Jack

"This is a job for Jack! Don't worry Thomas!"

- Jack, King of the Railway

   Jack   Jack is a friendly and enthusiastic front loader.
 * Number: 11

Bio
When Jack first arrived on Sodor, he worked with the Pack to clear room for railway lines. Jack did well with Alfie - that is, until he tried to take some stone up a ledge but lost balance and tipped over. Jack learned his lesson, and redeemed himself by holding up a collapsing bridge until Thomas had passed over, at the cost of damaging his arms. Jack has since become part of the Pack.

He, along with the rest of the Pack, helped with the restoration of Great Waterton and worked with Alfie to construct a bandstand there. Jack also helped with the restoration of Ulfstead Castle and later saved Stephen and Thomas after the tracks they were on collapsed.

A magazine fact file states that he now works at the Sodor Slate Quarry.

Persona
Jack was like a toddler at first, who was still learning about the world and how to stay out of trouble. He is brave and will not take any hassle, as seen when he stood up to Max when the latter was bullying him and Alfie.

Basis
It is unclear what type of vehicle Jack is based on, but between the sixth and twelfth season he seemed to resemble a Nuffield tractor with an added front loader.

Since King of the Railway, Jack's basis has closely resembled an International 454 tractor. Because of this, his face shape has changed dramatically from round to rectangular.

Livery
Jack is painted red with the top half of his cab and his wheels painted cream. He has the number 11 painted in white on his sides. From King of the Railway onwards, the top half of his cab is painted grey, his back wheels are painted grey and his front wheels are painted red.

Trivia

 * In some promotional sketches of the Pack, Jack is seen with a backhoe arm and bucket. According to a SiF interview with Chris Lloyd, the arm was built, but was too problematic as it was hard to store all of the radio gear inside the model. An interview with Phil Fehrle gives a very different reason: "...if a story required Jack to be digging (using his back-hoe) and interacting with another character working at the same time, his face would be facing away from the action. For story purposes, it was important to feature the faces as much as possible; thus, the back-hoe was removed."
 * When Jack returned to full CGI he appears to have shrunk, as well as added hydraulics and a tall exhaust pipe.
 * Nathan Clarke did an audio sample for Jack on his DAA Management Page
 * A semi-complete face mask of Jack was preserved by fellow Thomas fans Christopher Blower and Owen Hayward.
