Shipping liquefied natural gas (LNG) by rail tank car is a viable mode in U.S. regions where the natural gas pipeline network is limited. Before the first bulk shipment of LNG by rail tank car, the National Academies of Sciences, Engineering, and Medicine recommends a review of the research and testing done so far on safety assurance, especially for the design of the tank car, and follow up with activities if warranted.
TRB Special Report 345: Preparing for LNG by Rail Tank Car: A Readiness Review, from TRB and NASEM, focuses on safe train operations, support for emergency responders, and design features of the new cryogenic tank car, including pressure relief devices, insulation, and the type of outer tank steel.
