The two Baldwin steam locomotives that pull the Dollywood Express Train, Cinderella and Klondike Katie, were built in 1938 and 1943, respectively. The engines were built for the U.S. Army and used in Alaska during WWII to haul troops and lumber.
The Dollywood Express is great. It is a authentic steam locomotive that takes you on a five mile journey through the foot hills of the Smoky Mountains. It is a great ride if you want to get to see some of the park. Or get a look at construction that Dollywood is doing.
