Abstract: A uniquely designed two piece bulkhead door for box cars in the railroad industry. The bulkhead door is made of steel side frame members and steel frame cross members using ultra-high strength resilient steels and includes a plurality of "slide in" impact and chemically resistant thermoplastic composite modular panels. This device is used to restrain, secure and separate cargo in freight railroad cars. This load divider presents a number of exceptional features such as light weight construction, modular design, an ergonomically designed handle and structurally effective hardware. The bulkhead door fulfills the impact resistance performance requirements.
