1. Derbyshire: Peak Express (2008)

Julia begins her exploration of Britain's lost rail empire in Derbyshire, the heart of the Peak District, with a walk along the popular Monsal Trail. Limestone cliffs and gorges abound, not to mention the tunnels and soaring viaducts of the Midland Railway - one of the most dramatic and unlikely main lines ever built.
