Join Julia Bradbury on a new outdoor adventure as she visits historic railways lines across England, Scotland and Wales. Follow the old tracks and explore the overgrown cuttings and ancient viaducts of Britain's lost rail empire. Through stunning landscapes and urban backstreets, each constrasting journey has a unique story to tell and offers insight into industrial Britain.

Begin your journey in the picturesque Peak District, exploring the limestone cliffs, tunnels and soaring viaducts of the Midland Railway - one of the most dramatic and unlikely main lines ever built. From the least-visited parts of Snowdonia to the pioneering tramways and crumbling engine houses of Cornwall, discover how the rise and fall of the railways has altered lives and localities across the UK. How did the arrival of the railway lines change the unruly territory of Scottish clans and Rob Roy? Is the railway responsible for Speyside's world famous whisky industry?
