Hi Folks,
I started my boys off with a UP Flyer lionchief set when they were 3 and 1.5. Was a bit much for the younger one but he got the hang of it pretty quickly. Guys are 3 and 5 now and run with few problems now… need two independent loops or chaos happens quickly Like many have mentioned speed = fun so it requires intervention on the elevated sections above the concrete basement floor. They do love pushing the cars around the layout by hand (and still love the brio sets).
Amazing how quickly the kids pickup the running of the trains!
