By 1971 the once-proud Eagle fleet had shrunk to only one survivor. This is the timetable for the last named passenger train operated by the Missouri Pacific Lines. To be complete, it must be noted that this train shared the time card with two more trains: An unnamed St. Louis-Kansas City local and a by-then-nameless Trains 1 and 2, the former Texas Eagle, which still ran from St. Louis as far as Texarkana.

When Amtrak assumed responsibility for intercity passenger service on May 1, 1971, it would retain service over Missouri Pacific's line from St. Louis to Kansas City and in fact would tie it in with service to the east, providing direct through service from Kansas City to New York City. While this through service would not survive the Carter cutbacks at the end of the '70s, service over the St. Louis-Kansas City route would be retained and even expanded in the '80s with the addition of the St. Louis/Kansas City Mules (which somewhat unfortunate names were adopted at the insistence of the Missouri state legislature, which financed the service).
