Climb aboard and meet them all. There is Spencer, the fastest express engine the Island has ever seen. Meet Emily, the sleek green engine with the beautiful brass dome; and new friend Arthur, whose spotless record gets ruined when Thomas plays a trick on him. Don't forget cheerful tractor Jack and all of his construction crew friends. And come meet the big and mighty Murdoch, who is always looking for some peace and quiet, but finds out what it means to have some Really Useful friends.
