Traintastic action is just a tap away with the T.A.G. (Touch And Go) touch-activated Chuggers! You are the train conductor! When you tap on their roof, these 3.75-inch scale trains start their engines and are wheels to the rails until you give them another tap to bring them to a stop. Each T.A.G. train is compatible with all Chuggington track sets, as well as most other train track systems! T.A.G. Wilson is an incredibly enthusiastic multi-function engine who's filled with bucket loads of confidence! Alongside his fellow trainees Koko and Brewster, Wilson's ready to put his wheels to the rails to solve problems all throughout the world of Chuggington! T.A.G. Chuggers are designed for kids ages 3 and up. Each train requires 2x AAA batteries, not included.
