Thank you for viewing. I like trains, but I'm not an expert, so I think this is probably the first generation 0 Series. It's a Japanese-made, tin toy train with a wind-up mechanism, consisting of a 3-car set. When you wind it up, it starts running, but due to the crude construction, the cars sometimes lift up and the movement is poor. The front car's left wheel is made smaller, so it rotates counter-clockwise. This item was collected quite a while ago, so there is considerable deterioration due to age. Please purchase only if you understand this.
