It must not be fix the funicular at any cost. The unthinkable is not unthinkable anymore!
I agree, but I dread to think how much it will cost - and how long it will take - to decommission the damned thing and re-instate the mountainside.
Potentially doing it over a long timescale might reduce the cost and make reinstatement of the ground simpler. It also depends on where the most complex problems are - could the Funicular being shortened with a new classic ballast track passing loop built half way up the White Lady with the Sheiling the terminus be done for a fraction of the full refit with a new lift to mid-station level?
The bottom section could then be gradually nibbled away at when ground conditions were favourable, without the pressure of the Section 50 conditions.
HIE needs to be transparent here and provide clarity of whether it is some beams, some piers, or a systemic system wide issue with the entire viaduct structure.
