This is a set of items including a station building, station, and tunnels. There is some dirt. I have wiped them down with alcohol. Photo 2 uses 2 AA batteries and plays audio. Photo 4 is a manual platform door. Photo 8 uses 2 AAA batteries and the signal lights up. There is no audio. ★ I would like to include the rails in Photo 10 as a bonus in the gap in the cardboard box in Photo 9. There is some dirt. I will pack the items as carefully as possible, but I am not a professional packer. Please understand this before purchasing. Please also understand that I may reuse paper bags and cardboard boxes I have at home for packing. #Halloween on Mercari
