This is a set of EF15 and D51 locomotives, along with a collection of Japanese freight cars. There are some scratches from use, but they are still in good condition. The D51 is missing its head, and some of the freight cars have peeling stickers and missing parts. Both run on size D batteries. To provide them in the best possible condition, I have cleaned the exteriors, cleaned and lubricated the power units, replaced the rubber tires with new ones, and removed the friction rubber, replacing it with new tubes. These are sold as-is, so please examine the photos carefully before considering a purchase. Would these be suitable for those looking for these items or for adding to their collection?
