We offered our son, 30 months. A real success, Romain the train has a function engine 'that allows it to move alone. As with all cars tut tut successful and very durable. Small flat, single Romain batteries, no batteries for the station when it is shown to be included would be missing an additional switch to allow the child to not have to do it alone. Many opportunities for different circuit (and suddenly possibility of saving space because it is big enough anyway lol) and other scenes of tut tut cars can be clipped together. We are delighted! Oh yes I almost forgot: other tut tut cars can run on the rails without problems! We now expect other motor vehicles because it is really fun ^^
