Re: chlorine cannister flats (was Virginia Chemical Tank Cars)

For some strange reason I have been collecting information about these cars for awhile now. Here's what I have:

Initial builds by ACF started in the 1920's and production lasted to just before 1950. General American Car Co. and Standard Steel Car Co. also produced similar cars during this same time. Carrying capacities of these cars ranged from 60,000 to 80,000 pounds and had a capacity of fifteen horizontally mounted tanks. These cars were used by Columbia Alkali Gas Co., Hooker Chemical Co., E.L. Dupont and others. Some of these cars lasted until the 1990's. Main purpose was to provide chlorine to water treatment plants but had other uses as well.

SHPX 222 is identified as AAR type FM (flat general service); similar cars have also been denoted as AAR type TMU (tank multiple unit) because these cars really don't function as flat cars for any lading except removable, high pressure gas cylinders. These cars were used to handle acid gases like chlorine for customers without direct rail service or the inability to unload and store a full tank car load. The last large-scale user of this system is Department Of Defense. Many outdated chemical weapons materials traveled their last miles in these unusual tank cars. This car has been imported in brass at least 3 times in the last 30 years and was actually a "dollar model" project in Model Railroader magazine.
