Built by American Car & Foundry Company for Monsanto, this 8,000 gallon,
double hull car was designed for transporting concentrated nitric acid, which is
extremely corrosive. The inner tank is constructed of an aluminum alloy
which is protected by a cushion of air and a steel outer shell.
Private car MCHX #117 was donated in 1961 by the Monsanto Chemicals Company.
Did You Realize: : Of MOT's many artifacts, Frisco #1522 may be the best-known and best loved,
thanks to its modern day restoration and return to service, hauling popular special passenger
excursions through the Midwest and other parts of the country from 1988 until 2002.
