Abstract: A cushioning apparatus for a railway car employs a shortened yoke with a reduced-width tail for placement between stops in a conventional railway car sill. A first stack of rigid plates with elastomeric pads is provided between the straps of the modified yoke behind the coupler follower, and a second stack of plates and elastomeric pads is positioned in the sill behind the modified yoke to absorb buff loads on the coupler. In embodiments, the entire assembly may be placed in a sill having forward stops, intermediate stops, and rear stops, adapted to house a hydraulic cushioning unit.

Abstract: A cushioning device includes a first housing with a first wall, a first extremity, a first open end and a first hollow interior. A second housing includes a second wall, a second extremity, a second open end and a second hollow interior, the second hollow interior sized to receive the first wall therewithin. A spring is disposed within each of the first and second hollow interiors between the first extremity and the second extremity. The first and the second housings are designed for a reciprocal linear movement relative to each other between a first position where the first open end being disposed at a distance from the second extremity and a second position where the first open end being disposed in a direct contact with the second extremity. The cushioning device may be installed within a sill of a railcar to cushion buff or draft forces from a coupler.

Abstract: A yoke for a railway car is provided with a coupler support protruding from a top wall of the yoke into an interior space in the yoke to contact the coupler shank when the coupler head is deflected downward to prevent the coupler from drooping after prolonged use.

Abstract: A hybrid cushioning apparatus for a railway car apparatus employs a standard yoke and a conventional draft gear forward of the tail of the yoke and a stack of elastomeric units behind the tail engaging the draft gear with a force transfer member.

Abstract: A cushioning apparatus for a railway car employs a shortened yoke having a draft gear housing integral with the yoke. A stack elastomeric pads is provided in the housing, and a second stack of elastomeric pads and corresponding rigid metal plates, is positioned in the sill behind the modified yoke to absorb buff loads on the coupler. In embodiments, the entire assembly may be placed in a sill having forward stops, intermediate stops, and rear stops.

Abstract: A selective cushioning apparatus for a railway car comprises an E-Type yoke having a stack of elastomeric units assembled in the interior space in the yoke absorbing draft and buff loads applied to a coupler of a railway car. The yoke is provided with butt support protruding from the top wall of the yoke to prevent the coupler from drooping after prolonged use.

Abstract: A selective cushioning apparatus for a railway car absorbs draft and buff loads applied to a coupler of a railway car during train assembly and normal operation. The apparatus according to the invention provides better cushioning than a conventional draft gear without the excessive travel and maintenance issues of a hydraulic cushioning unit. In embodiments, the selective cushioning unit is adapted to fit into an AAR standard pocket for a hydraulic cushioning unit.

Abstract: A truck mounted braking system is provided with a mechanical pivot adjustment on the bake lever connected to the brake cylinder push rod to permit the braking force applied to the wheels to vary depending on the lading condition of the car, without involving additional pneumatic elements such as a pneumatic empty load device. The brake cylinder may be provided with a channel which permits the push rod to achieve different positions based on different positions of the brake cylinder push rod.

Abstract: An improved selective travel cushioning device for a railway car is responsive to both draft and buff loads on the coupler, fitting into a standard cushioning unit pocket with little or no reconfiguration of the sill required, while limiting wear on elastic members in the cushioning unit and exhibiting high energy absorption.

Abstract: A system and method for manufacturing and/or reconditioning side frames and bolsters for railway cars includes at least one robot adapted to access positions along the length of the part. A map of the part dimensions, which may be obtained by a probe or scanner on the robot(s), allows a processor to determine where welding and machining are required to meet certain dimensional tolerances, leveraging novel reference surfaces on the part which cannot be leveraged using conventional gauges. The robot(s) may locate and mount welding and material removal tools to carry out the welding and material removal operations determined by the processor.
