Abstract
A slackless drawbar arrangement for unit train service and the like including a drawbar having enlarged butt end portions each provided with essentially spherical buff and draft load bearing surfaces on the rear and forward surfaces thereof. The enlarged butt end portions are supported by a front draft block and a rear buff block within a center sill. The front draft block is supported against a curved surface of a wear block which is, in turn, supported by keys welded to the sill. The rear buff block is supported against a gravity-activated wedge which is, in turn, supported by rear draft lugs welded to the center sill. A bottom plate retains the various blocks inside the cavity of the center sill.
