Abstract: A friction shoe for a railway car truck is provided. The railway truck comprises two parallel side frames, a suspension spring assembly supported by the side frames, and a bolster transversely mounted between the side frames and supported by the suspension spring assembly. Each side frame has at least one vertical support face, and the bolster has at least one sloped support face. The friction shoe comprises a sloped wall engaging the sloped support face of the bolster, a vertical wall engaging the side frame vertical support face, and a bottom base engaging and supported by a suspension control spring group which comprises three concentrically nested coil springs which provide a normal force on the column wear plate of between 3000 and 5000 pounds in the static empty railway car truck condition and between 7,500 and 12,000 pounds force under the static loaded railway car truck condition.
