Tennessee Valley Railroad Museum by MatthewMetcalfe
The Tennessee Valley Railroad Museum presents a look into railroad history. In addition to the trains that are exhibited in their yard, there are displays in the Station. The most unique thing though is that you can take a train ride through the area in a pullman car. Railroads were a critical part of Chattanooga's history and this museum shows a lot of that history with real trains and not just photos.Occassionally they offer a day out with Thomas which is great for the children (although a little crowded for the adults!) There are also leaf watching tours that I think would be a great fall getaway.
If you like trains and their history, then this is a place you must see when in Chattanooga.
