We bought this toy for our son's first birthday as he loves Thomas and Friends. From the moment he unwrapped the colourful box he was smitten with this. He loves his older cousin's metal take along Thoma trains so the lighter plastic versions of them with this set were perfect and he soon learnt how to place the trains on the track and push them down the mountain. The toy comes with 5 trains - Thomas, Percy, James, Diesel and Spencer plus a fun plastic boulder to chase them all. Although the track does split apart under a lot of pressure and the boulder is only designed to start from the second level not top, this has not hindered out son's (or our) enjoyment of the toy - he actually loves the fact he can take it apart and put it back together again! I would recommend buying this to anyone as it has a lot of longevity in it and creates hours of fun for little ones.
