Jock

Jock is the newest steam engine on the railway, and also the strongest. He was almost entirely built at the Arlesdale Railway's works. Having been first mentioned in The Island of Sodor: Its People, History and Railways, his first actual appearance was in the eponymous book Jock the New Engine - Rev. W Awdry had intended to include the character, but it was left to Christopher to write him in to the stories some years later.

Jock was very cocky when he was first built, but soon learned the value of teamwork and is now a Really Useful Engine. His name comes from the fact that he is painted in a yellow-green colour resembling the locomotives of the Highland Railway in Scotland. The name was suggested by Douglas, who remembered the Highland Railway from his youth.

Jock is based on the Ravenglass and Eskdale Railway's Northern Rock, which was built at Ravenglass in 1976.
