Abstract
A roll control mechanism for use with a swing motion railway car truck. The control mechanism comprises a transom stop adapted to be attached to the transom of the truck. The transom stop includes a convex cylindrical surface having a tip that is adapted to engage a bolster stop attached to the bolster of the truck to limit lateral movement of the side frames of the truck. The convex cylindrical surface of the transom stop provides a low point of contact between the tip of the transom stop and the bolster stop thereby reducing the magnitude of the overturning movement created by such contact.
