Amtrak retained two trains on this route: the "City of New Orleans" (which it named the "Panama Limited") and the "Shawnee". Amtrak brought back the "Illini" name on November 14, 1971, as a Chicago-Champaign train, operating in conjunction with the "Campus". It was named for the Illini, from which the state of Illinois and the Fighting Illini mascot of the University of Illinois at Urbana–Champaign get their names. Amtrak discontinued the "Campus" and "Illini" on March 5, 1972. Both trains used Central Station, which Amtrak was abandoning; Amtrak judged that the additional 35–40 minutes necessary to serve Union Station made the schedule impractical. The 1972 "Illini" made its last trip on March 3.
