Smudger

Smudger is a television-series-only character that replaces Stanley, who was in the books.

Backstory
Smudger was an American engine. He rode rough and often came off the rails. He was very cocky too. He said "In the States we don't worry about a few spills."

One day, his driver and fireman had enough. They decided to turn Smudger into a generator, and he was put behind the sheds. His wheels were removed, and he never moved again.
