Never underestimate what a properly coached kid will do. My 3½ year old grandson loves operating my FlyerChief trains. I gave him his own little corner to play with as he sees fit. He loves RR crossings and populates them with Plasticville crossing gates and even blows the horn/whistle in the proper manner. He also has his own Brio set here and at his house which he loves. Every time he comes over, it's "Grandpa, let's do trains!". How can I resist???
