In some sections of the tunnel, the rock is more unstable and requires more extensive work.
One of the roof falls in a stone-lined section of tunnel before restoration work started.
In the rock lined sections of tunnel, where the surface is loose, a steel mesh is being spread across the roof and walls. This may be left like this in some places where there is only a risk of a few loose stones.
In most places, the mesh will be used to re-inforce concrete which will be sprayed onto the walls and roof.
These pictures give a good impression of the unevenness of much of the tunnel surfaces.
Scout Tunnel, between Stalybridge and Mossley, is rather like a miniature version of Standedge Tunnel, with lined and unlined sections, and requiring similar remedial work.
