This has proven to be a very sensible purchase. My Grandosn (aged 3) and I have had loads of fun with it since he got it as one of his a Xmas presents. It is now one of his favourite toys, and it is an extremely powerful piece of kit. Thomas can pull at least another dozen other engines/carriages, albeit he struggles to get grip when he is faced with hump backed bridge. He does eventually scrape and claw his way over, with all the others in tow, but I suggest a better tyre assembly would do the trick.
