Abstract: An elastomeric pad is provided for use in a railway car truck that includes two sideframes and a bolster. Each sideframe has a pedestal opening at each end to receive a bearing adapter assembly. The bearing adapter assembly includes a cast steel bearing adapter that is formed to fit on top of an axle bearing assembly. An elastomeric pad, comprised of a selected hardness elastomer, is fit on top of the bearing adapter. Contact buttons extend from the top surface and bottom surface of the elastomeric pad and are received in openings in the elastomeric pad. A conductor provides an electrical connection between the contact buttons.

Abstract: A rail car truck bolster wear plate surface connects to a wear plate using two fasteners of different length. The first fastener passes through an upper opening and an upper channel into a first recess where it can be tightened against a first engaging surface. The second fastener is longer than the first fastener and passes through a lower opening and lower channel into a second recess adjacent to the first recess. The surfaces of the first and second recesses form a series of ribs in the upper end surface between the wear plate surface and the longitudinal centerline of the bolster.
