Super Chief
The Sante Fe combined the "Super Chief" and "El Capitan" on January 12, 1958. The combined train used the "Super Chief"'s numbers, 17 and 18, but the Santa Fe continued to use both names. On its formation Amtrak continued the combined "Super Chief"/"El Capitan" designation until April 29, 1973, when it dropped the "El Capitan" portion. Today the route of the "El Capitan" is served by Amtrak's "Southwest Chief". Many Amtrak trains used a combination of refurbished former Santa Fe Hi-Level cars with newer Superliner railcars until the early 2000s.
