Southern Rail have announced that work is about to start at Peckham Rye station to remove the existing shelters on Platforms 1 & 2 to replace them with a different kind. This is to make room for more passengers after the East London Line arrives on 9 December 2012.
Time will tell whether these new shelters give enough protection from the bad weather experienced on those platforms. Also a small waiting room is to be created on Platform 3 (not part of, but next to, the historic Old Waiting Room), and new toilets are being provided on platform 4.
