Listed as used but it looks new, been in a storage unit a while, so it’s a bit dusty, and the box is not perfect. The only issue I could see was on the tanker car. The plastic side valve top ring was broken off (See pics). Comes with a 120-volt controller, wiring, 2 little plastic railroad lanterns, the paperwork/ literature, and a couple of other items I have no idea what they are. The circular track is 51.18 round. Indoor/ outdoor, Has light and smoke. If you need more pics, message me. I own an antique shop, so lots of items come from my vendors and storage units, I also sell for other people.
