Hazardous Materials: Improving the Safety of Railroad Tank Car Transportation of Hazardous Materials

Notice of proposed rulemaking (NPRM).
The Pipeline and Hazardous Materials Safety Administration and the Federal Railroad Administration are proposing revisions to the Federal Hazardous Materials Regulations to improve the crashworthiness protection of railroad tank cars designed to transport poison inhalation hazard materials. Specifically, we are proposing enhanced tank car performance standards for head and shell impacts; operational restrictions for trains hauling tank cars containing PIH materials; interim operational restrictions for trains hauling tank cars not meeting the enhanced performance standards; and an allowance to increase the gross weight of tank cars that meet the enhanced tank-head and shell puncture-resistance systems.
