Jack

Jack is a friendly and enthusiastic front loader. 
==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. 
==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.
