In reply to GeoffM:
It'll be interesting to see what it does for climbing access in the gorge, nothing good would be my bet given the rockfall and congestion problems climbers would cause.
Frankly I can't see it working as a mass appeal tourist attraction especially if it's 'fenced' like the picture above suggests. That said, done right it has potential given the excellent rail connection to the fleshpots on the coast.
