The Engines of Sodor

It is a very wet season on Sodor, and Thomas hates the mud. Terence, on the other hand, doesn't mind it. But this may change after one very stormy day.

Gordon tells some engines at Knapford about the story of Diesel and what happened after Duck was sent away.

Diesel accidentally crashes some trucks into the Express coaches and then blames it on Henry. Henry tells Sir Topham Hatt to try to prove that he did with evidence, which ultimately leads to the engines discovering Diesel is not who they thought.

Duck and Douglas suffer an accident and are sent to be repaired. The Fat Controller brings Bill and Ben to help with the freight on the Little Western. Needless to say, though, the twins are very mischievous. Fortunately, Oliver has a clever plan to keep them in order.

The Fat Controller buys a special kind of engine called a Garratt, a three-headed-engine. Which can't agree with each other.

Duke remembers his siblings back on the Ffestiniog Railway, and how he did not get a long with them. However, the other engines can see that he really does miss them.
