ABSTRACT:
A multiple axle railway truck having side frames with pedestals, roller bearings for the axles received in the pedestal jaws with clearance in a direction fore-and-aft of the vehicle to permit relative yawing motion of the axles. A yielding pad is provided between the bearing and the base of each pedestal jaw, and a transverse plank extends between the side frames to restrain fore-and-aft motion of the side frames and is torsionally flexible thereby permitting relative angular motion of the side frames in vertical planes.
