I purchased and received in the mail the book titled Tank Car Capacities Tariff, Freight Tariff 300-H, from 1955, showing capacities of tank cars. The book was digitized by Ian Cranston and reproduced by Lulu. The book provides the capacity of a tank car in gallons for the shell and dome. I do not understand why the gallons would need to be split between the two rather than just the total of the two together. Does someone know what the purpose of providing numbers for the shell and dome separately was? Thank You in advance for your time and effort to help.
The shell capacity is the actual amount you can ship in the car; the dome capacity allows you to calculate the percentage available for expansion, so you can adjust the amount you load if the expansion is not adequate for your particular commodity.
