An engine shortage has arisen and the only engine available is a Diesel, who insults the engines almost immediately after arriving. The engines are furious, but cannot think of a plan for revenge. There is no need though, as the Diesel sucks an inspector's bowler hat through an air-intake vent just after starting. Duck and Stepney take his train, and reach Crovan's Gate in record time. Stepney leaves the next day and, while the engines bid him farewell, the Diesel creeps sulkily away, leaving only two things to remember him by, a bad smell and a battered bowler hat.

- In a rare picture, Gordon is in Henry's place when the Fat Controller makes the announcement.
- According to the description on Thomas and the Special Letter and other stories, The Diesel was brought to Sodor to take over Daisy's work while she was ill, but Daisy is not seen nor mentioned in this episode.

- Gordon has Duck's whistle sound when he leaves Crovan's Gate.
