The Deputation is the seventeenth episode ever made in Season 2.
Heavier than normal, snow has fallen on the Island of Sodor and while the other engines hate it, Donald and Douglas are used to the conditions and clear the lines. They encounter one drift deeper than most, which turns out to be Henry.
Henry is rescued and returns to the shed, but both Donald and Douglas are upset. They know the Fat Controller will be returning soon and, after destroying a signalbox and the spiteful brakevan between them, are worried that he will send one or possibly both of them away which would lead to them being scrapped. The other engines decide they have to do something to allow both Donald and Douglas to stay. However, no one knows what to do.
Percy talks to Edward about the situation and he suggests that the engines nominate someone to talk to the Fat Controller, a "deputation" and they agree to this and nominate a horrified Percy to do the job.
The Fat Controller returns and a nervous Percy stammers through his speech about allowing the twins to stay. The Fat Controller catches on that Percy is a deputation and tells him he understands.
Later in the sheds, the Fat Controller responds to the engines' request. After informing them, although he understands their feelings, he doesn't appreciate them interfereing in his decision making. He then surprises everyone by awarding Donald and Douglas, as a result of their good work in the snow, with new coats of paint and their names painted on them and warns them that he doesn't want to see any more mistakes. The engines realise that the Fat Controller is allowing both twins to stay and, overjoyed, drown out the rest of his speech with happy whistles.
- When Donald and Douglas leave the yard back-to-back, a truck is being derailed.
