With the Indianapolis routing, the Cardinal began operating jointly with the Chicago—Indianapolis Hoosier State. The Hoosier State operated to Indianapolis on the days the Cardinal does not. This pattern ceased on October 25, 1987, then resumed again on July 19, 1998. On December 17, 1999 Amtrak extended the Hoosier State to Jeffersonville, Indiana (and later to Louisville, Kentucky) and renamed the train the Kentucky Cardinal. This new train was a daily service; on days when the Cardinal operated, the two trains ran combined between Indianapolis and Chicago. Amtrak ultimately discontinued the Kentucky Cardinal on July 4, 2003.
