KATO 822 Yo8000 N Gauge This is a N gauge model train from about 50 years ago. The case has some scratches, but there are no apparent damages to the main body itself. It runs smoothly on the rails. Total length: approximately 58mm I apologize that I do not have expert knowledge regarding model trains, and therefore I cannot answer questions about the operation or details. I understand that this is a precision model. I will wrap it in cushioning material and ship it carefully. Please understand that this is a used item, and refrain from purchasing if you are sensitive to such things.
