Stacyjkowo Sezon 1 Odcinek 15: The Chugger Championship

The trainees are learning how to do different emergency stops with mud, leaves and water on the rails. Wilson is in heaven, as he likes nothing better than getting dirty! When they finish their lesson, Lori has a surprise for them: instead of being washed by hand, they're going to use the automatic Chugwash. Wilson tries to make his escape! / The trainees are heading for a lesson with Dunbar in the training yard when an underground tunnel catches Koko's eye. She wants to explore it but Vee says she isn't ready yet. Dunbar is called away and Koko decides she's going to see where that tunnel goes and persuades Wilson to come with her. They soon find themselves in trouble when they can't switch the tracks to turn around!
