The blades are made of - and fold, the lok speaks a few words in German and to interact with the other locomotives from Chuggington Interactive range from the works without problems. The locomotive looks robust, contrary to some previous speakers, I can not complain about the wings, which is locomotive ever fallen down but keep the wings. appears to be quite robust for me and brings a lot of fun, we can see the locomotive as well as the Chuggington Interactive series only recommend.
