“It's a what'll?"
"A Diseasel, I think. There's a notice about them in our shed."

"You had a cough in your smokebox yesterday. It's your fault the Diseasel came."
"It isn't!"
"It is!”
―Bill and Ben

The Diseasel is the twenty-first episode of the second series. It is based on the story of the same name from The Railway Series book, Main Line Engines.

Plot

Bill and Ben are tank engine twins who work at a china clay quarry. Their jobs are to take the china clay in trucks along the main line for engines and ships.

One day, Bill and Ben arrange some trucks and leave to pick up more, but return to find them gone. Their drivers find a patch of oil on the ground and realise a diesel is responsible for taking the trucks. Mishearing this as "diseasel", the twins remember a notice in their shed saying "coughs and sneezles spread diseasels", and they argue over who is responsible. Their drivers intervene and make a plan to get the trucks back which involves removing the twins nameplates and making them identical, as the diesel is skeptical about the twins.

The twins find the trucks in a yard, with a large green diesel at the front. Ben hides behind, with Bill going forward to demand the trucks back. The diesel claims the trucks are his and tries to shoo Bill away, but Bill reverses behind the trucks and Ben rides forward surprising the diesel (thinking it is the same engine). This continues for a while, causing the diesel to get dizzy. The twins then reveal themselves to him.

Edward arrives at the scene and asks what Bill and Ben are doing there. They claim that the diesel stole their trucks, but Edward scolds them for their rudeness. The twins apologise and the diesel forgives them. He introduces himself as BoCo and explains that he got his trucks mixed up with Bill and Ben's. Edward then sends the twins to take their lot back once they have picked up BoCo's trucks in exchange for theirs. After Bill and Ben leave, Edward tells BoCo that they do not mean any harm but can be maddening at times. BoCo laughs and replies that "maddening" is the word.

Trivia

  • In both the story from The Railway Series and the UK narration of the television series, Bill "pretended to be frightened" when he confronted BoCo. But in the US narration, Bill "pretended not to be frightened."
  • One barge has "Steve" written on it and a boat is labelled "Terrey". This could be a reference to crew members Stephen Asquith and Terence Permane.
  • This is the first and only time until Journey Beyond Sodor where an engine's basis is mentioned.
  • This is the first episode in where Bill and Ben are refered to by name.
  • The title is a portmanteau of the words disease and diesel.
  • BoCo's surprised face mask was only ever used in this episode.
  • The footage speeds up as Ben races through Wellsworth and as both twins do their trick.

Goofs

  • One of the twins' drivers says, "We'll take away your names and numbers," but the twins were not given numbers in the television series. This is likely due to the script for the episode being nearly identical word-for-word to the original story.
  • In the restored version, two hands can be seen pulling Bill and Ben backwards with string. Also, the end of the set can be seen in a still from the episode.
  • When Bill comes up next to BoCo, studio equipment is visible on the right.
  • When Bill and Ben annoy BoCo, he is missing his eyebrows.
  • When the narrator says "Bill took his place," the track where Ben was previously bounces up.
  • When Edward arrives, his bogie is derailed.
  • When the twins apologise to BoCo, Edward disappears, indicating that the footage from where Bill was accusing BoCo of being a bully was used at that point.
  • During the scene where the twins are puffing backwards and forwards to trick BoCo, they both have Bill's whistle sound despite usually having different whistles.
  • In the shot showing Bill and Ben's cabs, a camera shadow is visible on one of them.
  • In the final shot, Edward's whistle is bent.
  • Throughout the episode, the studio is reflected in BoCo's windows.
  • When Bill and Ben puff through the level crossing and Wellsworth Station, studio equipment is seen at the top of the screen.
  • During the twins' trick, BoCo always looks at Ben whenever he comes and just stares ahead whenever Bill comes.
  • In the close-ups of BoCo looking angry in the restored version, there is greenery behind him, rather than the yard.
  • In the UK version, when the narrator says "The twins were abashed," it shows Ben smiling, even though the word "abashed" means "embarrassed" or "ashamed".

Quotes

[Bill and Ben's drivers examine oil left at the scene of the crime]

Drivers: That's diesel.
Bill: It's a what'll?
Ben: A diseasel, I think. There's a notice about them in our shed.
Bill: Coughs and sneezles spread diseasels.
Ben: You had a cough in your smokebox yesterday. It's your fault that the Diseasel came.
Bill: It isn't!
Ben: It is!
Drivers: Stop arguing, you 2. Let's go and rescue our trucks.
Narrator: Bill and Ben were horrified!
Bill and Ben: But the Diseasel will magic us away like the trucks!
Drivers: He won't magic us. We'll more likely magic him!

'Drivers: [about the suspected diesel] Listen, he doesn't know you're twins. So we'll take away your names and numbers and then this is what we'll do.

BoCo: [looks up at Bill] Do you mind?
Bill: UK: Yes. I do. I want my trucks, please. / US: Yes, I do I want my cars back.
BoCo: These are mine. Go away!
Narrator: Bill pretended to be frightened.
Bill: You're a big bully! You'll be sorry!
Narrator: He ran back and hid behind the trucks on the other side. Ben now came forward.
Ben: Truck/Car-stealer!
Narrator: He ran away too. Bill took his place. (Bill and Ben proceed to taunt BoCo several times) This went on and on till the diesel's eyes nearly popped out.
BoCo: STOP! You're making me giddy. [Bill and Ben gaze at him] Are there two of you?
Ben: Yes, we're twins.
BoCo: I might have known it.

Edward: Bill and Ben, why are you playing here?
Bill: We're not playing.
Ben: We're rescuing our trucks/cars. Even you don't take our trucks/cars without asking, but this diseasel did.

Narrator: The twins were abashed.
Bill: We're sorry, mister...er...
BoCo: Never mind. Call me BoCo. I'm sorry I didn't understand about the trucks/cars.
Edward: That's all right then. Now off you go, Bill and Ben. Fetch BoCo's trucks/cars, then you can take this lot. There's no real harm in them.
Edward: But they're maddening at times.
BoCo: [chuckles] Maddening... is the word.
