The Thomas & Friends™ TrackMaster Cave Collapse brings the Thomas & Friends™: Digs & Discoveries™ episodes from Season 23 of the Thomas & Friends™ TV show to thrilling life! Thomas is ready to excavate, and teams up with his new friend, Darcy the digger to get the job done. Turn the crank to take Thomas up the mineshaft elevator. When he gets to the top, he drops down on top of Darcy! The motorized Thomas engine rides on top of Darcy, and powers the digger along. Darcy's rotating digging attachment knocks down boulders as the pair ride through a crumbling cave! The boulders are released when children turn the mineshaft crank. Thomas and Darcy make a dynamic, digging duo… and kids control the action!
