Road Train is a magazine story.
The Horrid Lorries tease Thomas that he is on his "last trip" as they have special couplings attached to them that allow them to hook up with one another becoming what is known as a "road train". Things soon go wrong on the twisty roads when the lorries go too fast and come off the road and land in a field of hay. Thomas laughs it off and the Fat Controller scolds the lorries for causing trouble.
- The Horrid Lorries drives down Gordon's Hill before crashing, but there is not a road that goes over Gordon's Hill.
