Jock

Jock, named by Douglas for his yellow livery, is the fourth steam engine on the Arlesdale Railway, and the strongest.

Biography
After Rex's steam pipe began leaking one day and Frank had to take his train, the Small Controller began thinking they needed another engine, and so he arranged for Jock to be built. He was designed by the Arlesdale Railway's own Chief Engineer, Ivan Farrier, working with Ian Smith of the Ravenglass and Eskdale Railway, who also needed a fourth steam engine. It is not surprising therefore that Jock and the R&E's "Northern Rock" should show marked similarities.

Jock's design incorporates all the best features of Bert, Mike and Rex. As in the case of Bert, the tall chimney and cab give Jock a true narrow gauge appearance. Except for the boiler, firebox and cylinders, which were fabricated at Crovan's Gate Works, Jock was built entirely at Arlesburgh Works. The Fat Controller played a role in arranging Jock's construction, a project which was dear to his father's heart.

When Jock first came out for testing, he was still unnamed. Jock's paint colour reminded Douglas of his days on the Highland Railway, and he suggested the name "Jock" for the new engine. The Small Controller and Jock liked the name, so it stuck.

Later on, Jock pulled a doubleheader with Mike, who had come to resent Jock's popularity and resulting arrogance, and tried to teach him a lesson by cutting off steam, forcing Jock to do all the work. The prank backfired when Mike broke down on the homeward journey, and Jock had to pull both him and the train. That evening, the two engines made up their quarrel, and Jock resolved to be less conceited in the future.

Personality
Jock was very cocky when he was first built, as a result of being stronger and more popular than the other engines, but soon learned the value of teamwork when Mike's injector failed and he had to pull Mike and his train single-handedly. Afterwards he became more helpful and kind towards the engines.

Basis
Jock is based on Northern Rock, an engine who works on the Ravenglass and Eskdale Railway. Nothern Rock was built at Ravenglass in 1976. Two other engines based on Northern Rock's design have been built at Ravenglass for the Shuzenji Romney Railway in Japan.

Livery
Jock is painted in the Highland Railway's livery of chartreuse yellow with red lining. He has a brass dome and a brass builder's plate on the sides of his cab. He has a red nameplate with a gold border on the sides of his boiler with his name (Jock) on them, also in gold. His railway's name (Arlesdale) is painted on the sides of his tender in yellow with a red border. He has red buffer beams with silver buffers.

Trivia

 * Jock was the last Ertl toy to be made in the range. His tender is also based on the illustration where his tender erroneously has a dip at the back.
 * Jock was mentioned in The Island of Sodor: Its People, History and Railways, but his first appearance was not until three years later in the The Railway Series book; Jock the New Engine.
 * Unlike Northern Rock, Jock has round buffers and a tender with six wheels instead of eight wheels, though these could be illustration errors.
 * In the Korean version of Jock the New Engine/Wilbert the Forest Engine, Jock's name is "작"(Jak).
 * Just like Mark VI, Frank, Fred, and Ivo Hugh, he was built on Sodor. Cleo from Thomas & Friends was also built on the island.
 * He is the only Arlesdale engine, as well as the only Railway Series exclusive character, to be illustrated by Ken Stott.
