KATO 3021-4 EF81 Cassiopeia The main body is very clean. It appears to be unused. ◇◇◇ I am sorry, but I do not have expert knowledge regarding model trains, so I cannot answer questions about the operation or details. I understand that this is a precision model. When shipping, I will wrap it in cushioning material and send it with care. I am also listing other N gauge items. Thank you very much. ◇◇◇
