The invention relates to a railway car truck incorporating a novel interconnection between the side frame (12) and bearing adapter (18) characterized by a low lateral spring constant relative to the longitudinal spring constant. The interconnection provides a proportional restoring force with minimal internal friction and hysteresis. In embodiments, the interconnection comprises compressed elastomeric members (24) positioned between the thrust lug (22) of the side frame and the bearing adapter (18) in the longitudinal direction and a low friction interface between the roof of the pedestal jaw and the top of the bearing adapter.
