One of Edward's Halloween stories makes Percy afraid to go to the "haunted" smelters that night, and Thomas teases him about it. Duck is angry and decides to work with Percy to make him think he's surrounded by ghosts.

Percy is very frightened when he passes an old mine at night and sees some buildings sink into the ground. He is even more scared when Donald and Douglas tell him about the "naughty gnomes".

None of the engines like to be in the middle of a train, so 'Arry and Bert enjoy putting steam engines in the middle. This causes trouble for Percy, but James is convinced that he can outsmart the diesels.

James thinks a red hot-air balloon is going to steal all of the railway's passengers.

After Gordon is very rude to him, Edward proves that he is still a useful, reliable and very helpful old engine.

Duncan's impatience on the incline lands him in big trouble.

Skarloey and Rheneas' old line is closed down. Seeing how unhappy they are working at the quarry, Rusty is determined to restore the line to its former glory.

When a branch knocks away Peter Sam's whistle, Duncan teases him, and boasts that any proper engine has a whistle. To prove his point, Duncan starts whistling loudly, but it comes loose while he is delivering an organ.
