What is an identifying feature of a cryogenic liquid tank car?

• A. Mostly white
• B. Double Doors
• C. Tank within another Tank
• D. labeled refrigerated or labeled as liquid gas

Answer: (D)

The key point is that cryogenic liquid tank cars are identified by explicit labeling that they are refrigerated or contain liquid gas. This labeling communicates the exact nature of the load and the hazards, which is what responders and handlers need to know. Visual cues like color aren’t standardized and can vary, so they’re not reliable identifiers. Features such as double doors aren’t typical for cryogenic cars, and while there is an insulated design (tank inside an outer protective jacket), that detail isn’t used as the primary identifying feature in the field. So, labeling that it’s refrigerated or liquid gas is the most direct and dependable indicator.
