Abstract: A railcar system that includes a railcar and a nested sliding gate assembly disposed within the railcar. The nested sliding gate assembly includes an upper deck, a lower deck, and a driving system. The upper deck has a plurality of holes. The lower deck is positioned below the upper deck and has a plurality of discharge ports. The driving system positions the lower deck in a first position with respect to the upper deck, where the holes of the upper deck and the discharge ports of the lower deck do not align when the lower deck is in the first position. The driving system also positions the lower deck in a second position with respect to the upper deck, where the holes of the upper deck and the discharge ports of the lower deck at least partially align when the lower deck is in the second position.

Abstract: The present invention relates to an equipment envelope (10) for a hopper wagon. The equipment envelope comprises a housing (11) that is configured to define an enclosed cavity storage space (12) in a bulk commodities storage chamber of a hopper wagon body, in which hopper wagon control means and/or other component parts of the hopper wagon (30) can be housed for use. The equipment envelope may be configured to be arranged in the chamber such that it is located above a hopper wagon bogie (40), preferably adjacent a closable outlet. The equipment envelope may comprise a first end wall (111) that is configured to extend at a predetermined incline angle α towards the outlet. Depending on the configuration of the hopper wagon, the equipment housing may be configured to be located adjacent a further or alternative closable outlet. The equipment envelope may comprise a second end wall (112) that is configured to extend at a predetermined incline angle β towards the further outlet. The first end wall and second end may be configured to meet at an apex (14) such that the equipment envelope has a cross-sectional profile of a triangle, preferably a scalene triangle. A further aspect of the present invention relates to a hopper wagon comprising at least one equipment envelope.

Abstract: A baffle comprising a panel body that is mountable on a wall of a hopper adjacent to an edge of an outlet of a hopper and is arrangeable in a projecting position, to project in a generally downwardly direction beyond the edge of the outlet so as to restrict the spread of bulk commodities past the panel body as the bulk commodities discharge through the outlet. The panel body is arrangeable in the projected position to project in a generally downwardly direction beyond the edge of the outlet and between a gap space defined by the edge of the outlet and an outlet cover arranged in an open position. The baffle may comprise rotatable mounting means for rotatably mounting the panel body on the wall of the hopper such that the panel body is movable between the projected position and a retracted position, where the panel body is arranged so as to provide a minimal or no barrier effect. The baffle may comprise drive means to drive the panel body between the projected position and the extended position. The drive means may be self-actuating means and the self-actuating means are optionally configured to incite the rotation of the panel body between the projected position and the retracted position as the outlet cover moves between an open position and a closed position. The self-actuating means may comprise slidable coupling means for slidably coupling the panel body to the outlet cover and optionally the slidable coupling means comprise one or more low friction contact members mounted on a lower edge and/or side edge of the panel body and arranged in mating contact with the outlet cover.

Abstract: A railroad hopper car discharge outflow is controlled by closure members, at least one of which is movable. The closure members (or doors) are hingeless, being mounted on four bar linkages, such that the distal edge of the doors sweeps predominantly horizontally while the proximal edge of the door moves predominantly upwardly. The doors move through noncircular arcs, such that the size of the vertically projected door opening is abnormally large compared to the clearance heights of the door during opening and closing. The doors are driven by a transverse drive linkage that is driven by a transversely mounted actuator. The actuator may be mounted in an accommodation in the lee of slope sheets between adjacent hoppers in a mid-span portion of the car. Drive from the actuator is carried to a pair of symmetrically mounted doors through drive train linkages.

Abstract: A hopper car has arcuate side sheets that are bent over the forming members of the structure to give a generally outwardly bulging shape. The upper margin of the side sheet is kinked inwardly of the radius of curvature of the larger portion of the side sheet more generally, such as may tend to impose a bending moment on the large, relatively thin side sheet panels. This may in turn tend to urge or bias those panels to a bulging position or shape, rather than a sagging, deflected, or inwardly dented position.

Abstract translation: 料斗车具有弓形侧片，其弯曲在结构的成形构件上，以形成大致向外凸出的形状。 侧板的上边缘更一般地侧向侧面的较大部分的曲率半径向内弯曲，这可能倾向于在大的相对薄的侧板上施加弯曲力矩。 这又可能倾向于将这些面板推向或偏压到凸出位置或形状，而不是下垂，偏转或向内凹陷的位置。
