Abstract: A railway truck pedestal has a pedestal tie bar irremovably secured to one of the pedestal legs but arranged for easy movement between open and closed positions. The tie bar is of generally I-shape in plan and it is slidably mounted in channel-shaped saddles secured by their flanges to the bottom of the pedestal feet to provide generally aligned openings extending lengthwise of the pedestal.

Abstract: For supporting equipment such as third rail collection gear, which must be maintained at constant height above the rails, on inside bearing trucks in which the truck frame is spring-supported from journal boxes vertically movable relative to box section truck frame side members, equipment support beams extend longitudinally of the truck within the respective frame side members and are pivotally supported at their ends from the respective journal boxes.

Abstract: A radial axle railway truck of the rigid frame type has an improved primary suspension for resiliently supporting the truck frame from the axles while permitting arcuate movements of the ends of the axles required to allow the axles to assume radial positions on curved track and an improved disc brake system arranged to minimize interference with wheel-induced steering movements of the axles. The primary suspension comprises journal bearing structures with fore and aft wings, a yoke supported on the wings by flat elastomeric pads yieldable horizontally to accommodate steering movements of the axles and chevron-shaped elastomeric springs carried on the yokes fore and aft of the respective journal boxes and acting in parallel with metal coil springs carried by the yokes.

Abstract: A radial axle railway truck is provided with a disc brake system compatible with the radial axles comprising a single disc at the center of each axle adapted to be frictionally engaged by opposing shoes of a disc brake mechanism, the disc brake mechanism associated with each axle being supported by a yoke anti-rotatably mounted solely on truck framing supporting adaptors mounted on the axle bearings to take braking torque while accommodating free pivoting movement of the brake mechanism in the horizontal plane in accordance with movements of the axles from their tangent track positions to their curved track radial positions, such that no forces are applied by the disc brake mechanisms to the respective axles in opposition to the steering forces acting on the respective axles.
