Following World War II, specialized liquid shippers requested new special duty tank cars, and General American Transportation Corporation met their demands by producing specific-service cars such as this 8,000 gallon acid service tank car. At the same time, General American switched from a riveted underframe and riveted tank design to a welded underframe and tank. While General American’s factory in Sharon PA manufactured at least three different post-war versions of 8,000 gallon acid all-welded tank cars, these specific prototypes were produced between 1949 and 1960. Like all Tangent Scale Models offerings, these tank cars had long service lives, lasting well into the 1980s in revenue service. Acid service tank cars were commonly-seen nationwide, providing transportation for strong chemical compounds, such as hydrochloric (muriatic), hydrofluoric, phosphoric, and sulfuric acids. Acid tank cars were rubber-lined, featured one percent expansion domes on the top, and did not have bottom tank outlets.
