Abstract: An articulated railway truck assembly is provided with a pair of side frames, a transverse center support structure and a pair of wheelset swiveling assemblies. An inward portion of each of the wheelset swiveling assemblies is supported by either the side frames or the center support structure, permitting both substantially universal pivotal movement of the respective wheelset swiveling assembly and lateral movement of the respective inward portion thereof relative to the center support structure. The wheelset swiveling assemblies are resiliently interconnected by a pivot point type connection near the center of the truck for pivoting each wheelset swiveling assembly against the other within the truck framework.

Abstract: An articulated railway truck assembly is provided with two wheelset assemblies, each of which is attached for pivotal movement about a pivot near the center of the truck frame assembly and each of which extends beneath the respective adjacent ends of the side frames, with resilient support connectors between and joined to the adjacent portions of each wheel frame and side frame for permitting pivotal movement of each wheelset assembly about the respective pivot by resilient deformation of the connectors, whereby the connectors provide restoring forces for returning the wheelsets to the "square" position.
