Among the likes of Percy, Cranky and Bill and Ben, hero shots and bios of Timothy, Reg, Marion and Gator tell more on the new Sodor friends.
Two colouring pages with Gator, Reg and the team of Thomas, Percy and James are included.
This week saw details of the US DVD/Blu-ray bundle and Hit Entertainment's initiative for Tale's debut to the world.
Thanks to Adam Abrahart for the alert.
