摘要： 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.
