Build your Thomas & Friends world bigger and taller with the TrackMaster Sodor Spiral Expansion Pack from Fisher-Price! TrackMaster track has been redesigned to deliver an authentic Thomas & Friends experience with stronger connector plugs and a more realistic railway look. Your motorized TrackMaster engines will spiral towards adventure as they race up this steep incline and down the twisting corkscrew... or send them in the opposite direction! Connect this set to other TrackMaster expansion packs or playsets to create your own custom-made Island of Sodor! Includes track pieces, building risers, and two track adaptors, so you can connect the new TrackMaster track to the previous model (engines sold separately).
