  • Patent number: 9180893
    Abstract: A railway tank car including a protective structure for the top of its cargo tank and surrounding both a valve group mounting nozzle and a pressure relief safety valve nozzle, to protect the associated valves against damage resulting from the car being overturned, particularly while the railcar is moving along a railway. The protective structure includes protective housings including upstanding walls of metal plate construction surrounding the nozzles yet not attached directly to the nozzles, so that the protective housings afford convenient access to the valves associated with the nozzles.

  • Publication number: 20150284012
    Abstract: A fully protective railroad freight car for carrying motor vehicles in a selected one of a bi-level or a tri-level configuration, with the lowest level including a depressed longitudinally central portion between body bolsters of the underbody, which may be a low-level flat car. A pair of vehicle-carrying decks are adjustable in height to provide for either one or two vehicle-carrying levels above the lowest level, while also providing at least a prescribed amount of vertical clearance above each vehicle-carrying deck. Ramps may be provided on the lowest level at an end of the car to provide a wheel-supporting surface having a prescribed minimum height. A roof structure is light in weight, and the car has an overall height not exceeding a prescribed limit for operation on most rail lines. The ends of the car are equipped with three-panel folding doors.

  • Publication number: 20150135986
    Abstract: A railway tank car including a protective structure for the top of the tank and surrounding a manway or valve mounting nozzle to protect it against damage resulting from the car being overturned even while moving longitudinally. The protective structure may include longitudinally extending generally parallel side plates and a skid structure including longitudinally extending sloping, end portions and providing access to a manway or valve mounting assembly on the top of a nozzle. Openings may be provided in a side wall of the protective structure to give access to valve operating mechanisms extending laterally from valves. A lid for an access opening to a set of valves may include an extension that prevents a valve handle from being moved to open the valve while the lid is closed.

  • Patent number: 8291592
    Abstract: A railroad freight car with a lengthened container well, including an extended and reinforced well car unit side sill, and a method for lengthening a container well of a railroad freight car intended for carrying an intermodal cargo container. A side sill extension member is welded into position, between a body bolster at each end of the container well unit and a nearest container support assembly, and a container-well bottom assembly is lengthened at each end of the container well. A longitudinally-extending doubler plate may be welded to the longitudinally central portion of the side sill, to ensure sufficient rail clearance at mid-length of the car.

  • Patent number: 7861659
    Abstract: A lightweight hopper car that includes one or more reinforcing members at specified locations, so that the hopper car has both a carrying capacity and a structural strength comparable to those of existing, heavier hopper cars. Specifically, the present application discloses that the hopper car may be reinforced at one or more locations including (i) at selective intersections between the center sill and slope sheets of cargo wells; (ii) between side slope sheets of adjacent cargo wells; (iii) at the junction between the side sheets and end slope sheets of the hopper car; and (iv) along the end combing seal between opposed carlines, if the hopper car is covered. In addition, the present application discloses a novel means of reinforcing side sheets of a rail car, including hopper cars, against the warping that commonly occurs when welding the side sheets at the car is fabricated.
