Abstract: A transverse trough coil car has a sawtooth center sill. It has a pair of truck centers. Portions of the straight-through center sill deviate upwardly inboard of the truck centers and define saw teeth that have truncated tips. The center sill has an undulating top cover plate, or top flange. A portion of the center sill deviates slopingly to conform angularly to the inclined sides of the transverse troughs. The center sill is notched to conform to those transverse troughs. The car has stub bolsters that are surmounted by pre-fabricated trough assemblies that mate with the stub bolsters and extend to the side sills. The center sill has an array of internal web separators and gussets to discourage buckling. There are deep center sill webs that extend upwardly higher than the draft sill.

Abstract: A well car for carrying shipping containers has a pair of end structures supported by railcar trucks, a pair of first and second spaced apart side beams extending between the end structures and a well defined therebetween. Container support cross-members are mounted between the side sills in a position to support an end of a shipping container load carried within the well. An array of elongate members is provided to divide the opening into smaller spaces and to prevent excessively large openings from being left. The elongate members can have different forms, whether rigid hollow structural sections, rods, or cables. The arrays of elongate members are oriented at oblique angles along the railcar body.

Abstract: There is a damper wedge for a railroad car truck. It has a removable and replaceable friction element that reciprocates on the wear plate of the side frame column of the railroad car truck. It has a non-metallic wear surface; a spring seat that, in use, engages a spring of the railroad car truck; and an inclined damper wedge surface having a primary angle, alpha, and a secondary angle, beta. The inclined damper wedge surface has a curvature. The curvature has a working point. The working point is located in a central region of a contact patch, or working surface patch. The nonmetallic wear surface material is mounted to a carrier that mounts removably to the damper wedge body. The carrier has fingers that span the wedge and that transfer shear and resist torsion, the fingers preventing the non-metallic member from migrating out of position.

Abstract: A railroad hopper car body includes a set of hopper and hopper discharges. Egress of lading from the discharges is governed by movable doors that swing between a closed position and an open position. The motion is driven by a mechanical transmission that is itself driven by an actuator. Each pair of doors is driven by a single actuator. The actuator is mounted to act through the center sill. A portion, or substantially all, of the actuator may be mounted in a predominantly squat, vertical orientation within the center sill. In alternate embodiments, the transmission output may be bifurcated. The center sill bottom flange may be narrower adjacent to the doors. The mechanism may have a secondary lock. The mechanism may have an auxiliary manual release.

Abstract: A rail road freight car truck has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The mounting interface between the ends of the axles and the sideframe pedestals allows lateral rocking motion of the sideframes in the manner of a swing motion truck. The lateral swinging motion is combined with a longitudinal self steering capability. The self steering capability may be obtained by use of a longitudinally oriented rocker that may tend to permit resistance to deflection that is proportional to the weight carried across the interface. The truck may have auxiliary centering elements mounted in the pedestal seats, and those auxiliary centering elements may be made of resilient elastomeric material. The truck may also have friction dampers that have a disinclination to stick-slip behavior. The friction dampers may be provided with brake linings, or similar features, on the face engaging the sideframe columns, on the slope face, or both. The friction dampers may operate to yield upward and downward friction forces that are not overly unequal. The friction dampers may be mounted in a four-cornered arrangement at each end of the truck bolster. The spring groups may include sub-groups of springs of different heights.

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.

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.

Abstract: An autorack railroad car has a housing surmounting an underframe. The underframe defines a first or main deck. The housing, or “rack” defines at least one additional deck spaced upwardly from the main deck. The housing has end doors. The end doors may be folding end doors, such as a tri-fold hinged door. When closed, the door may be secured by latches at top and bottom. The car may have a movable sill-step, or foot-hold that is movable between a deployed or extended position, and a stowed or retracted position. The movable step may be mounted to a panel of the door. The movable step may be biased away from any position between the stowed and retracted positions. The movable step may be free of springs that may break, and free of pins or other items requiring careful removal and replacement. The movable parts of the step assembly may be captured by the stationary parts to prevent them from coming loose or falling off.

Abstract: An autorack railroad car has a housing surmounting an underframe. The underframe defines a first or main deck. The housing, or “rack” defines at least one additional deck spaced upwardly from the main deck. The housing has end doors. The end doors may be folding end doors, such as a tri-fold hinged door. When closed, the door may be secured by latches at top and bottom. The car may have a dynamic response member, such as a damper, or stop, mounted between one or more panels of the door and the adjacent end of the deck. The dynamic response member may function either to provide damping to the door in vibration, or may function to define a vibration nodal point intermediate the main deck and the roof, or both.
