and lateral movements of either wheelset in the opposite sense to the other wheelset; and elastic elements suspending the load to the wheelsets, at least some of the elastic elements having a lateral stiffness in a direction transverse to the longitudinal axis of the truck which is lower than the stiffness provided by them in a direction parallel to the longitudinal axis.
