I bought this for a 2.5 year old to join his Thomas train. Although he tends to be quite rough with it (he has finally stopped throwing toys), it stands up to the treatment well. The connections between the other parts are well constructed too. We just have to teach my grandson to swich off the train when playing with another toy so the batteries last longer!
This is a great value train with two trailers, and a fine addition to my grandson's Track Master set which he has endless fun with. I can highly recommend the Thomas Track Master trains to everyone.
