Please confirm availability before purchasing. It appears to be made of metal. The wheels turn. The rails appear to be made of wood. The size is about 30 cm long and about 10 cm high. These measurements are approximate. Batteries are included, but I haven't tested it, so I don't know if it works. There are no instructions. I have displayed it inside my living room cabinet. As time has passed, it is not in perfect condition, but I will sell it to a collector if anyone is interested. I will ship it as is.
