The Settle & Carlisle Railway soars across the Pennines on lofty viaducts with a mystique unrivalled by any other railway. Steam locomotives from the mighty Mallard and the world famous Flying Scotsman, Duchess of Hamilton and Evening Star to the humble Black 5s still thunder through the mountains and tunnels, over Ribblehead, through Kirkby Stephen and Langwathby, from Settle to Carlisle and back.
