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.
