Dunbar, the shunting engine, instructs the trainees to master the many jobs required of engines in Chuggington. He is a teacher or mentor, and as Vee's right hand, ensures that chuggers are hooked up with the right rolling stock. He has a strong work ethic and takes great pride in the role he plays in shaping the young trainees to be successful, hard working engines. He works hard, and expects the young chuggers to do the same. When the trainees get frustrated that they aren't built for the job they are undertaking or get frustrated learning new things, Dunbar encourages them to keep on trying. His helpful advice and upbeat coaching keeps them going. His catch phrase is "Let's get those wheels to the rails!" All Chuggington StackTrack engines are compatible with Chuggington StackTrack playsets, creating the ultimate action-packed train play experience! With a wide assortment of collectible characters and exciting playsets, children can recreate favorite Chuggington episodes or new adventures.
