Duncan Gets Spooked

"Never mind him Peter Sam, He'll be frightened if he really saw a ghost."

- Rusty explaining Duncan to Peter Sam

Duncan Gets Spooked is the twenty-fourth episode of the fifth season.

Plot
After Rusty helps Peter Sam to the water tower with his train, Peter Sam's trucks break away and fall into a ravine. Sir Topham Hatt punishes Peter Sam by making him work in the yards until he can trust him again. Duncan chortles that Peter Sam's trucks will return to haunt him, so Rusty tells him of an engine who tried to cross the same ravine and fell into the swamp below. Duncan is dismissive, but Peter Sam's driver gets an idea. He and Duncan's crew plan to teach Duncan a lesson and take him across the bridge. After seeing the ghost heading towards him, (though it is just an engine formed by fireflies) Duncan is spooked and runs back to the safety of the shed.

Trivia

 * This is the first episode to use the new large scale models of the Skarloey Railway engines, although Duncan, Peter Sam, and Rusty's small scale models were used in the shed scene. However, in the fourth season, larger than normal models of the narrow gauge engines were used in close-ups of the human characters.
 * The ghost engine uses Skarloey's model and Percy's whistle sound.
 * The shed that Rusty, Peter Sam and Duncan were at was really the shed from Rheneas station from the previous season.
 * In Italy, the episode is titled "Trick for Duncan". In Japan, this episode is called "Events on the Night of the Full Moon". In Sweden, this episode is titled "It Spooks for Duncan". The Spanish title is "Duncan's Scare."
 * The engine formed by the fireflies resemble Rheneas and Smudger.
 * This episode most likely took place during the events of Rusty and the Boulder, as the quarry was seen in this episode. However, in the aforementioned episode, it's stated the quarry was brand new and was also closed in a short amount of time.

Goofs

 * When Skarloey passes by in the first scene, a red wire is visible underneath him.
 * In the UK narration, the narrator says that Rusty whistled goodbye, but Rusty is a Diesel, and does not have a whistle.
 * When Rusty leaves Peter Sam at the water tower, he makes puffing noises despite being a diesel.
 * Peter Sam's trucks come off the bridge coupled. When they fall into the ravine, they fall one by one uncoupled.
 * Duncan's face moves when he cries "Whoo-oo-oo!"
 * As the Ghost Engine falls off the bridge, he rotates during his descent. But in the shot of him landing in the swamp, he has stopped rotating, which would be physically impossible.
 * When the fireflies form the engine, the end of the tracks is visible.
 * Seven trucks are allowed up the incline in this episode. In Trucks!, only five were allowed.
 * Brakevans should have been added to Skarloey, Peter Sam, and Duncan's trains.
 * It's unlikely that fireflies would get into the shape of an engine.
 * For some reason, Michael Angelis is not credited with narrating this episode.
 * The term "railroad" is incorrectly used in the American narration, as Sodor is a British island.
