and the bolster has at least one sloped support face. The friction shoe comprises a bottom base engaging and supported by a pair of support springs, and a sloped wall engaging the sloped support face of the bolster. The bottom base includes a cylindrical spring lug that has a center opening that extends through the spring lug. The bottom surface of the spring lug is flat and smooth and is designed to engage with and provides the ability to use an additional concentrically nested support spring. The additional spring increases the force between the vertical support face of the wedge and the vertical wear plate of the side frame.
