The Thomas & Friends Take-n-Play Engine Maker lets you build your own engines in just a few easy steps! Just load three train parts into the hopper and load the chassis onto the platform. Pull the handle to raise the chassis up to the assembly line, then press the plunger three times, the engine advances down the assembly line as the hoppers drop parts onto the chassis! A final pull of the handle lowers the press and snaps all the parts firmly onto the chassis. You can even snap on extra accessories to customise your engine! The Thomas & Friends Take-n-Play Engine Maker includes two chassis (one with three wheels and one with two wheels), three engine body styles based on Thomas, Salty and Diesel with three pieces each, and four pairs of accessory pieces.
