The Chattanooga Choo Choo Hotel is located in the old Terminal Station. You can book a room in an actual train car, if you want. I read up on the history and found that it was designed by Don Barber of New York. He had won a contest sponsored by the Beaux Arts Institute in Paris to design the best plan for a railway station for a large city. The terminal, completed in 1909, represents his winning entry, with some changes to the interior.
