Thank you for viewing. This is the ECHO THE CLASSIC RAIL set. It includes 6 straight tracks, 12 curved tracks, and 4 overpass parts. The operation has been confirmed. Forward, backward, smoke from the chimney, and the lighting of the headlight have been confirmed. It runs on six size-D batteries. The light gimmick uses two size-AA batteries. I bought this new when I was a child, and after playing with it a few times, I stored it in the box. The main body and tracks are in good condition without any noticeable scratches. However, the outer box has some bends and peeling, so please understand this before purchasing.
