A key part of Union Pacific′s public relations programs, 48 historic passenger cars, three restored steam locomotives and an A-B-A set of E9 diesels make up the famed Heritage Fleet. Many were originally purchased for the City Streamliners, and have been carefully restored and updated to full operating condition. Today, the cars and E9s are 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, to attend a wide range of public and special events every year. Perfect for fan trip and excursion service UP excursion schemes Factory-printed car names, numbers and full-color graphics as appropriate Factory-installed grab irons Prototypically accurate window tinting Correct 36′ turned metal RP-25 wheels Proto MAX(TM) metal knuckle couplers PLEASE NOTE: As these cars are the correct prototype length and feature full underbody detail to match the prototypes, a minimum 24′ radius is recommended for operation. Built by St. Louis Car in 1962 as a postal storage car, number 5769 was reassigned to a proposed but short-lived express service in 1969, and transfered to the maintenance fleet in 1970. Renumbered to #904304 in 1973, it was refitted as a rolling shop to support the Heritage Fleet steam excursions in 1981.
