The Colourful Engine is a magazine story.
Skarloey and Rheneas love the variety of colours they can see in the beautiful landscape during Summer. But one day, the fog blocks the scenery. Peter Sam is taking paint to the stations, but he breaks down and, when Skarloey bumps into his trucks, he gets covered in paint. Skarloey helps Peter Sam back to the Yard, but Rheneas teases him for being a "colourful engine".
- Peter Sam is depicted with his old funnel.
- In the last illustration, the truck that Skarloey is pushing is standard gauge and does not have buffers.
- The front cover of the magazine featuring this story shows Thomas and Skarloey together, but Thomas isn't seen or mentioned in this story.
