- “Blow, Percy!”
- ―Percy's driver
Percy Saves the Day is a magazine story.
One night, Diesel is being particularly restless. He remarks that all steam engines are useless, especially Percy as he is so small. Percy is upset and Diesel asks him to name one thing that he can do better than a diesel engine, but Percy cannot. The following day, Diesel sets off with an urgent load whilst Percy is left in the yard shunting some troublesome trucks. Then, the Fat Controller runs over. He explains that the viaduct has been leaking and the tunnel below has become iced up. He needs a compact engine to go inside and thaw it out before Diesel can get through. When he arrives at the tunnel, Diesel has been put into a siding and is muttering angrily under his breath. Percy puffs inside and the fireman puts loads of coal into his firebox and Percy wheeses out lots of steam. Soon, enough of the ice has melted for Diesel to squeeze through. Diesel quickly (and quietly) thanks Percy, who is very proud to be a compact steam engine!
