I want to know the answer to the following question:
In feet, how much of the Dawlish sea wall was destroyed?
All the background I'm provided with is that "On the night of 4 February 2014, amid high winds and extremely rough seas, part of the sea wall at Dawlish was breached washing away around 40 metres (130 ft) of the wall and the ballast under the railway immediately behind.". Is that enough to answer the question?
Answer: yes
