[[File:OS Folly Point 1901.JPG|thumb|300px|right|1901 OS Map showing Folly Point and the Elan Valley Aqueduct]]Folly Point is situated between [[Bewdley ]] and [[Arley]], or more specifically between [[Northwood Halt]] and [[Trimpley Reservoirs & Waterworks|Trimpley Reservoir ]] north of milepost 139½. It is the narrowest part of the valley along the line, with the River Severn running close to the line and around 40 feet below it. This has made the area prone to landslips both in history and preservation.
A major slip in [[Severn Valley Railway Timeline 1980-1989#1980 | 1980]] required excavation of the formation, the insertion of stone filled ‘gabions’ and the lifting of the track by around 18 inches over a length of some 60 feet.<ref name=JM>[[Bibliography#Books|Marshall (1989)]] p. 95.</ref>
