A mount for use in the suspension system of a railway truck that limits the relative lateral movement between a side frame member and a bearing adapter. In one embodiment, the mount includes a rigid material layer having at least four sections laterally angled between a horizontal axis and vertical axis. A first and second elastic material layer are respectively positioned between the side frame member and rigid material layer, and between the rigid material layers and bearing adapter. The first elastic material layer has at least four sections abutting and conforming to the at least four sections of the rigid material layer. In addition, the second elastic material layer has at least four sections abutting and conforming to the at least four sections of the rigid material layer. The angled sections cooperate to increase the lateral spring rate of the mount, thereby improving the ride characteristics and high speed stability of the railway truck.
