Works confirmed. This is a very old toy. The acquisition date is unknown, but there is a 2005 marking on the back. It's designed to move even without rails. The series is unknown, but it seems to move sideways, like it would say "I'm Thomas" and "Oh, there are no tracks!" and go straight. It is currently running with the batteries inside, so I will ship it with the batteries still in. It was played with by a child and has been stored at home for a long time, so there are scratches, color fading, non-removable stains, and deterioration of the rubber parts in various places. Please check the images. If you are concerned, please consider carefully. I will sell it as is. I have described the transaction in my self-introduction, so please bid if you understand. The color of the item may look different from the actual product due to the shooting environment. Please understand. I have various other items for sale, so please take a look if you have time. #ThomasTheTankEngine #Thomas
