Michael Portillo fast tracks to the early 20th century to embark on a new series of railway journeys through Edwardian Britain. His ‘new’ guide book, published over a hundred years ago, unlocks Britain’s railways at their zenith, when some 20,000 miles of track reached into every corner of the country. Michael navigates a vibrant and optimistic Britain, at the height of its power and influence in the world, but a nation wrestling with political, social and industrial unrest at home.

Part 15: Criccieth to Caernarfon
With his Edwardian Bradshaw’s railway guide tucked under his arm, Michael Portillo begins the last leg of his journey from Hull to Caernarfon. In picturesque Snowdonia, he braves the fastest zip line in the world – stretching 1,500 feet across a vast slate quarry. He uncovers a bitter industrial dispute between quarrymen and the owner of the pit, Lord Penrhyn, which divided the community at the beginning of the 20th century.

Riding north Wales’s splendid heritage railways, Michael visits the home of British mountaineering, Pen y Gwryd, to hear how an Edwardian journalist and poet created a climbing community, which grew to include men who would conquer Everest in the 1950s. Michael meets the grandson of one of his political heroes, the Edwardian Prime Minister David Lloyd George, at his birthplace in Criccieth. At the impressive 13th-century fortress of Caernarfon, built by English King Edward I, Michael discovers the early 20th-century history behind the ceremony now traditional at the royal investiture of a Prince of Wales.
