A cargo restraint panel may comprise a foam core and one or more side caps covering one or more sides of the foam core. A side cap may protect a side of the foam core covered by the side cap. A side cap may comprise a ridge that allows the side cap to compress.

Bumper guard and side post guard apparatuses prevent vehicles from being damaged when stored and transported within an auto-rack railcar, such as when vehicle doors are opened, where vehicle doors may otherwise contact the side panels and side posts of the auto-rack railcar. Methods of using the same are further provided.

A universal chain tie down assembly includes an anchor base and an associated turret, with a cannon pivotally connected to the turret. The proximal portion of a tensioning rod is associated with the cannon. The tensioning rod further includes a distal portion associated with a hub, along with a tool attachment portion that is configured for engagement by a tool for rotation of the tensioning rod. First and second arms of a constant tensioning device extend from proximal ends associated with the hub to distal ends spaced distally of the hub. A chain is associated with a distal end of the constant tensioning device, such as by being linked to the curved portion of a U-bolt of the constant tensioning device. A tension lock assembly and/or an anti-vibration assembly may be employed to prevent a vibration-induced change in the tension in the universal chain tie down assembly.

According to some embodiments, a modular railcar comprises: a pair of trucks disposed near each end of the modular railcar; an underframe coupled to the pair of trucks and supported by the pair of trucks. The underframe comprises a plurality of coupling apparatus. The plurality of coupling apparatus are configured to couple a modular top container to the underframe. According to some embodiments, a modular top container comprises: a floor panel configured to transport a lading; and a plurality of coupling apparatus coupled to the floor panel. The plurality of coupling apparatus are configured to couple the modular top container to a modular railcar. The floor panel is configured to support the weight of the lading when detached from the modular railcar.
