These are all the trains pictured in the first photo. I bought them a few years ago and played with them a lot. I don't remember exactly if they were a Daiso series, but I was able to run them on Daiso's gray rails. There are many scratches and small marks. Some of the yellow parts for operating them are missing. It seems that none of the trains work, even with batteries inserted. Even though there are three, some of them don't connect, perhaps because the combinations are different.
