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.
