What is the capacity range for pressure and non-pressure tank cars?

• A. 4000-45000 gallons
• B. 1000-10000 gallons
• C. 100-500 gallons
• D. 50000-60000 gallons

Answer: (A)

Tank cars come in a range of sizes, but the typical internal capacity for both pressure and non‑pressure designs is about 4,000 to 45,000 gallons. The lower end covers smaller or specialty pressure tanks, while the higher end includes the standard large non‑pressure tanks used for many liquids. Remember that capacity is the volume the tank can hold, not the weight it’s permitted to carry—the weight limit is a separate specification. While there are some outliers in the field, this broad range reflects the common capacities you’ll encounter with rail tank cars.
