Some signs on the Island of Sodor are painted in a special green paint that glows in the dark. This helps the engines see the signs during the night. One day, Henry goes to the Steamworks to be repainted. Kevin, however, accidentally grabs some of the special glow-in-the-dark green paint and gives it to him. Henry is completely oblivious to the mix-up. When it gets dark, the paint activates. Thomas sees Henry's glowing paint and thinks it is a ghost train. He puffs into a siding, horrified and tries to warn Gordon. Gordon does not believe in ghost trains. James is the next to see Henry and also warns Gordon. Gordon thinks he knows how to deal with ghost trains, until he pulls up right next to Henry. He also believes it is a ghost train. At Tidmouth Sheds, James describes the ghost train to the other engines. A few minutes later, Gordon arrives and explains to Percy that he was not actually scared when he saw a ghost train. But it was not only the Steam Team who were frightened.
At Brendam Docks, Cranky, Porter and Salty also think Henry is a ghost, until Henry asks Cranky what is wrong. Upon seeing it is Henry, Cranky tells Porter and Salty who ask Henry why he was glowing and Cranky brings down a mirror to show him. Henry is surprised and realises he was given the wrong paint by mistake and he then realises that everyone thought he was a ghost train and laughs it off. When he comes back to the sheds from pulling the Flying Kipper, it is daytime and he was not glowing anymore. No one could sleep because they were too busy thinking about the ghost train that they saw. Henry tries to explain, but Gordon and James tease him, with Gordon reminding him about the time he was scared of the rain. This angers Henry, and he silences the other engines and tells them that he saw the ghost train and was not frightened at all. He then crossly backs into his berth and decides against explaining things, even when Emily kindly asks if he could.
That night, the engines are too scared to do their night trains. While Henry is away, the engines refuse to take the mail train. The Fat Controller is very cross. He tells the engines that there are no ghost trains. When Henry comes back, he gives everyone including the Fat Controller a fright. He tells the engines at last that it is just him, leaving Gordon and James annoyed. Thomas notices that the Fat Controller has disappeared. Suddenly, a figure with a bucket on its head emerges from the coal hopper. Everyone is horrified, even Henry himself. However, it was just the Fat Controller. He realises that Henry was given the wrong paint and tells him to get the right one first thing in the morning. As a bonus, the Fat Controller gives Henry a "glowing" report for being the only engine working during the night.
This episode contains examples of:
- Blatant Lies: Gordon explains to the Fat Controller that he doesn't want to go out because he has trouble with his boiler, and not because he's afraid of the ghost train.
- Call-Back: Much to Henry's annoyance, Gordon and James tease him for being afraid of the rain, which causes him to get back at them by claiming he was the only one not frightened by the ghost train.
- Cassandra Truth: When Henry tries to explain to the others that he was the "ghost engine", they won't listen.
- Death Glare: As Gordon and James laugh at Henry, the other engines are giving visible disapproving looks.
- "Everybody Laughs" Ending
- Face Palm: The Fat Controller does this after the engines tell him about the ghost train.
- Karmic Trickster: Henry uses his glow in the dark paint to scare the other engines as payback for teasing him earlier.
- Misplaced Retribution: Since they were all at the shed at the time, Henry ends up scaring not just Gordon and James, but the other engines who weren't teasing him, along with the Fat Controller. Granted they all seem to take it better than the former two.
- Not So Above It All: Even Edward succumbs to fear with the rest of the engines and refuses to go out at night to work.
- Visual Pun: The Fat Controller gives Henry a "glowing" report for being the only engine working during the night. Gordon audibly groans in response to this joke.
