Is anyone aware of any detailed info about the Network Rail sponsored
alterations for the ELL at Crystal Palace, West Croydon and South Croydon
(new to me too), apparently due for completion Feb 2009 according to this
short summary found by Google:

http://www.colasrail.co.uk/east_london.htm

I've read elsewhere that the West Croydon alterations produce a 'centre
turnback', but don't Southern use a bay at one side at the moment?

Is this flagging up a possibility of some Southern services moving to South
Croydon to make more room for the ELL's 4 tph service turnbacks at WC?
Seems that this area of the ELLP works is not as well documented than all
the stuff in the core section and around New Cross Gate...
