Henry

Premise
Before the events of the Sodor Files series, Henry worked on the Main Line with his friends, particularly Gordon and James. Henry was a hard worker, and the task of pulling the famous "Flying Kipper" often fell upon him as well. After an initial bout of illness when first joining Sodor, he recovered and became one of the Main Line's most efficient workers.

Henry was never meant to come to Sodor. His design plans were stolen by a spy (later revealed in the series to be Old Bailey), who had a grudge against Sir Nigel Gresley and wanted to steal the plans of his new Atlantic class. Not knowing that the plans he stole were for an abandoned prototype concept, when the engine was built it was a major disappointment, which couldn't steam well. This later lead to problems for Henry's health. Old Bailey sold Henry for a ridiculous price to the Fat Controller, who eagerly accepted. When he realised it wasn't an Atlantic at all, but a scam, he was angry but kept Henry in his fleet out of pity and the fact that he needed another goods engine at the time.

Over the next years, Henry would get shut up in a tunnel for being selfish, prove himself despite illness, be rewarded with a new and improved shape which fixed his steaming problems, went on strike with the fellow "big engines", rescue two failed diesels, and helped replant trees when his beloved forest was destroyed by a storm. Henry emerged from these experiences as a more wise, if a little cynical, engine. Although he can be arrogant and overly pessimistic at times, he is strong and unfailing as a hard worker. He even gets to pull the express sometimes, much to Gordon's displeasure, an engine he has developed somewhat of a rivalry with.
