The Little Blue Tank Engine

When Thomas left to run his branch line, Sir Topham Hatt decided to borrow a little blue tank engine to shunt rolling stock in the Yard at Tidmouth. But, this tank engine proved to be badly behaved as he teased James about his bootlaces, so he was sent back to the Other Railway.

The little blue tank engine had a speaking role in James the Red Engine, but only made background appearances with no face.
