"Road or rail, what do I care?"
— Jock, Jock the New Engine

  • Designer: Ivan Farrier
  • Builder: Arlesburgh Works
  • Built: 1976
  • Gauge: 15 inch
  • Configuration: 2-6-2

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


After Rex's steampipe 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. 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 suggested the name "Jock" for the new engine. The Small Controller and Jock liked the name so it stuck. Later, he pulled a doubleheader with Mike.


Jock was very cocky when he was first built, as a result of being rather strong, but soon learned the value of teamwork when Mike's injector failed and he had to pull Mike and his train single-handedly.


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


Jock is painted in a Highland Railway chartreuse yellow livery with red lining. He has a brass dome, red nameplates with yellow writing mounted each side of his boiler and "Arlesdale" written on his tender in yellow.


Railway Series

Jock also appeared in the book, James and The Fat Controller.


  • Jock was the last ERTL model to be made in the range. His tender is also shaped similar to how it was in the fifth illustration of "Jock."
  • Jock was mentioned in The Island of Sodor: Its People, History and Railways, but his first appearance was not until "Jock the New Engine."


  • ERTL (discontinued)
