Michael Portillo continues his journey from London to Edinburgh with the help of his 19th-century guide book. Following his trip from London to York on board the Flying Scotsman, Michael uses his Bradshaw's to trace the path of the famous service, beginning in the 'Key of the North' Newark-on-Trent and finishing in the cradle of the railways, Stockton-on-Tees. Michael rallies the choristers of a Tudor song school and admires the art of the railways before travelling to Retford, where he discovers a high-tech application for a Victorian rubber technology. A scandalous novel written in Thirsk leads Michael to a wildlife centre, where he is enlisted to feed a hungry young hedgehog named Charles.
