Class25 locos were for many years the mainstay of the Oakamoor - St Helens sand services, usually double heading trains of HJV/HKV/HJO wagons.
Class 20s also saw use on sand trains - here a pair are seen heading an Oakamoor bound service at Podmore's mill south of Consall.
The last train along the Churnet Valley line operated by BritishRail ran on 6th February 1990 and conveyed condemned coaches for use in a military exercise at Oakamoor.
