Built by the Union Tank Car Company, this 6500 gallon petroleum car was an early attempt to build a tank car without a full-length underframe. Short frames at each end attached the tank to the wheels and couplers. The tank itself was constructed of heavy steel plate in order to absorb the movement of the train. The stress caused by this movement made the tank flex, loosening the rivets and allowing the contents to leak. This problematic design was eliminated by welded seams on modern tank cars. It was donated in 1952 by the Union Tank Car Company.
