This was one of the last of the Victorian railways – it opened in 1899. It supplied milk to London and several quarries were opened along the track sending limestone to the industrial areas. The Trail was created after the railway closed in 1967. The signal box at Hartington Station has been preserved. You can go inside and see how it worked. At its southern end, the trail goes into a 600-metre long tunnel to emerge in the centre of Ashbourne.
