Re: 40's era tank cars for sulfuric acid loading (UNCLASSIFIED)

Early acid cars include variations on the Type 21, pre-war versions from
GATC, and others.

Hydrochloric and sulphuric were used in de-scaling and pickling steel sheet
and plate, and also forge products, so you might see cars hauling it in many,
many locations.

Many acids were shipped in 103-B cars, which had rubber liners, 1% domes, and
top loading/unloading arrangements.

I have only seen one acid car in HO scale, and it is a late (c. 1960?) welded
ICC-103-B-W GATC car from Lambert.

We could very much use an earlier model of the acid cars. Even a conversion
kit would be nice.

Acid tanks have hauled acid in and out of smelters and copper refineries
since the early days, long before air pollution laws. The smelters around
Ducktown, TN went to acid recovery in 1904, because acid was a valuable
by-product of sulfide ores. And also because acid emissions made the
landscape look like this:

Yes, that is Tennesee. Notice the freight car. The area around Wawa, Ontario
looks similar, from the past roasting of iron sulfide ores.

Acids are used as the electrolyte in electrolytic copper refining, which may
or may not be done at the same site as the smelter.

Among other uses, sulfuric acid is shipped to potato growing regions where
it is sprayed on the vines shortly before mechanical harvesting to kill the
