Abstract
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.
