Just to keep you informed - here's the latest update I received on the works at Brockley Station on 14 July. I have followed this up with a further request today as whilst progress is being made on the works - it isn't at all clear that it will be finished anytime soon.
"Dear Cllr Walton
We are urgently discussing progress on this scheme with the contractor. We are concerned to get the steps opened as quickly as possible.
I will advise you as soon as I have firmer information."
