In this British animated children's program, we meet the locomotives Wilson, Koko and Brewster. They are three friends who learn to become working trains and in the meanwhile, they go on both adventure and have fun together. They learn valuable things like responsibility, courage and what friendship is. This DVD contains six episodes in which we get acquainted with Superloket, which is Chuggington's movie star and superhero. If there are any who like to play that they are Superlocked, its Brewster, Koko and Wilson.
