Stepney's visit is coming to an end and Thomas, Percy and the rest are very sorry that he is leaving. But they have other things to worry about when a big-headed Diesel comes to help in the yard and scoffs that steam engines are old fashioned. However, when a bowler hat causes delay, Duck and Stepney show him just what a steam engine can really do!
