What is the typical capacity range for Cryogenic Liquid Tank Cars?

The typical capacity range for cryogenic liquid tank cars is indeed between 4,000 to 20,000 gallons. This range is reflective of the design and operational requirements for transporting materials that need to be kept at extremely low temperatures, such as liquefied natural gas (LNG) or liquefied oxygen. Cryogenic tank cars are specially constructed to maintain these low temperatures to prevent the contents from vaporizing and to ensure safe transport.

Other options do not accurately reflect the standard capacities of cryogenic liquid tank cars. For instance, while 1,000-5,000 gallons is too low for standard cryogenic tank cars, 10,000-30,000 gallons exceeds the typical capacity and is not commonly utilized for cryogenic transportation. Similarly, the 50,000-100,000 gallon range is size-wise far beyond the design limits for these types of tanks, as such large capacities are usually reserved for other types of bulk materials, not cryogenic liquids.
