Quality game with good materials. The company's reliability raises the level, it doesn't break at all! Kids enjoy it and it's fun. Easy assembly without many small objects, which makes it suitable even for young ages 1+. There are also other individual trains or wagons from the company that you can buy and fit on the tracks, making the game even more interesting. It runs on batteries and they last quite a while. However, I would like it to have sound, but that's a detail. One of the best trains for young ages.
