Abstract
There is disclosed a lightweight truck sideframe for use in a railway car. The truck sideframe is of lighter weight than conventional truck sideframes because of the removal of the double wall of the truck sideframe tension member, leaving a single wall tension member. Removal of this significant mass of metal requires reinforcement of the truck sideframe in several areas including in the tension member below the spring seat, in the compression member, and at the side wall window. The resulting truck sideframe construction is of lighter weight than conventional truck sideframes and exceeds the Association of American Railroad's requirements for strength and durability.
