Thank you very much for viewing this product! This is a KATO E231 series 500 series Yamanote Line N gauge model train, a basic 4-car set. I purchased this several years ago and ran it a few times. After that, it was stored at home, so I think the condition is fine. I have confirmed that it runs. *Please check the condition in the photos before considering purchasing.
