This has been suspected for a while now, but Amtrak has made it official. Starting on November 10th the Capitol Limited will be combined with the Silver Star to form a new route called the Floridian (train 40/41). This will run daily from Chicago to Miami with stops in Orlando and Kissimmee using the Viewliner trains.
