The American Viscose Company, at Lewistown on my PRR Middle Division, was a manufacturer of rayon. It once employed over 3,000 people and eventually closed when Hurricane Agnes flooded the plant in 1972.
One of the raw materials for the manufacture of rayon is sodium hydroxide, more commonly known as "caustic soda". To prepare waybills, I used the Waybill and IndMan (free) applications from Shenware and the industry database (also free) from the OpSIG, I got a list of providers of caustic soda. One was Hooker Chemicals in Wilmington, CA.
I recalled the bright orange Hooker cars from previous releases. They typically had sources of Niagara Falls, NY. Then I recalled a recent run by Tangent Scale Models. As luck would have it, I hit the trifecta -- they were still in stock, they had a source of Wilmington, CA, and they were lettered for caustic soda!
These are the details that only a railroad owner usually appreciates. But, hey, I know it's accurate!
While I was at it, I added a general service GATX tank to fill out the order. Here they are at Lewistown:
