“We found him! We found our sleeping beauty!"
"Excuse me, are you a vandal? Driver told me vandals break in and smash things.”
―Duke and The visitors

Sleeping Beauty is the second episode of the fourth series. It is based on the story of the same name from The Railway Series book, Duke the Lost Engine.


After a hard day's work, the engines return to the shed and ask Thomas to continue the story of Duke. Thomas then reminds them of the story thus far.

While Duke was in his shed for many years, he was certainly not forgotten, and a group of adventurers approached the Fat Controller with a plan to find and rescue Duke. The team was prepared with maps and knew where to look, so the Fat Controller agreed. Everyone set off to the mountains in a train and began the long search. As the days passed, the search grew harder and there was no sign of Duke, but the rescuers were just as determined to find him.

The search soon finally ended, quite by accident, when one of the team members fell through the roof of Duke's shed, having not realised he was standing on it and age had weakened the roof to where it could collapse. Duke woke up and asked the men if they were vandals, but they assured him that they were there to rescue him and reunite him with Stuart and Falcon. After digging him out of the shed, they took Duke to his new home, the Skarloey Railway. Falcon and Stuart - now renamed Sir Handel and Peter Sam - were ready to greet their old friend, but they saw that he was asleep in the shed. They hushed each other, but it was too late as they had already disturbed him, so he complained that they woke him up and started to tell them about the older days.

The two engines laughed at this and told Duke that they were all due to go back to work the next day and they could keep Duke in order. Duke pretended to be cross, but he could not have been happier to be reunited with the engines.

Thomas concludes his story and all the engines agree on what a good story it was and how glad they are that it had a happy ending before they go to sleep.




  • Stock footage from Granpuff is used.
  • Duck is the only standard gauge engine from the previous episode not to appear at Tidmouth when Thomas is telling the story; James takes his place.
  • The Mandarin dub of this episode credits George Carlin as the narrator.
  • Many whistle sounds are missing in the American version and early UK version of this episode, such as Thomas' whistle at the beginning.
  • On Storytime with Thomas, this episode aired back-to-back with Duncan Gets Spooked.
  • This is the first episode to use a larger scale model for a Skarloey Railway engine.
  • This is the 80th episode of the franchise. 
  • This episode's title refers to the fairy tale of the same name about a princess who falls asleep for one hundred years due to a curse.
  • In the early UK version and the US version, in the scene when Stuart and Falcon left, their whistle sounds are omitted.
  • The three berth garage from TUGS is visible at the end.
  • This is the only fourth series episode to feature the short wheelbase plank trucks.
  • Skarloey's train was used to represent Bert's train from the original story and also he was used to represent an Arlesdale Railway engine despite not being introduced until they were in Sodor's Legend of the Lost Treasure.
  • When Stuart and Falcon go to meet Duke on The Skarloey Railway Falcon gains a new whistle only heard in Sleeping Beauty in the American version sound while Stuart has Smudger's whistle.


  • In the last scene of Falcon and Stuart, Stuart is tilted slightly.
  • In the British and international versions, Skarloey has Duke's whistle sound.
  • Despite being renamed, Sir Handel and Peter Sam still are referred to by their original names.
  • In the American versions, when Stuart and Falcon meet Duke on the Skarloey Railway, Stuart has Smudger's whistle sound.
  • When Skarloey starts his journey, he is facing forwards, but in every shot after that, he is facing backwards. However, it is likely for his face not to be shown on screen until Four Little Engines
  • The map of the Mid Sodor Railway is not even that of the Island of Sodor; it is actually a map of the Isle of Wight railway network, but upside-down. 


Percy: Thomas. Will you tell us the end of the story?
Thomas: You mean the one about "Duke the Lost Engine"?
Henry: Exactly.
James: But please remind us of the story so far.

Rescuers: [looking at maps in search of Duke] We want to find Duke and make him happy again. If we follow the old line shown here on the map. We'll travel north of the village and then into the mountains. And look. There's a sign for the old station. If Duke's anywhere, he's there.

[the rescuers unexpectedly find Duke in his buried shed]
Rescuers: We found him! We found our sleeping beauty!
Duke: Excuse me! Are you a vandal? Driver told me vandals break and smash things!
Rescuers: Bless you, no! We've dropped in because we couldn't find your door. Falcon and Stuart will be pleased to see you.
Duke: So they did remember!

[Stuart and Falcon prepare Duke a big welcoming return]
Stuart and Falcon: He's here! Shh! Shh!
Duke: You woke me up! In my young days engines were...
Stuart: Seen and not heard, Granpuff. We know!
Falcon: We'll all be back to work tomorrow. We're glad you've come back, we can keep you in order now.
Duke: Keep me in order?! Be off with you! [Stuart and Falcon leave] Impudent scallywags.

Thomas: And that, is the whole story. Did you like it?
Percy: Yes indeed.
James: Especially the happy ending.
Narrator: And soon, they were all asleep too.
