Abstract of the Disclosure A low rate soft primary suspension system for a railway truck includes a pair of longitudinally disposed assemblies on opposite sides of a journal bearing for carrying a wheel-axle unit. Each of said assemblies includes a plurality of laminated rubber strips separated by relatively thin metal strips oriented parallel to the vertical axis of the journal bearing. The layers of the laminated assembly form angles opening towards or away from the journal bearing somewhat in the shape of chevrons. The assemblies provide relatively high spring rates for lateral and longitudinal loads and low spring rates for vertical loads.
