Initially very excited by this train set, my one year old son there has just acceded to the locomotive and became one of his favorite toys. 2 large caveats though: - Lacks a referral in order to do all circuits and do not have to move one provided when the train made its tower (not handling for a child) - After 2 months of use only, the train stands still! Ends So interactivity and all the circuit's sake !!!
