摘要： A railroad box car has a combined underframe and floor structure that includes a floor sheet having an upper surface upon which to carry lading, and an underside to which a center sill, cross-members, and floor stringers are welded. The floor sheet defines the upper flange of the center sill, the cross-members, and the stringers, such that the center sill, cross-members, and stringers are mutually flush. For assembly, the floor sheet is upside-down, and the center sill webs, stringers, and tie-down mounting rails to it with longitudinal welds. The cross-members and center sill web separators are positioned cross-wise and welded in place. The floor sheet is a non-nailable surface that caps the underframe structure. The stringers are channels welded toes-in to the underside of the floor sheet with the spacing between the center sill web, stringer toes, and edge channel rails being roughly equal.

摘要： A symmetrical multi-unit railroad freight car, such as a 3-pack railroad intermodal well car, has body units that are connected symmetrically. The body units have a symmetrical arrangement of end trucks and shared trucks. The end trucks are 70 Ton Trucks. The shared trucks are 125 Ton trucks. The trucks have passive steering using geometric rocker stiffnesses. The rockers in the end trucks have a smaller radius of curvature than the rockers in the shared trucks. The spring groups in the shared trucks are stiffer than the spring groups in the end trucks. The spring groups in the end trucks have a different proportion of damping when empty, a shorter live load range of travel, and greater reserve travel than the shared trucks. The end trucks and the shared trucks have four-cornered damper groups that have the same sized damper wedges. The damper wedges have non-metallic wear pads.

摘要： A railroad hopper car has a hopper carried between two trucks, and has convergent end and side slope sheets that feed a bottom discharge. The bottom discharge has a rectangular frame. The bottom discharge is lower than the center sill. The car has a flat bottom discharge having multiple arrays of louvers. All of the lading discharges through the flat bottom. The side sheets extend downwardly beyond the side sills, so that the side slope sheets terminate below the side sills. The car has laterally extending shear force transfer members, that provide a shear connection between the side walls of the car, and have openings to permit lading from the main containment volume of the car to pass therethough to the lading discharges. The louvers are joined to move together. Alternatively, the gate may include two opposed sliding doors separated by a beam that runs under the center sill.

摘要： A transverse trough coil car has a straight-through center sill. It has a pair of truck centers. It has a set of trough slope sheet assemblies mounted to the center sill between a pair of side sills. The slope sheet assemblies include intermediate slope sheet assemblies that are pin jointed connected to the center sill. The pin joint connection has a tongue and clevis form that is aligned with the webs of the center sill. The car may have stub bolsters that are surmounted by pre-fabricated trough assemblies that mate with the stub bolsters and extend to the side sills.

摘要： A rail road car truck has a bolster having the form of a hollow beam that has a deep central portion and shallow ends. The bolster has a top flange, a bottom flange and internal and external webs extending between, intersecting and merging with the top and bottom flanges. A center plate bowl is located in the middle of the top flange, and brake rod passages are defined transversely through the bolster. In some embodiments, transverse ribs run underneath the center plate bowl. The ribs may be curved. The ribs may be flush with the brake rod openings in the various webs. There may be upwardly standing ribs running transversely across the bottom flange. Those lower ribs may terminate upwardly flush with the brake rod openings. Alternatively, the bottom portion of the bolster may by cast with a greater thickness, up to the bottom of the break rod openings. In other embodiments, the bolster may have partial or fully tubular brake rod opening liners or tubes that extend across the bolster beneath the center plate.

摘要： A railroad car truck for a railroad freight car, such as an autorack car, has a bolster mounted cross-wise between two sideframes. The bolster ends are mounted on respective spring groups carried by the sideframes. The bolster can translate laterally relative to the sideframes. The side frames are mounted to swing laterally relative to the wheel sets, and hence relative to the rails. Resistance to lateral deflection is provided by the resistance of the sideframes to the pendulum swinging motion, and by shear in the spring groups. The truck has a doubled damper arrangement of dampers in a four-cornered layout at each end of the bolster, giving a flexing resistance to yaw between the sideframes and the bolster ends. The doubled damper arrangement works against large wear plates mounted on the sideframe columns. The large wear plates are mounted normal to the dampers and square to the sideframes.

摘要： A hopper car discharge outflow is controlled by closure members, at least one of which is movable. The 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. The doors are driven by a longitudinal shaft that is mounted within the center sill. It drives a set of single input, double output bell cranks that drive adjacent pairs of doors, and that employs an over-center toggle to hold the doors in the closed position when the car is laded. The actuators may be mounted in shelters midway along the car, and may be offset from the centersill. The actuators may be mounted predominantly vertically such that gravity may obviate the need for a secondary lock. The doors of a transverse car need not all be of the same size. The over center may include a manual release having a fulcrum with a progressive decrease in mechanical advantage.

摘要： A hopper car discharge section may be wide at the top and narrow at the bottom. Outflow is controlled by movable closure members. The hopper car has a plurality of hoppers of which two hoppers share a common ridge assembly. The ridge assembly forms a common mating and fit up location for the upper margins of the slope sheets of two lengthwise adjacent hoppers. The ridge assembly includes an horizontal center section and two end plates that angle upwardly outboard toward the top chords of the side walls. The ridge assembly stands proud of the upper margin of the respective adjacent slope sheets. A gusset is mounted between the adjacent slope sheets below the ridge plate such that the slope sheets and gusset form a reinforcement tube running across the car, the end plates forming the stems of a vertical T-section attached to the side wall and overlapping the top chord.

摘要： A railroad tank car may have external fittings, such as a bottom opening valve, that protrude from the bottom of the tank car tank. In a derailment the tank car tank may meet the ground. A tank skid plate assembly has an accommodation in which to shelter such fittings. The skid plate assembly has a shell with tapered ramps at either end. It mounts to tank reinforcement structure, such as reinforcing bars. Reinforcements may be mounted in the lee of the shell. Those reinforcements may be mounted to the shell only, without welding connection to the tank car tank. The reinforcements may be, or combine with the shell to define either a bridge or a truss that spans the space between the reinforcement bars. The assembly may have an access passageway, such as for admitting a heating pipe. The assembly may include lateral and longitudinal internal webs for providing crush resistance.
