Duke, named after the Duke of Sodor and originally The Duke, is considered a hero amongst the engines.
Duke is the oldest of the narrow gauge engines and the most experienced. He enjoys teaching others the proper way to do things. He often talks about the "Good old Days" when rules and regulations were obeyed. Despite his "head teacher" attitude, Duke is gentle and kind to younger engines, but maintains his authority at all times. 
Duke was built at Boston Lodge in Minfford, Wales in 1879 before being transported to Sodor for the opening of the Mid Sodor Railway in 1880.
In 1947, the line closed and Duke was sheeted and sheltered in Arlesdale Sheds. He was later discovered by Fergus Duncan, the Reverend Teddy Boston and the Reverend W. Awdry in 1969 and taken by road and rail to Crovan's Gate, where he was restored and returned to service in 1983.
Duke, when one first meets him, appears to be pedantic and strict and in a sense both are true about him. However, Duke was sheeted up in a shed for more than two decades, so Duke possibly did not know how things have changed.
Duke is wise from experience, and sees it as his duty to live up to his name's reputation.
BasisEditThe 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 tender engine from the Ffestiniog Railway at Porthmadog, North Wales.
- Duke was nicknamed Granpuff by Falcon and Stuart because of his long service to the railway.
- The official website states that Duke is the oldest of the narrow gauge engines. However, Skarloey and Rheneas are older.
- On the Reverend W. Awdry's model railway, he had "The Duke" written on his sides and "MS" written on his tender. In the Railway Series, Duke was painted dark brown with red lining. On the Mid-Sodor Railway, Duke was numbered one.
