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.

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.

The stake pockets are collapsible from a deployed position to a storage position. The stake pockets are mounted on doublers that mount to the side walls of the car in line with the side wall stiffeners and their associated cross-bearers. The connection between the stake pocket and the doubler is deliberately made weaker than the connection between the doubler and the side wall such that under abusive loading conditions the stake pocket may tend to shear off the doubler, and may tend thereby to leave the side wall less damaged than might otherwise be the case.

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.

A railroad freight car has lifting apparatus at the body bolsters of the car. In addition it has lifting interface members mounted to underlie the side sills near the wheel-well cut-outs of the side beams. The lifting interface members stand downwardly proud of adjacent structure and fasteners heads, such that when lifting apparatus, such as a hydraulic lift, is brought to bear it contacts the lifting interface member first, rather than damaging adjacent structure, be it the side sills themselves, lateral cross-members such as cross-bearers and cross-ties, or diagonal struts. It may also tend to prevent consequent damage to the end bulkheads. The lifting interface members may permit the replacement of wheelsets in the field. The lifting members may be sacrificial, such that they may be replaced when worn or damaged.
