Abstract
Abstract Brake rigging for a railway freight car having a center sill structure with an open bottom and receiving a portion of the brake rigging. The truck live lever and the truck dead lever extend in a vertical direction and have upper end portions received within the center sill structure. A truck lever rod wholly within the center sill structure connects the upper ends of the truck levers and extends over the truck bolster and the body center plate. An actuating pull rod is connected to an intermediate portion of the truck live lever for actuating the truck brakes.
