This is a set of two Sound Plarail trains: the E231 series Shonan color and the Sobu Line. There are some scratches from use, but they are still in good condition. They run on size D batteries, and the sound functions work perfectly. To ensure they are as clean as possible, I have cleaned the exterior and the power unit, and replaced the rubber tires with new ones, so you can use them immediately upon arrival. This is a sale of the items as they are, so please check the photos carefully before considering a purchase. Are you looking for these, or perhaps for adding to your collection?
