Preschool conductors can direct their favorite Thomas & Friends adventures with a Greatest Moments Motorized Engine. Flip the switch on the top of the toy train to set the stories into motion. Engines are compatible with all Thomas & Friends tracks except wood. Connect to other engines and add additional Thomas & Friends vehicles, cargo cars and tenders using the plastic connectors. (Additional engines and cars sold separately.) Featuring classic designs of favorite characters, these were made for preschoolers and Thomas & Friends fans.
