Duke

Duke is a old engine

Bio
Duke lived on the Mid Sodor Railway with several engines including Stuart, Falcon, Bertram 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 the 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.

Personality
Duke is one of the oldest, wisest 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. Being the oldest engine on the line, Duke liked everything to be "just so". Although once lost for many years in an old shed that nature tucked away and forgotten about 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 headteacher 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 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 and deeply respect Duke and dearly nicknamed him "Granpuff" for his long service to the railway.
