profound.\u00a0 Reopening the line will be exceptionally difficult without very large-scale engineering works.\u00a0 Further retrogression of the landslide will lead to the loss of these historic buildings.\u00a0 In turn, the landslide will be causing widespread economic costs through the region through the loss of both communication links and tourism.<\/p>\n<p>This does seem to be an issue
