This photo was taken on 28/05/2017 but explains the area south of Harpur Hill so well I have included it in the August 2016 set. The view is northwards with Harpur Hill village in the valley to the right. Bottom middle to top middle is the original 1830 C&HPR alignment, this heads around the flat-topped hill to the present Harpur Hill industrial area. Just about where the course disappears from view was Harpur Hill Jn.
Curving from top middle to the right middle is the alignment of the 1892 line from Harpur Hill Jn on the original C&HPR down at 1 in 41 towards Hindlow on the Buxton - Dowlow line. The section of the C&HPR in the foreground closed in 1892 but was reinstated in 1929 to serve Hillhead Quarry. The Hillhead Quarry line, via reversal at Harpur Hill Jn to Hindlow finally closed in 1973.
