Our son is an absolute Chuggington fan. This railroad is very stable, the supplied locomotives are worked beautifully. The roundhouse he loves especially because he can park the trains there and "sleep Send". The roundhouse is partially made of plastic, partially made of wood, but by and by quality. I do not think he would get somehow broken. The wooden rails are of good quality and I want to emphasize that they match with our Ikea rail line, which we can now interpret the entire nursery with tracks.
