Abstract
A tank car head shield is generally arcuate and is located outboard of the tank. The shield extends upwardly from the center sill to the top portion of the tank and outwardly to protect the entire tank head. A head shield anchor extends generally horizontally from the shield to a location generally on the horizontal portion of the top of the tank, and circumferentially on either side of the tank and down to the center sill. The head shield anchor is continuous. First connecting means connect the head shield to an outer portion of the anchor outboard of the tank. Second connecting means connect an inner portion of the anchor to the tank. Third connecting means connect the shield and/or anchor to the center sill. In one embodiment the first connecting means comprises an angle welded to the anchor and to the head shield and the second connecting means comprises a pad welded to the anchor and to the tank. The anchor pad may be discontinuous. In another embodiment of the invention cushioning material is provided between the tank and head shield to cushion any impact loads applied to the shield.
