I have bought the starter after we visited a model railway exhibition for our 4 1/2-year son. When track structure we had to help a little. But what I felt for very great. It will play again and the common child is just great. The tracks and the train are made of plastic. Power but very robust. The locomotive with the sounds and light is easy to play great times in the Dark. Our son is not getting enough from the web. Here creativity while playing no limit is set.
