"You've been in the sun too long! Your dome has cracked!"
— Gordon

Thomas, Percy and the Dragon is the seventh episode of the third season. It first aired in the US on the Shining Time Station episode Scare Dares, in 1991 and re-aired in the Mr. Conductor's Thomas Tales episode, Missing Whistles in 1996.


Percy is still ribbing Thomas about the time he thought Percy was a ghost. Thomas pays no attention, knowing it was him all the time and, next morning, is asked to collect a special load from Knapford Harbour. Thomas is at first horrified to find it is a dragon, but his driver tells him it is made of paper and is needed for a carnival.

Meanwhile, Percy is stuck in a siding while shunting and has to stay there for the night because of jammed points while waiting for Henry to pass. His driver goes home for tea and Percy watches the other engines going back to Tidmouth. He is asleep until Thomas passes by with the dragon, causing Percy to get so terrified that he will not open his eyes until his driver comes.

The next day, Percy tries to tell Gordon, but Gordon thinks he is joking, which soon leads to the other engines teasing Percy about it. Later, he sees the dragon again, but is indignant when he sees Thomas pushing it. Thomas explains what happened and the two make up for their teasing.




  • In the restored version, in the last shot of Thomas and Percy in the shed, Thomas looks cross instead of asleep.
  • A deleted scene shows Gordon passing Percy in the siding.
  • Big Mickey and S.S. Vienna, from Thomas and Friends' sister show, TUGS, make their first appearances in the show as background characters. They continue to be background characters to this day, even making it into CGI.
  • A reference to the second season episode, Ghost Train is made.
  • This is based on the two Andrew Brenner magazine stories, Percy's Night Out and Percy and the Dragon.
  • The episode can be seen in a Japanese game, Magical Adventure.
  • When this episode first aired, the episode's title card was the only part of the opening credits left intact. This was done to make time for its pairing with Thomas Gets Bumped.


  • The dragon was said to be covered in lights, but it was actually lit up from underneath.
  • The steam vent goes off too early when Thomas blows steam at Percy.
  • In the shot of Henry, James and Duck, Henry's front wheels are derailed and his brake pipe is wonky.
  • The end of the set is visible behind Thomas in the shot where he goes under the bridge.
  • In the overhead shots of the jammed points, a truck next to Percy is derailed.
  • In the scene of Thomas and Percy in Tidmouth Sheds, Thomas is in a middle berth. But, the morning after, Thomas has moved to the berth on the far right.
  • The term guard is used in the U.S. version at one point.
  • Wires can be seen under the tarpaulin on the flatbed in front of the dragon when Thomas passes Percy. These are most likely wires connecting the power source to the dragon's lights.
  • In the first scene of Henry passing Percy, take a close look at the bottom right corner, Henry floats in mid-air.


  • James: "Look out, Percy! Or the dragon may gobble you up!"
  • Percy: "No one believes me! Maybe I did imagine the dragon after all."
