Michael Portillo embarks on a scenic, thousand-mile rail journey from the Swedish capital, Stockholm, to Abisko in the northern reaches of the Arctic Circle. Steered by his 1936 edition of Bradshaw’s Continental Railway Guide, Michael boards a steam train to celebrate Midsummer in Marielund, learns to decorate a Dala horse in Mora and takes an icy dip in one of the country’s 96,000 lakes.
