Caveats: NONE Guys; 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. Elden Gatwood

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: http://en.wikipedia.org/wiki/File:Ducktown_train.jpg 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.

Apparently the harvesting machines work better when the vines are dead and dried out. Acid from ASARCO in El Paso went to Royalton, Minn. for example.
