Inspector Emery Chuggington : Season 1 Episode 35

Chuggington is getting ready for an inspection, and it's also Emery's day off; he has trouble finding things to do, so he tries helping out, but causes more problems, causing Irving to spill his load of rubbish, Dunbar to constantly re-organize the rolling stock yard, and Eddie to spill paint. Emery hides on the elevated rail station, and finds a passenger waiting, and takes her on a tour of Chuggington. She later reveals she is the inspector, thanks Emery for his honesty and passes Chuggington with flying colours.
