ABSTRACT:
A railway truck has frames on each side divided into separate components or lever arms extending from the axles. Opposed arms are secured together by a pair of parallel torque tubes. A bolster rides on the tubes and maintains the tubes in parallel and provides frictional damping. The torsion tubes each carry a pair of torsion bars secured at the inner end to the torque tube and to the outer end to the bolster. Unequal loads on opposite wheels are carried equally by the torsion tubes.
