Tonton Streaming Chuggington (2008) S1E44 - Wilson & the Wild Wind

Dunbar has a new training device: a voice-operated storm simulator tunnel, which simulates wind, rain and fog. It's programmed to respond only to Dunbar's voice. Wilson particularly loves battling the wind. Dunbar says that in real conditions, it's best to couple up to another chugger as the added weight gives control.
