I have completed refurbishment of this set and I realize how lucky I was to get a basic, under used set, with no battery damage or even use. The engine shells are like new. The only parts on the engines that are replacements are the port holes and one side ladder. Even all the hardware and screws are proper and original. The four cars and caboose are all original and also cleaned up remarkably well. I have a great 30 sec. video but am unable to load it for some reason. I apologize for that. Now my decision to keep it or sell it looms, while I have all the component boxes I do not have a set box.
