Chuggington is a special place where all the trains are known as chuggers. They talk, think for themselves and don't need drivers! Ride along with young trainees Koko, Wilson and Brewster as they embark on new adventures, make new discoveries and learn the true meaning of friendship. Brewster is excited about seeing the new Action Chugger movie, but Irving sends him to the foundry and Brewster worries he won't be back in time for the film unless he can be as speedy as his super chugger hero.
