The rail operator is looking to establish its first 50-50 joint venture with a developer for eight of its station sites , which is part of a £4bn , 10-year overhaul of the station network.

The project is expected to attract interest from large property developers such as Land Securities , British Land and Hammerson , as well as brownfield site developers such as St Modwen given the nature of the land around the stations.

The sites initially earmarked for development are Twickenham , Guildford , Wembley Cutting , Walthamstow Central , Enfield Town Station , Epsom , Maidstone East and Paddington Enterprise House. In total, there are about 20 acres of development land.

Network Rail will contribute the land as its half of the deal , the value of which will be matched with cash by its development partner.
