GC Partnership have been commissioned to undertake the design and cost management associated with the rebranding works involved in the transition of nine Southern Railway stations to London Overground stations from New Cross Gate through to West Croydon. 

In addition to rebranding and improvements to the station structures and fabric, all stations will be refurbished with CCTV coverage, Help Points, customer information systems, passenger announcements, improved lighting and better signage. These works form part of the overall expansion to the London Overground Network.

Other sections of the Southern and Southeastern networks are due to change to London Overground with works ongoing up to 2012 when an orbital route around London will be in place.
