The World's Strongest Engine

"That's me, the world's strongest engine!"

- Diesel

The World's Strongest Engine is the eleventh episode of the sixth season.

Plot
Henry needs to go to the Works after being derailed, and unfortunately Diesel is the only engine available. The next day the trucks tease Diesel at the Docks, so he boasts he can pull twenty of them at once. Diesel soon finds he is unable to move them (unbeknownst to him, a shunter has put on the brakes) and pulls so hard he breaks loose and falls onto a barge. Diesel is sent home, while Henry pulls the trucks away.
