Julia Bradbury has her backpack on to explore the great outdoors. Julia's walks follow the old tracks, overgrown cuttings and ancient viaducts of Britain's lost rail empire, visiting disused lines across England, Scotland and Wales. Through stunning landscapes and urban backstreets, each contrasting walk has a unique story to tell, offering Julia a window into industrial Britain and how the rise and fall of the railways has altered lives and localities across the country.
