LH2 tank cars with a capacity of are used for transcontinental transport. Design The pressure within the tank is or lower with a temperature below 20.27 K () and a boil-off rate of 0.3% to 0.6% per day The tank is double walled like a vacuum flask with multi-layer insulation, with the valves and fittings enclosed in a cabinet at the lower side or end of the car. Classes Cryogenic liquid tank cars in the USA are classified as follows: * DOT-113 tank cars (Cryogenic liquid tank cars) * AAR-204W tank cars (Cryogenic liquid tank cars) * AAR-204XT (Inside boxcar) See also * Association of American Railroads (AAR) * Compressed hydrogen tube trailer *Hydrogen economy * Hydrogen infrastructure * Liquid hydrogen tanktainer * Liquid hydrogen trailer * United States Department of Transportation (DOT) *Vacuum flask ...
