Leadhills Station, on the Leadhills & Wanlockhead Railway in South Lanarkshire. Britain's highest adhesion railway reaches a height of 1,500ft at its Wanlockhead end. A railway was built here in 1900 and this one has run since 1988. More pics and info: https://www.undiscoveredscotland.co.uk/leadhills/railway/index.html
@UndisScot It would be great to have some sort of Feditag that covers sites such as this but also @AbandonedAmerica and others so it is easy to find similar resources.
There must be some great sites in England, Ireland & Wales too.
