A set of an orange DD51 locomotive and three freight cars. The brown freight car is missing. There are three logs, but one is a different thickness. Plarail DD51, with a front switch. I think this is a rare type of product. It has been serviced and its operation has been confirmed on a straight rail. This type runs because the wheels are in contact with the motor unit's gear, so it will not run if the wheels are lifted. Please check the condition in the images. Thank you for viewing.
