What describes the capacity of a liquid cryogenic tank car?

• A. No fixed capacity; depends on design
• B. Varies by container construction
• C. Approximately 6300 gallons
• D. 5500 gallons

Answer: (B)

Capacity depends on the actual construction of the container. Liquid cryogenic tank cars come in different sizes and designs, and the inner tank volume—determined by its dimensions, shape, and how it’s built—varies from one car to another. Because of these design differences, there isn’t a single universal capacity for all liquid cryogenic cars; each car has its own rated capacity listed by the manufacturer. That’s why fixed numbers like 6300 or 5500 gallons aren’t universally applicable—the true capacity is specific to the particular car you’re using and is found on its data plate.
