Rusty's Ghost Engine

Rusty's Ghost Engine
The ghost engine (his real name was never revealed) was a narrow gauge engine who used to work on the Skarloey Railway. According to Rusty, he was returning home one misty full moon when he lost control and fell into a ravine. His remains were never found, but workmen claim to have seen his ghost trying to cross the ravine, only to fall. Rusty told Duncan his story after he teased Peter Sam for allowing his trucks to derail in the ravine. Duncan disbelieved the story, but the next day Duncan's crew arranged things so that Duncan believed the engine was trying to cross the bridge at the same time as him, and quickly ran back.

The ghost engine uses Skarloey's model, and only appeared in the fifth season episode "Duncan Gets Spooked".

Edward's Ghost Engine
The other ghost engine was referenced in a story Edward told the others on Hallowe'en one year. Thomas later teased Percy, saying Percy thought it was real, but learnt his lesson after remaining behind at the Smelters to take a special load and thinking that some chains touching his cab were ghostly fingers.

The reason for the engine's death is not certain, but it can be assumed it was scrapped.
