Going Slowly! is a magazine story.
Henry and James are trapped by a landslide. Terence arrives to help but he doesn't clear the blockage fast enough for James' liking. James tells Terence he'd be faster with proper wheels and not caterpillar tracks. Terence ignores them and soon both trains are on their way. Later, when the engines are going about their daily tasks, leaves start to fall from the trees. The engines are instructed to go slowly and their wheels only slip of the damp leaves. Terence's caterpillar tracks can grip on leaves easily. Now the engines are sorry for teasing Terence.
- In the final illustration, James gains a blue livery.
- A station named "Elsworth" is mentioned. Presumably they meant Wellsworth.
