Having just read the article in "Rail", the full extent of the damage has become apparent. It explains some of David's pictures where the old timberwork was dug up.
As they are going back to redesigning and then recreating the sea wall and track bed, it will be some time before trains are running again for sure.
I am very surprised the "Rail Engineer" have made no mention of this ongoing job, I expect they are awaiting a conclusion. May be a long wait!!
