Spotted a pile of these in the Hemel Hempstead branch.My son was a massive Thomas fan before I built his Hornby layout, and has a big collection of these which used to cost and still do about £10-£12 each, so this is a great price, especially for what I think is a new engine addition.
This works with the previous Tomy Blue Road & Rail Thomas track, and new Trackmaster sets/track.
There is a lever switch on the top of the cab, which switches motor on or off, in off mode they can be pushed along (or as my son used to say Puffed along!).For motorised use it'll need 1 x AA battery.
Forgot to add, in the box you also get 2 trucks/carriages like the picture.
*update 21st Nov* Just come from the Bletchley store, still plenty of stock, and various name engines available
