ABSTRACT:
A radial axle railway truck has separate depressed center beam-type side frames mounted at their ends on journal bearing assemblies by means of elastomeric pad devices between downwardly facing surfaces on the side frames and upwardly facing surfaces on the bearing assemblies, the pad devices near the ends of the side frames being at a level higher than the axle centers and laterally inboard of the side frames and those remote from the ends of the side frames being at a level lower than the axle centers and laterally outboard of the side frames, thereby conforming with sloping end portions of the side frames and stabilizing the side frames against tipping transversely. The main frame of the truck has longitudinally extending side members and the side frames mount vertically acting resilient means for supporting the main frame on the side frames. Each side frame is of box section formed with an elongated upwardly open pocket in its depressed central portion receiving vertically resilient means supporting the ends of the elongated side members of a main frame at a low level while maintaining an adequate cross section in the depressed central portions of the respective side frames.
