Thomas and the Whistle is a magazine story.
Gordon wants the small engines to whistle at him to show respect towards him, but when the small engines refuse to whistle at Gordon, he gets cross. He gets so cross that it makes the small engines whistle at him after all. Thomas however, does not mind whistling at Gordon. But when Thomas whistles at Gordon, his whistle becomes stiff and he cannot stop whistling until his driver finally makes him stop. That night in the sheds, Thomas' driver gives his whistle one last test and Thomas' whistle becomes stiff once again and it keeps the other engines up and makes Gordon cross. Thomas' driver heads to the workshop to fetch a workman to knock Thomas' whistle into place, but the workshop is closed. So Thomas has to wait until morning, in the shed, for his whistle to be fixed. Percy thought it was very funny. It took a long time for Thomas' whistle to grow quieter but at last a workman, who brought his tool bag, gave Thomas' whistle a hard knock and finally it had stopped. Gordon vowed that he never wanted to hear Thomas' whistle again. But Thomas smiled cheekily and gave Gordon a whistle.
- Thomas' whistle becoming jammed and then fixed by a workman hammering it in place in this story is similar to when Gordon's whistle became jammed in the first season episode, Whistles and Sneezes. This episode itself is based on The Railway Series story, Gordon's Whistle from Henry the Green Engine.
- Gordon wanting the small engines to whistle at him would later be used as a plot point in the ninth season episode, Respect for Gordon.
