“I wish Thomas was here too.”

Thomas, Percy and the Dragon is the seventh episode of the third series. It is based on the magazine stories Percy's Night Out and Percy and the Dragon.


Percy is still ribbing Thomas about the time he thought Percy was a ghost. At first, Thomas pretends that he knew it was a trick the whole time. Percy jokes about him being afraid of the dark, but Thomas simply goes to sleep. The next morning, Thomas is asked by the Fat Controller to collect a special load from Brendam Harbour. Thomas wonders what it is, but the Fat Controller tells him to wait and see.

Meanwhile, Percy gets stuck in a siding while shunting at Lower Suddery and has to stay there for the night due to jammed points while waiting for Henry to pass with a goods train. His driver and fireman go home for tea, and Percy watches the other engines heading back to Tidmouth. Nighttime comes and Percy starts feeling very lonely in the siding, he gets scared when he hears a shrieking noise, not knowing it is only an owl, and wishes Thomas was with him.

When Thomas is waiting for his load at the harbour, he is horrified to find it is a dragon, but his driver tells him it is made of paper and is needed for a carnival. Workmen put lights on the dragon for Thomas to travel safely, and he sets off for the carnival. Percy is sleeping until Thomas passes by with the dragon, which terrifies Percy to the point that he refuses to open his eyes until his driver returns.

The next day, the points are mended and Percy tries to tell Gordon about what he had seen. Unfortunately, the big blue engine thinks Percy has been in the sun too long and puffs away with the express. This soon leads to the other engines teasing him about it. He begins to think he might have imagined the dragon, but later sees it again but is indignant when he sees Thomas pushing it. Thomas explains what happened and the two make up for their teasing.




  • Going by the Shining Time Station airings, this was the first third series story told by George Carlin alongside Percy's Ghostly Trick.
  • A deleted scene shows Gordon passing Percy in the siding.
  • This is the first episode to air on television in the US via Shining Time Station before airing in the UK. However, the first sixteen episodes of this series were released on home media at the time before airing a year later in 1992 for British audiences.
  • In the original UK dub, the music played when Percy waits for Henry to pass by, Percy at Knapford, and the other engines laughing is omitted. The music played when James teased Percy is omitted in both UK dubs and most international dubs, excluding the Ukrainian dub.
  • The owl's shrieking noise is heard twice in the UK and international dubs, excluding the US and Ukrainian dubs.
  • In the restored version, during the shot of Percy at the jammed points, his eye movement and steam coming out of him is different compared to the original version.
  • Big Mickey and S.S. Vienna, from Thomas & Friends' sister show, TUGS, make their first appearances in the show as background characters. Big Mickey continued to be a background character, even making it into CGI series, until he gained a face in the twenty-first series episode, New Crane on the Dock. S.S. Vienna would be repainted and named the S.S. Roxstar from the fourth series onwards.
  • A reference to the second series episode, Ghost Train is made.
  • The episode can be seen in a Japanese game, Magical Adventure.
  • When repeated on CITV on 19th February 1993, the end credits were entirely removed, save for the Britt Allcroft endboards. Steve Ryde provided voiceovers from this episode onwards.
  • This episode was released in Canada before Percy's Ghostly Trick meaning the Canadian audience would not know about the events.
  • The events of this episode were mentioned by Thomas in the twenty-third series episode, Wish You Were Here.
  • This episode was paired alongside Thomas Gets Bumped on an airing of Storytime with Thomas.
  • This episode marks the last and only of two things:


  • JEI TV version's Korean title of the episode is "토마스와 퍼시와 용" (Tomaseuwa Peosiwa Yong), however, this is incorrect grammar, and the correct title should have been 토마스와 퍼시 그리고 용 (Tomaseuwa Peosi Geuligo Yong).
  • In the restored version, in the last shot of Thomas and Percy in the shed, the narrator says Thomas went to sleep, but he looks cross. This is because the original shot of Thomas going back to sleep is replaced.
  • In the US version, Percy says to Thomas "I hope the guard leaves the light for tonight." The word "guard" is usually replaced with the word "conductor" in the US version, but in George Carlin's narration, it is kept as it was in the UK version.
  • Percy's eyes are pretty misaligned in many scenes throughout the episode.
  • 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.
  • When Percy puffs up to Gordon at Knapford Station, the coach behind Gordon is derailed.
  • In the shot of Henry, James and Duck, Henry's front wheels are derailed, and his brake pipe and tender misaligned. His eyes along with James and Duck's are also misaligned.
  • The end of the set is visible behind Thomas in the shot where he goes under the bridge and the track he was on ends behind him.
  • 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. The morning after, however, Thomas has moved to the berth on the far right.
  • 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 addition, when it becomes daylight, Thomas loses this flatbed.
  • When Henry puffs by Percy, a gap can be seen between his face plate, and eye.
  • When Percy's driver and fireman leave, Percy's face is crooked.
  • Before Thomas arrives with the dragon towards the end of the episode, Percy's cab, and coaches roofs are crooked.


  • Percy: Wake up, Thomas! Are you dreaming about the time you thought I was a ghost?
  • Thomas: Certainly not! Anyway, I was only pretending to be scared. I knew it was you, really.
  • Percy: I hope the guard leaves the light on for you tonight.
  • Thomas: Why? I quite like the dark.
  • Percy: Oh, really?! I am surprised. I always thought you were afraid of the dark. I wonder why.


  • Percy: You'll never guess what I saw last night.
  • Gordon: I'm a busy engine. I don't have time for your games.
  • Percy: I've seen a huge dragon. It was covered in lights!
  • Gordon: You've been in the sun too long! Your dome has cracked!


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