The Fat Controller invites Stepney to work with Toby and Mavis at the quarry. He impresses everyone so much that the foreman asks Stepney's driver to take a night special. He agrees, forgetting to ask for the Fat Controller's permission. Stepney gets lost on the way home, eventually arriving at the Smelter's Yard.

Based on the magazine story "A Fishy Smell."

Henry is cross when Thomas delays him, and refuses to listen to his warning about a line eroded by high tides. The signalman isn't warned in time, and Henry is sent right down it.
