By May 1, 1971, the startup date of Amtrak, Central was used only by trains of the Illinois Central Railroad (including the "City of Miami", "City of New Orleans" and "Panama Limited" on the line south from Chicago, and the "Hawkeye" on the line to the west) and the Cleveland, Cincinnati, Chicago and St. Louis Railway (Big Four) (including the "James Whitcomb Riley" and "South Wind"). Amtrak continued only the "City of New Orleans", "James Whitcomb Riley" and "South Wind", as well as the IC's local "Shawnee".
