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.

- This episode marks the final appearance of Sir Handel until the tenth season. It also marks the last appearance of Crovan's Gate until the eighteenth season (not counting stock footage in the seventh season).
- 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.
- This marks the first time Donald and Douglas appear and speak in the same episode since the second season.
- This episode marks The Diesel's only speaking role.
- The goods train next to James is being pushed by a crew member, as a shadow is seen.

- A pipe can be seen on the Diesel's air-intake in the close-up of the inspector's hat.
- Stepney is missing his crew in the first shot.
- When the Diesel breaks down, he has his air-intake covered, but when the inspector notices his hat, his air-intake cover is off.
- In the close-ups of Duck and Stepney during the scene where the Diesel breaks down, the scenery changes.
- In the shot of Duck and Stepney puffing up Gordon's Hill, a red and blue wire can be seen in the middle coach. In the same shot, the track in front of the engines appears to sink just before they roll over it.
- James has Smudger's whistle sound when he leaves the station.
- Gordon has Duck's whistle sound when he leaves Crovan's Gate.

- In a rare still image, Gordon has a crooked buffer.
