Visitors descend on Britain's steepest passenger railway, with a gradient of 1:1.8, to make the Deep Mine tour. They travel in a specially made 24-seat car, on a track with a gauge of 3ft (0.914m).


Boarding a train in a corner of the original slate slabbing mill of 1852, visitors now ride into an 1846 tunnel, hauled by battery-electric locomotive. Entering through the side of the mountain this journey into the early Victorian past remains on the level, and traverses some spectacular caverns.
