"That would never suit His Grace!"
―Duke, Granpuff, fourth season

Duke, named after the Duke of Sodor and originally called The Duke, is a narrow gauge tank-tender engine, who is considered a hero amongst all the engines. He is also one of the oldest engines on Sodor.

Bio in the Railway Series

Duke was built at Boston Lodge in Minffordd, Wales to the order of John Arnold Norramby, Earl of Sodor and Chairman of the MSR, in 1879 for the opening of the Mid Sodor Railway in 1880. The Board of Directors named him in honour of the Earl and rostered him to haul the Opening Train. He worked with several other engines on the Mid Sodor, including Falcon and Stuart (later named Sir Handel and Peter Sam, respectively).

Soundly built, Duke was well maintained and kept in service until 1947 when the railway closed. While Stuart and Falcon were sold, no buyers were interested in him, so he was left oiled, greased and sheeted up in Arlesdale Sheds, where he was all but forgotten. He believed that the Earl would come to rescue him, but as time went on, he did not show, and Duke began to have doubts which grew stronger and stronger. He was unaware the Earl he knew had been killed during the Second World War, and that his successor was just a boy, who did not know of Duke.

He was later discovered by Mr. Fergus Duncan, the Reverend Teddy Boston and the Reverend W. Awdry in 1969 and taken by road and rail to Crovan's Gate. There Duke was restored and rebuilt, through the kindness and generosity of Sir Topham Hatt and the present Earl of Sodor, who shared the cost with Sir Handel Lloyd Brown. He was finally re-united with Sir Handel and Peter Sam and for the first time in its history the Skarloey Railway had motive power to spare. Over a period of weeks in 1982, Duke received another overhaul, which when completed allowed Sir Handel to be lent to the Talyllyn Railway while Sir Haydn was out of service.

He attended Ivo Hugh's naming ceremony in 1996.

Bio in the Television Series

Duke lived on the Mid Sodor Railway with several engines including Stuart, Falcon, and briefly Smudger, until the line went bankrupt and Stuart and Falcon were sold. Duke, however, was sheeted until a group of adventurers found his shed, buried under soil that had washed down from the mountains. Skarloey and Rheneas took him back to the Skarloey Railway, where he was soon returned to service.


Duke is one of the oldest and most experienced engines of the Skarloey Railway. He is also the mentor of Peter Sam and Sir Handel, from their younger days on the Mid Sodor Railway, when they were called Stuart and Falcon respectively. Although once lost for many years in an old shed that nature tucked away and forgot, after the Mid Sodor came to an end, he was found by rescuers, although quite by accident, when one dropped in through his shed roof. He may have a head teacher attitude and maintain his authority at all times, but can be quick to apply his knowledge and years of experience to help guide and correct any younger engine. He is proud of his name and keen to uphold the respect it merits. He can often be heard to say "That would never suit His Grace!" upon hearing or seeing something that he takes a disapproval to, or pedantically stating how he thinks someone would have adhered to the rules and regulations in his younger days. Despite their teasing ways, Sir Handel and Peter Sam have grown to become very fond of Duke and dearly nicknamed him "Granpuff" for his long service to the railway.


The story of Duke being rediscovered was based upon a true story about an engine abandoned in the Brazilian rainforest. Duke himself is based on Prince, a George England tank engine from the Ffestiniog Railway at Porthmadog, North Wales. Unlike his basis, Duke is built to 2ft 3in gauge, while Prince is built to 1ft 11½in gauge. Bertram is another member of this class.


In the Railway Series, Duke was painted red-brown with red lining. On the Mid Sodor Railway, Duke was numbered "1" and his tender bore the Mid Sodor Railway's crest and had no lining. When he moved to the Skarloey Railway, he was not repainted in the Railway's standard red livery, instead being restored to his brown MSR livery with brass nameplates. He bears neither his MSR number (1) or his SR number (8) for unknown reasons. In the television series, Duke was painted brown with yellow lining and has two red plaques on either side of his saddle tank with his name written in gold.

On the Reverend W. Awdry's model railway, he had "The Duke" written on his sides and "MS" written on his tender.

  • Duke's current grace is Richard Robert Norramby.
  • The Official Website and the 1986 annual states that Duke is the oldest of the narrow gauge engines. However, Skarloey and Rheneas are older, having been built in 1864 and 1865/6, respectively, while Duke was built in 1879. The mistake likely comes from Duke's basis being older than all three of them, having been built in 1863. The packaging for his Ertl model also incorrectly states he was built in 1863.
  • Duke's model and Smudger's face were used to create Bertram as a last minute resort due to financial difficulties, which is why Duke never appeared after the fourth season (excluding portraits and stock footage cameos).
  • The Reverend W. Awdry's model of "The Duke" was at the Reverend Teddy Boston's Cadeby Light Railway, before the railway finally closed in 2005.
  • Duke was the first narrow gauge engine on the Skarloey Railway to not be based on an engine from the Talyllyn Railway.
  • Duke's affectionate nickname of "Granpuff" that was given to him by Stuart and Falcon was the same affectionate nickname Wilbert Awdry was given by his grandchildren due to their observation of smoke coming from his pipe looking like that of a steam engine.
  • Duke was going to appear in the fifthteenth season episode, Kevin the Steamie, but his role never made it past the storyboard stage.


Sometimes they would wink at each other and chant solemnly. "Engines come and engines go, Granpuff 'goes on' forever!"
"You imprudent scallywags." Duke would say indignantly. "Whatever are young engines coming to nowadays?!"
"Never mind Granpuff, we're only young once."
"Well you better mind, unless you want to end up like No.2...."

- Stuart and Falcon teasing Duke, "Granpuff", "Duke the Lost Engine".

Duke was alone locked up in the shed.
"Where's His Grace?" he wondered. "Its not like him to forget me."
But his grace had been killed in the war. And the new Duke, a boy, hadn't heard of his little engine.
"Oh well," said Duke to himself. "I'll go to sleep. It will help to pass the time."
Years passed, winter torrents washed soils from the hills over the shed. Trees and bushes grew around. You wouldn't have known a shed was there, let alone a little engine asleep inside it.

- Duke alone locked up in his shed, "Granpuff", "Duke the Lost Engine".
