A railway truck includes 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. A friction shoe includes a bottom base engaging and supported by a support spring, and a sloped wall engaging the sloped support face of the bolster. The friction shoe prevents bolster side wall wear.
