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. After that, he joined his Skarloey Railway engines forever and ever.


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 2 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.

Despite his "headmaster" attitude, Duke is gentle and kind to younger engines, but maintains his authority at all times. Duke was nicknamed "Granpuff" by Stuart/Peter Sam and Falcon/Sir Handel and the rest of the engines on Sodor except 999 narrow gauge engine because of his long serive to the Mid Sodor Railway, where he originally worked before being brought to the Narrow Gauge Railway. He sometimes tells the younger engines stories about Proteus, a legendary narrow gauge tank engine with a magic lamp hung upon his funnel, which according to legend, should someone find the lamp, their wishes will be granted.


The story of Duke was based upon a true story about an engine abandoned in the Brazilian rain forest. Duke himself is based on Prince, a tender engine from the Ffestiniog Railway at Porthmadog, North Wales.


Duke is painted brown with yellow lining and he has 2 red plaques on either side of his saddletank with his name written in gold. On the Mid-Sodor Railway, Duke was numbered one, and he had "The Duke" written on his sides and "MS" written on his tender.
