Manchester, Buxton, Matlock and Midland Junction Railway

The Manchester, Buxton, Matlock and Midland Junction Railway ran from a junction with the Midland Railway at Ambergate to Rowsley north of Matlock and thence to Buxton.

In time it would become part of the Midland Railway's main line between London and Manchester, but it was initially planned as a route from Manchester to the East of England, via the proposed Ambergate, Nottingham, Boston and Eastern Junction Railway which would meet it a little further north along the North Midland line at Ambergate. The act of Parliament, Manchester, Buxton, Matlock and Midlands Junction Railway Act 1846, for a line from just south of Stockport to Ambergate was passed in 1846.

Currently, the section north of Millers Dale is open as the Great Rocks freight line, Derby to Matlock still holds passenger services as the Derwent Valley line, Matlock to Rowsley is the Peak Rail heritage line, and Rowsley to Buxton has become the Monsal Trail for cycling, horse riding and walking.
