ABSTRACT:
A multiple axle railway truck is disclosed having side frames and a plurality of axled wheelsets, with roller bearings mounted in pedestal jaws having clearance fore-and-aft of the vehicle, thereby providing freedom for relative yaw motions of the wheelsets, structure interconnecting the side frames including a transverse shear plate restraining relative fore-and-aft movement of the side frames and accommodating relative pitching movement of the side frames; flat resilient pads between the roller bearings and the base of the pedestal jaws for at least one wheelset; and a method for retrofitting existing trucks to embody the structure referred to.
