I've heard numerous of times that the Santa Fe considered to run the Super Chief/El Capitan and the Grand Canyon well after 1971. However, I really haven't found anything that wasn't speculative about the Santa Fe not joining Amtrak. Has anyone found anything that seems this belief is legitimate? If so why? My understanding is the Rio Grande did so due to fear of congestion on the Moffett Route, did the Santa Fe go to this philosophy or was it more like the Southern's use of prestige?
