routing, the Cardinal began operating jointly with the Chicago–Indianapolis Hoosier State. The Hoosier State operated to Indianapolis on the days the Cardinal did not, assuring seven-day service between Chicago and Indianapolis. This pattern ceased on October 25, 1987, when the Hoosier State became a full-fledged daily train once again. The Hoosier State was dropped on September 8, 1995, but resumed again on July 19, 1998, again running on days that the Cardinal did not run. 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, and brought back the Hoosier State on the pre-1999 schedule. After Indiana discontinued its subsidy, Amtrak suspended the Hoosier State as of June 30, 2019. Passengers who booked trips after that date were compensated with Cardinal tickets. Plans In the July 2010 issue of Trains magazine, the Cardinal was noted as being one of five routes under consideration for performance improvement. For the Cardinal, the proposed changes included increasing service from thrice-weekly to daily operation, and changing the western terminus to St. Louis, Missouri. Railfan and Railroad magazine also suggested that the train be rerouted to St. Louis, with a separate section bound for Chicago. In early October 2010, Amtrak released a report detailing plans to increase the Cardinals service from thrice-weekly to daily service, as well as increasing the train's on-time performance and food service. The January 2011 issue of Trains later revealed that Amtrak would scrap re-routing and Superliner conversion and instead adopt not only daily service, but also purchasing dome cars to be used along the Chicago-Washington, D.C., portion of the trip. In addition, the routing into Chicago Union Station would be changed and station platforms along the route containing coal dust would be scrubbed and cleaned. However, obstacles to a daily Cardinal persist. Track capacity is limited on the Buckingham Branch Railroad, a short line railroad between Orange and Clifton Forge, Virginia where the Cardinal operates along former C&O/CSX trackage, preventing frequent freight trains from passing a daily Cardinal. This problem also applied to the planned-but-failed Greenbrier Presidential Express train, which would also have traversed the Buckingham Branch on a weekly basis. The Buckingham Branch
