“What did they do?!"
"He turned him into a generator! He's still there behind our shed. He'll never move again.”
―Duke telling the story of Smudger to Stuart and Falcon

Granpuff is the first episode of the fourth series. It is based on the story of the same name from the Railway Series book Duke the Lost Engine.


On one cold wintery night on the Island of Sodor, the howling wind keeps the engines in the shed awake. Toby decides that what the engines need is to listen to a mysterious story, albeit with a happy ending. Thomas then tells the others a story his driver had told him recently:

In the story Thomas tells, there were three engines who lived on their own railway. Their engines were named Duke, Stuart and Falcon. Duke was the oldest of the three and had been named after the Duke of Sodor. Duke felt very proud of this and decided it was his responsibility to keep the younger engines in order. While other engines came and went, Duke outlasted all of them. Stuart and Falcon gave Duke the nickname "Granpuff" and were very fond of him, but did sometimes tire of hearing about His Grace and would occasionally tease him.

Duke soon warned Stuart and Falcon one day that if they did not behave, they would end up like Smudger; Duke told them that Smudger was a conceited and careless engine, who ran roughly and often derailed, spilling his loads. Duke tried to warn him, but Smudger simply did not care and laughed at Duke. However, he stopped laughing one day when the manager told him they were going to make him useful at last. From then on, the only running Smudger did was as a generator behind the shed. He was never able to move again.

Stuart and Falcon began behaving better and all three remained friends for many years. However, this all came to an end one day when their railway closed down. As a result, the engines were all put up for sale. Stuart and Falcon were bought, but no one wanted to buy an old engine like Duke. Stuart and Falcon promised Duke that they would find another railway for him to run on.

Duke's crew oiled and greased him one last time, put tarpaulins on him and bid him a final goodbye as they locked him in his shed and left to find new jobs. Duke went to sleep, waiting for the day he would be able to run again. As time went by, torrents of rain washed soil down from the mountains and trees and hedges grew over the shed. Nobody would know that a small shed was there, nor an engine asleep inside it.

Percy is disappointed and tells Thomas that his story does not have a happy ending. Thomas assures Percy that there is one, but it will have to wait for another night.




  • Duke's nickname "Granpuff" originated from Wilbert Awdry's nickname given to him by his grandchildren due to the smoke from his pipe looking like that of a steam engine.
  • This episode marks the first of a few things:
    • The first appearance of the narrow gauge engines in the TV series, from both the Skarloey Railway and the Mid Sodor Railway (in the form of Duke, Peter Sam (as Stuart), Sir Handel (as Falcon), Skarloey and Rheneas, respectively).
    • The first and only appearance of Smudger, who replaces No. 2's role from The Railway Series story. It also marks the first episode to introduce a television series exclusive character.
    • The first episode dubbed by Zoltán Csankó in Hugary, Bohuslav Kalva in Czech Republic and Guan Zhihong in Taiwan (as well as the first episode dubbed into Taiwanese Mandarin).
    • The first episode video edited by Kang Hyun-gi for JEI TV since second series episode, Thomas and the Missing Christmas Tree in South Korea.
    • The first appearance of Henry's depressed face since the second series.
    • The first and only mention of the other Mid Sodor Railway engines in the television series.
  • On early UK releases of Rock 'n' Roll and other Stories, the lines, "Their names were Duke, Stuart and Falcon," and "Whenever they did anything that Duke thought wrong, he would say 'That would never suit His Grace,'" are heard earlier.
  • In the original UK dub and US dub, when the narrator said "On their own little railway," the music is heard later.
  • Falcon and Stuart's nameplates were placed over the much larger "Sir Handel" and "Peter Sam" nameplates covered with black tape. This is because the post-Mid Sodor scenes were filmed first.
  • Most of the whistle sounds were omitted in the original UK dub and the US dub.
  • The Chinese Mandarin dub of this episode credits George Carlin as the narrator, and the Hindi dub credits Michael Angelis.
  • The cab roof from a scrap Thomas model can be seen.
  • A K'Nex stick can be seen poking out of the derelict Arlesdale Sheds.
  • The crawler tractor from TUGS is visible when Stuart and Falcon bash into each other.
  • In the original UK dub and US dub, the crash sound of Stuart and Falcon bashing into each other is different from the UK and international dubs.
  • This episodes marks the first on-screen use of a few faces, all of which were unused from the third series:
    • Thomas' unused third series depressed face, which would later be frequently used between the fifth and eleventh series, excluding Thomas and the Magic Railroad. It is also one of the only three times the face is used in the Britt Allcroft Company era.
    • Thomas' content face.
    • Toby's new angry face, not counting promotional material, and would be used occasionally until the end of the model era.
  • The Korean title of this episode has the same name as Duke.


  • As the narrator says "Other engines came and went...", Stuart is wearing his Peter Sam nameplate.
  • In the UK and international dubs, Skarloey and Falcon have Rheneas' whistle sound in some scenes, Rheneas has Skarloey's whistle sound, Duke has Falcon's whistle sound in some scenes and Falcon has Duke's whistle sound in some scenes.
  • Wires from the servos can be seen coming out from under Skarloey and going into the red coach.
  • When Duck says that the story must have a happy ending, a crack can be seen in his face mask next to his eye.
  • Duck's handrail is loose on the front of his smokebox.
  • Immediately after the narrator says "Duke was proud of this and loved to keep the little engines in order," Duke's eyes appear to shift further back into his face mask.
  • In the alternate shot of Stuart and Falcon bashing into each other, the props and mountain can be seen through their cabs.
  • In the shot of Smudger's second on-screen crash, the front truck shakes.
  • In a promotional image of Duke, Stuart and Falcon, Duke is seen wearing Falcon's cross face.
  • When the narrator says "Smudger stopped laughing then," his crew have black marker on them.
  • Duke's eyes are wonky in some scenes.
  • When Stuart and Falcon ask what happened to Smudger, their eyes are misaligned, and Stuart's eyes jitter for a brief second.
  • Thomas has some scratches on the side of his boiler.
  • In the close up of Henry, his face is tilted forward a bit.
