  • Publication number: 20100024680
    Abstract: A joint connecting a container corner support assembly to a body bolster and a connecting assembly portion of an end of a container well unit in connection with shortening a container well of a railroad freight car intended for carrying an intermodal freight container. A connector member is welded into position, between a transverse gusset plate of a container corner support assembly and a closure plate of a connecting assembly, to transmit forces between the gusset plate and the connecting assembly associated with a body bolster in an end of the container well unit.

  • Publication number: 20080035014
    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.

  • Publication number: 20030070577
    Abstract: A multi-unit railroad freight car and a container-carrying bridge unit for such a car. The bridge unit extends between and is carried on the adjacent body bolsters of both of a pair of drawbar-connected well units designed for carrying stacked cargo containers. The bridge unit includes a center sill, a transverse bolster at each end of the center sill, and container-supporting arms extending from the bolsters and above the body bolsters of the adjacent container well units to support a cargo container.

  • Patent number: 6324996
    Abstract: A structural assembly defining a corner of a doorway for a railway boxcar in which a square-cornered doorway opening is provided and yet stress concentrations are avoided. A corner connecting member interconnects upright and horizontal doorway frame structures, but instead of including an angular intersection of vertical and horizontal surfaces defining the doorway opening, the corner member includes an arcuate concave connecting surface extending between the upright and horizontal surfaces defining the doorway opening. The arcuate concave connecting surface is located outside the doorway opening and extends around the location where the vertical and horizontal surfaces would intersect, so that there is no angular intersection to concentrate stresses. An insert fits matingly along the arcuate concave connecting surface and has an inside corner defined by surfaces that are located to extend the vertical and horizontal surfaces and define the corner of the doorway opening.
