“You don't know the rules!”
―Fergus to Diesel

Fergus Breaks the Rules, retitled Thomas and the Search for Fergus in some American releases, is the eighteenth episode of seventh season.



"I wanna go back to the cement works. None of the other engines like coming here, it's so scary!"

The Fat Controller has brought Diesel to help out at the Cement Works for a while. However, Diesel becomes annoyed with Fergus. Later on, Diesel lies to Fergus about the Fat Controller sending him to work at the scrapyards. When Fergus arrives, 'Arry and Bert frighten the traction engine and he runs away. The Fat Controller receives a call that Fergus is missing. So, he sends Thomas to search for him. He finds Fergus hiding in a siding and takes him to the smelters yards where the Fat Controller is waiting. In the end, Fergus happily goes back to work at the Cement Works, and Diesel is transferred to the smelters yards as punishment.
