Re: Nitric Acid Tank Cars

Kaminski's ACF book has a 1940 Monsanto tank car similar to the Army one and he again says the casing is designed to prevent the trapping of acid vapors.
 
Don't forget Ambroid's Riverside Oil car, which had a similar casing, but it was corrugated.

In the 1940 CBC, reprinted in Train Shed #12, ACF explains with respect to its new nitric acid tank car design,
 
"The  tank is shrouded with an open hearth steel casing, inverted "U" shaped, open at the bottom. The casing is spaced 2 in. from the tank by aluminum brackets. Vents in the dome casing prevent the trapping of acid fumes in the space between tank and casing."
 
They say the tank is aluminum alloy (hence the AL in ICC-103-C-AL) with triple aluminum riveted seams. The dome is of "special design"
