The Lego / Duplo toys are usually safe bets, that's why when my son 27 months began to take an interest in trains is to this case that I turned. Nothing to say, here is the ABC of the electric train. Enough rails for proper oval, a locomotive, a car, three characters ... In short, what fun for a while. Interestingly, the train stops itself when it encounters an obstacle or if the wheels are not in contact with the ground. Here is an excellent initiative to prevent unwanted changes of batteries. My son adores, vary, sometimes thrown into the air but so far the object has passed all fastness tests he had to undergo. A good investment to interest your children railway.
