"Oh, I don't know. I like my brown paint."
"I've always been green. I wouldn't want to be any other color either."
"Well.. well anyway... blue is the only color for a really useful engine. Everyone knows that.
— Toby, Percy, and Thomas talking about their colors

Thomas, Percy and the Coal, retitled Double Trouble in American releases, is the first episode of the second season.


Thomas claims to have the best paintwork on Sodor and brags to Percy and Toby about it. When they tell him they like their paint, Thomas insults them by saying blue is the only proper colour for a really useful engine.

Later that day, Thomas is resting by the coal hopper when Percy arrives to fill up some trucks. Thomas decides to be cheeky, warning Percy of the trucks' antics and some unsafe buffers behind him. The trucks then push Percy into the buffers and the last truck passes the coal chute causing a pile of coal to bury Thomas and ruin his paintwork; Percy thinks this is very funny, much to Thomas's fury. It takes so long to clean Thomas that Toby has to take Annie and Clarabel instead and pull his next train.

That night at the sheds, Thomas is angry with Percy; he thought Percy caused his accident on purpose. Percy then becomes mad at Thomas for thinking so, whilst Toby thought it was a great joke. The two tank engines spend the rest of the night arguing.


''Now Percy has learned his lesson too!''

The next day, Thomas is feeling more cheerful as Percy brings in a train of trucks from the junction. The trucks are heavy and Percy wanted a drink, so he goes into the siding where the water tower is. As Percy heads to the siding, he finds he can't stop. He crashes through the buffers and lands in a pile of coal. Thomas had seen everything and leaves when his signal turns green.

That night, Percy and Thomas forgive each other and both vow to be more careful with coal.




  • This episode is based on the story of the same name from The Railway Series book, More About Thomas the Tank Engine.
  • This episode marks the first for a few things:
  • This episode replaced The Missing Coach after it was cancelled due to Britt Allcroft deciding the storyline of that episode would be too difficult for young viewers to understand.
  • When the narrator says, "It took so long to clean Thomas, that he wasn't in time for his next train," a first season-styled truck is seen.
  • In later versions of this episode, Christopher Awdry isn't listed in the credits.
  • The start of the Latin Spanish version features a brief clip of Thomas passing the Watermill from Percy's Promise.


  • Underneath the bridge Thomas crosses at the beginning, there is some black plastic.
  • When the narrator says that Thomas is resting in a siding, Thomas' eyes are wonky.
  • In Ringo's US version on the Thomas Breaks the Rules VHS, the A Cow on the Line Audio tape, and also in the Japanese version, the coal chute sound effects are absent.
  • In the panning shot of Thomas being cleaned, a shadow can be seen moving at the back of the shed behind Thomas, possibly that of a crew member. Thomas' eyes are also looking in different directions and his face is tilted.
  • When Toby backs up to Annie and Clarabel, his face is slightly loose and blu-tak is sticking out from the side of his face.
  • In the restored version, studio equipment is visible in the top corner when Toby pulls Annie and Clarabel.
  • In a deleted scene, a black plastic bag, which is used to simulate water, can be seen at the bottom while Thomas, Annie, and Clarabel pass the watermill.
  • Percy's eyes are wonky when he says that he has always been green.
  • When Toby takes Annie and Clarabel away, Clarabel's roof is not attached properly.
  • When Thomas and Percy are resting in the shed at the end, their eyes are wonky.
  • When Thomas is being covered in coal, the side shots show him clean but the close ups on his face show him very dirty.
  • When Percy arrives with his trucks at Tidmouth, a red express coach is amongst the trucks to the left of the screen, but after that there are only trucks on that siding.
  • In a close up of Thomas covered in coal at the coal hopper the hopper shakes.
  • In the restored version, studio equipment is visible at the top of the screen during a close up of the buffers and the water tower.


  • Percy: Hello, Thomas! You look splendid!
  • Thomas: Yes, indeed! Blue is the only proper color for an engine.
  • Toby: Oh, I don't know. I like my brown paint.
  • Percy: I've always been green. I wouldn't wanna be any other color, either.
  • Thomas: Well, well, anyway, blue is the only color for a really useful engine. Everyone knows that!
  • [he huffs away]
  • Narrator: Percy said no more. He just grinned at Toby.


  • Thomas: [watches the hopper load coal into Percy's trucks] Careful. Watch out with those silly trucks!
  • Trucks: Go on! Go on! Go on!
  • Thomas: And by the way, those buffers don't look very safe to me!
  • [Percy accidentally hits said buffers; the last load of coal pours down on Thomas]
  • Thomas: HELP!!! I'M CHOKING!! Get me out!
  • Narrator: Percy was worried, but he couldn't help laughing. Thomas' smart blue paint was covered in coal dust, from smoke-box to bunker.
  • Percy: Ha-ha! You don't look really useful now, Thomas. You look really disgraceful!
  • Thomas: I'm not disgraceful! You did that on purpose! GET ME OUT!!
