AT&SF ceased operating passenger trains on May 1, 1971, when it conveyed its remaining trains to Amtrak. These included the "Super Chief"/"El Capitan", the "Texas Chief" and the "San Diegan" (though Amtrak reduced the "San Diegan" from three round trips to two). Discontinued were the "San Francisco Chief", the ex-"Grand Canyon", the "Tulsan", and a Denver–La Junta local. ATSF had been more than willing to retain the "San Diegan" and its famed "Chiefs." However, any railroad that opted out of Amtrak would have been required to operate "all" of its passenger routes until at least 1976. The prospect of having to keep operating its less successful routes, especially the money-bleeding 23/24 (the former "Grand Canyon") led ATSF to get out of passenger service altogether.
