摘要： A railroad hopper car having a single cargo-receiving hopper extending over substantially the length of a car body having a cargo discharge portion occupying most of the available distance between the wheeled trucks supporting opposite ends of the car body. The car has no pair of slope sheets separating longitudinally-adjacent hoppers and defining unusable space beneath the slope sheets, and so the overall length of such a hopper car capable of carrying a desired volume of cargo can be less than that of one with multiple separate hoppers. Cargo discharge openings are arrayed along the length of the cargo discharge portion, and a unitary multi-gate assembly is supported within the cargo discharge portion of the car body so as to be movable longitudinally of the car body to open or close all of the cargo discharge openings simultaneously.

摘要： Subassemblies for railroad tank cars are herein disclosed. In some embodiments, the subassembly includes a center sill including a generally horizontal top member and a pair of upright side plates spaced apart laterally from each other and a head brace having a lower margin welded to the top member of the center sill and an upper margin welded to the head of the tank. Each of the side plates having a top surface and an opposed bottom surface, the top surface being planar within a longitudinal central portion and at least a substantial part of a first longitudinal end portion. The bottom surface is planar and parallel to the top surface within the longitudinal central portion and a second longitudinal end portion. At least a substantial part of the bottom surface within the first longitudinal end portion has a shape that includes or approximates one or more radiuses of curvature.

摘要： Railroad hopper cars and methods of increasing total volume capacity of a railroad hopper car having a car body with two or more hoppers. In one embodiment, the railroad hopper car includes a car body having a pair of opposed sides and a pair of opposed ends defining a length. The hopper car additionally includes a pair of wheeled trucks supporting the car body. The hopper car further includes two or more spaced bulkheads extending between the pair of opposed sides to define three or more separate hoppers arranged adjacent one another along the length of the car body and between the pair of side walls. The hoppers being longitudinally asymmetric such that total volume of the hoppers on one side of a transverse center plane of the car body is different from total volume of the hoppers on the other side of the transverse center plane.

摘要： Articulated connectors are attached to and extend from center sills of adjacent car units of a multi-unit railroad freight car, connecting the car units to each other and to a shared truck. The center sill of each of the car units includes a top member that is of increased thickness at the outer end of the center sill. A weld extending along a shoulder that extends around the main body of s portion of the articulated connector attaches the articulated connector portion to the outer end of the center sill with ample strength to carry draft and buff train loads as well as the weight of the car unit and its lading, without the need for weld joints inside the center sill.
