A key part of Union Pacific's public relations programs, 48 historic passenger cars and three E9 diesels make up part of the famed Heritage Fleet. Many were originally purchased for the City Streamliners, and have been carefully restored and updated to full operating condition. Today, they're finished in a modern Armour Yellow scheme, and the cars carry names of important cities, famous trains and key people in the railroad's long history. In service, these rolling goodwill ambassadors travel system-wide and beyond, behind UP's restored steam and diesel locos, to attend a wide range of public and special events every year.

• Early or Late lettering schemes as noted in two versions
• Factory-printed name with number decal for pre-1987 cars

• Modeler-installed extended drawbars for 22" radius curves included

Built as Dome Chair #7015 in December 1958, and initially assigned to the City of St. Louis, the car was formally retired in June of 1972, and passed through a succession of owners until returning to home rails in the fall of 1990. Named in honor of The Challenger, which ran between Omaha and Los Angeles, from May 1936 to April 1971.
