Abstract: A friction wedge assembly for use in a suspension system of railroad car trucks. The friction wedge assembly comprises a cast metal wedge having a bottom face, a vertical face that is substantially perpendicular to the bottom face and a sloped face for contacting a mating surface on a bolster of such railroad car truck. There is a metal backing plate that has a first side removably engageable with the vertical face of the cast metal wedge, a means for securing the metal backing plate to the cast metal wedge and a composition liner disposed on a second side of the metal backing plate for engaging such metal wear liner on such side frame of such railroad car truck.

Abstract: The present invention provides a friction management brake shoe adapted to engage the tread and the flange of a wheel of a railway vehicle via which the railway vehicle is guidably supported on a railed track. The friction management brake shoe comprises a brake lining affixed which has a braking surface engageable with the wheel tread of a wheel of a railway vehicle. The brake lining includes a first friction composition material formed with at least one of a solid high positive friction modifier and a solid very high positive friction modifier which establish a required friction level between the wheel tread and the railed track.
