The collapse of the railway line at Dawlish last year generated major headlines but it's not the only stretch under threat. The coastal railway line from Carlisle to Barrow-in-Furness is one of the most scenic in Britain. In places it runs at the foot of cliffs immediately above the water. That means it's also one of the most vulnerable lines in the country, always at risk from the destructive power of the sea, or from rock falls, or from both. [From Richard Buckby]
