The Prologue

The prologue is the first release of Sodor's Fallen Engines

Plot
After lorries and buses take most of the work on the NWR, they have no choice but to finally become part of British Railways and admit defeat. BR takes no time in sending a diesel to the steam-run island.

Francis arrives on the Island of Sodor meeting the others at Vicarstown, much to the dismay of the others. The engines are not used to seeing a silent, boxy engine. Diesel is about to say hello, but refrains from doing so seeing the looks on the other engines faces. The Fat Controller tells Diesel to go with Edward to show him the ropes.

Francis and Edward go to the yards, which is in a terrible state. While Edward goes to the water tower, Francis organises all the trucks and coaches. Edward is shocked to see the yard so tidy and tells Francis he is a credit to the railway.

Francis and Edward head back to the sheds, where the other engines are talking. Duck is telling the engines what a threat Francis is to the railway, after his experience in Paddington. The other engines are refering to Francis as simply "Diesel". When Edward and "Diesel" get to the sheds, the other engines demand "Diesel" to sleep elsewhere.

The Prologue ends with a short summary of the events that will follow. Diesel never speaks a word on Sodor, Duck tricks Diesel into having an accident, which gets the Fat Controller fired, and how Diesel will never speak another word again.
