Enjoy the fall colors and travel back in time to the private Pullman train car, the Constitution. Built in 1905, it served as "Air Force One" for presidents Harding and Wilson. The original car consists of four state rooms, an observation deck, a dining room, and a galley. Two large living rooms with fireplaces, a master bedroom and bathroom have been added on. When the president of Illinois Railway Museum visited, he said it was the most well-preserved Pullman train car in the U.S.
