Abstract: A friction shoe for a railway car truck is provided. The railway truck comprises two parallel sideframes, a suspension spring assembly supported by the sideframes, and a bolster transversely mounted between the sideframes and supported by the suspension spring assembly. Each sideframe has at least one vertical support face, and the bolster has at least one sloped support face. The friction shoe comprises a bottom base engaging and supported by a suspension control spring, a sloped face engaging the sloped wall of the bolster. The friction shoe further includes a vertical face including a pocket, with a friction liner in the pocket. The friction liner engaging the vertical column of the sideframe. The friction shoe friction liner comprised of a material providing a damping force of between 700 and 16,250 pounds and a normal force of between 2000 and 12,000 pounds.

Abstract: The invention is directed to a railway car for the transportation of semi-trucks. The railway car may have an interior defined by a support surface for the trucks, a pair of upstanding sidewalls, and a roof. End doors may be located at each end of the railway car for selectively permitting access to the interior thereof. The horizontal width at the ends of the railway car may be selected to permit the trucks to be loaded into the interior of the railway car.

Abstract: A side bearing provides contact between a truck bolster and a railway car body. The side bearing includes a cage member mounted on top of the bolster. An insert member is fit within an opening in the cage member. A top member is mounted above the insert member for vertical movement relative thereto. The insert and top members have pocket sections that together form at least one pocket there between. Resilient devices, such as elastomeric unitary pieces, are positioned in each of the pockets for supporting the top member relative to the insert member. The side bearing components we configured to provide up to 0.625 inches of vertical displacement of the top member relative to the insert member.
