An improved swing-motion truck (10) in which the transom has been replaced by a pair of transverse radius or tie rods (40, 42) for coupling the two rocker seats (22) of the two side frames (12) of the truck. The ends of the rods (40, 42) are directly cou- pled to anchor brackets (46, 48) formed as part of the side-frame rocker seats (22) via an elastomeric connection (60, 62). The su- spension springs (30) of the railway freight car truck are seated directly upon the upper flat surface of the two rocker seats (22) of the side frames (12) of the truck (10) so that lighter-weight freight cars may be accommodated, without a friction-dependent coupling between the rocker seats (22) and rods (40, 42) interconnecting the rocker seats (22), and where an overall lower height truck results to provide a low-deck car. The cooperating limit stops (50) for lateral motion of the truck are mounted directly on the rocker seats (22) themselves.
