Rail users in parts of northern England are facing weeks of disruption after a major landslide caused by movement in a huge colliery spoil heap next to the railway.
It left some of the track, at Stainforth, south Yorkshire, grotesquely twisted, meaning that services between Doncaster, Scunthorpe and Cleethorpes will be suspended for at least eight weeks.
Local mayor Arlene Abbot said if the collapse had gone the opposite way it could have resulted in another Aberfan - the devastating south Wales disaster in 1966.
