Age of Steam Roundhouse Museum’s 11,000 gallon tank car was originally owned by Hercules Powder Company. Hercules was a well-known manufacturer of gunpowder. The company – began as a division of DuPont – employed a fleet of tank cars (supplemented by many others leased from Union Tank Lines and General American Tank) to transport raw materials to their factories. Tank cars in service for Hercules generally carried resin or glycerin.

Tank car 88208 was meticulously cleaned and restored to its original appearance in late 2020. The car now features the distinctive Hercules Powder Company logo, a depiction of the Roman mythological figure.
