Abstract of the Disclosure A self steering truck has the two wheel and axle sets mounted in the truck frame by bearing adapters that permit the small horizontal excursions necessary for steering and also spring the wheel sets for vertical springing. Each pair of bearing ?adapters is connected together by a U-shaped steering yoke assembly that extend around the outside of the truck frame to leave its interior clear for truck fittings, such as a bolster and brake set. The arms of the two steering yokes extend toward one another and are connected by connecting means that permit pivoting of the arm ends relative to one another and also longitudinal movements. The wheels are thus held against bunting oscillations while running on straight track and the axles are permitted to assume radial positions relative to the track under the action of the curved wheel running surfaces.
