The Pack is a group of construction machines used for various jobs around the Island of Sodor. Jenny Packard is their controller.
Jack is a red front loader who joined in 2002. He was very hyper when he first arrived and eager to jump in. However, this lead to an accident when he fell over whilst carrying rocks that were too heavy for him. But Jack redeemed himself when he saved Thomas after a bridge collapsed.
Jack has no real basis. However, the Thomas the Tank Engine Wiki claims he is similar to a International 454 tractor after his physical appearance was changed for King of the Railway.
