- “Hello Oliver! Are you being a 'Good-Gracious' engine? Beg pardon, of course, but we really don't like this sort of surprise.”
Oliver is still new to Sodor and tells Duck how very grateful he is that Douglas rescued him and Toad from being scrapped on the Other Railway. That night, Gordon, James and Henry praise Oliver. Unfortunately, Oliver, who has never been complimented by big engines before, soon becomes puffed up in the smokebox.
After pulling some coaches to Tidmouth, Oliver is told by the Fat Controller that he must learn how to handle trucks. Every wise engine knows that you cannot trust trucks. However, Oliver is so confident in himself that he ignores the other engines' warnings. Duck tries to convince Oliver of how trucks are troublesome, but Donald suggests that Oliver should learn for himself. After arranging some loaded trucks and then shunting empties to the hopper, he goes back to take the loaded trucks. But, the loaded trucks are comfortable where they are and don't want to move. They say that they do not want Oliver, preferring Duck, or one of the Scottish twins instead.
Oliver bosses the trucks about and takes them anyway. But the trucks decide to show Oliver who is boss by forcing him down the tracks. Oliver puts his weight against the trucks, but they still push him on, unaware of the danger ahead - he is heading towards the turntable currently in use by Duck. Then the inevitable happens - Oliver ends up bunker-first in the turntable well.
Duck, who now feels sorry for Oliver, is very concerned about the predicament, as now Donald and Douglas will have to work without the use of the turntable. That night, the breakdown train rescues Oliver. The Fat Controller kindly says that Oliver has a lot to learn about the troublesome nature of trucks, and Oliver agrees and The Fat Controller sends him to the works to be mended.
Once home from the works, Oliver is a much wiser engine and knows how to handle trucks.
