Network Rail has released a series of images taken by drone to reveal the full size and scale of the repairs following the landslip on the Settle to Carlisle railway at Eden Brows in February 2016.
Network Rail has described the work as the “most complex railway repair” it has ever undertaken.
The ground failure triggered the movement of more than 500,000t of material and called for strengthening of a 70m high section of embankment.
Repairs, which enabled reopening in March 2017, are estimated to have cost £23M.
The remediation included installation of 226 20 to 30m long steel piles to support a concrete track base to protect the rail route from any future ground movement.
“It’s not until you see the aerial shots that you appreciate the sheer scale of this repair,” said Network Rail London North Western route managing director Martin Frobisher. “The landscape is as rugged as it is beautiful. The Victorians certainly did choose a wonderful spot to build a railway.”
Friends of Settle Carlisle Line’s Mark Rand said: “Eden Brows suffered a massive landslip when the line was being built in the 1870s. History repeated itself in 2016. That work of this scale has been done in such fine style underlines the strategic importance, and tremendous potential, of this line.”
Work on the repair will continue until March 2018 with rock armour defences being installed within the River Eden to protect the slopes during future flood events and replanting of woodland.
