As a daily user of Potters Bar Station. I've recently noticed a sign go up explaining (without details) that the underpass through the station is no longer a thorough fare. This is due (somehow) to "Health and Safety" Does this mean the station is dangerous? Will having a valid ticket save us from some terrible calamity? I seem to have missed the memo we all got in this country informing us that we must all be wrapped in cotton wool before we leave the house (and presumably in the house) in case we come face to face with reality.

Anyone know what's going on?

I saw that sign very strange, says it one end but not the other. So coming one way is safer than another!!!?
