In June 1942, Union Pacific built this 40 ft box car with single door at their Omaha, Nebraska shops. It was painted UP mineral red and lettered in yellow. The class B-50-33 box car was part of a 749-car fleet that was emblazoned on one side with the slogan, 'Be Specific - Ship Union Pacific' and on the opposite side with the other UP slogan common in that era, 'Road of the Streamliners.'
