Wow.., this is certainly one way to get hooked on the world’s smallest, operating, (1:220 scale), electric train. Incredibly and faithfully detailed, almost beyond belief. This set is comprised of a tank locomotive and two freight cars, along with 2 straight and 10 curved tracks, making an oval of 21” x 16”. The set is complete with a transformer. Train is about 6” long! Better hurry, we have only a few in stock!
