My 3 year old son can't stop playing with this, having recently swapped allegiances from thomas the tank engine. The three characters are great, even though they are not the quality of the Bob the Builder characters you can buy. Lots of features - working ladder, flashing lights - 4/5 different noises/voices, seperate ladder with storage and working supports to stop the engine tipping over. Friction engine works well. Figures will actually sit in the cab. My only slight concern is the build quality - generally sturdy and strong, but I can see the doors/wing mirrors breaking off soon. (Maybe I'm being a little harsh!). Worth a purchase!!!!
