Michael Portillo is in Crewe, a town steeped in railway history and immortalised in Victorian music hall, to investigate the making of the iconic cinema classic The Night Mail during the 1930s.

Following his Bradshaw’s Guide, Michael takes the train to Chester to discover the interwar origins of Britain’s most popular zoo. Michael learns how the work of Chester Zoo’s enlightened founder continues, and he helps to feed a young greater one-horned rhino.

Across the border in north Wales, Michael reaches the village of Gresford, the scene of one of Britain’s worst mining disasters, where 266 men lost their lives in 1934. Michael hears how it happened and how it is remembered in the community today. The Ifton Colliery Band plays Gresford - The Miners’ Hymn.

Over the River Dee, at Tata Steel in Shotton, Michael discovers a wartime boost to steel production on the site, where John Summers & Sons manufactured up to 50,000 Andersen shelters a week. The steel shelters and others designed by the company for people’s back gardens protected families from aerial bombardment by German planes. Show less
