- "You can't fool us!"
- ―Thomas to Percy
The Visitor is a magazine story.
Percy sees a new engine being unloaded from a boat, but the other engines do not believe him. They soon find out that the new engine is a visitor. The engine is to run an express line that has not been used in a while, but Gordon becomes angry at the fact that people think of him as really important. When the engine breaks down, Douglas takes his train while Donald helps him to the works. Gordon starts to tease him, but sees him upset and cheers him up.
