Millers Dale is a valley on the River Wye in Derbyshire.
Two railway viaducts cross the valley, the first built by the Midland Railway in 1866.
Increasing traffic meant that a second viaduct parallel to the first was built in 1905, increasing the number of tracks to four.
Millers Dale railway station was at the junction where passengers for Buxton joined or left the trains between London and Manchester.
The track bed is now part of the Monsal Trail.
