Cromford & High Peak Railway (Slide Show) 

A local-history enthusiast showed me the walk between Burbage on the outskirts of Buxton and the end of the C&HPR in Whaley Bridge. You can see a video of it here: goyt-valley.org.uk/project/errwood-high-peak-railway-walk/

For anyone interested in the C&HPR, there's a report of an 1880 journey along the entire route here: goyt-valley.org.uk/over-the-high-peak-railway/
