Gunnislake all the way. Why? Because it's three quite different things in one. From St Budeaux to Bere Alston it's a main line, with a couple of incredible engineering features. From Bere Alston to Calstock it's the archetypal West Country branch line, running high above a gorgeous green valley of lushness before taking a fantastic high viaduct to a picture postcard village with a tiny yet exquisite station. The last three miles to Gunnislake are like nothing else. More like some mineral railway twisting and turning its way up fierce gradients and reverse curves, taking 13 minutes and 3 miles to cover a distance about a third that as the crow flies. The hardest work you'll ever hear a DMU doing!
