Network Rail has released a shortlist of developers for the upgrade of Euston and Victoria stations in London.
Those delivering proposals for Euston are: British Land, Chelsfield Partners, Development Securities and Hines.
The ones chosen for Victoria are: Development Securities, Hammerson Land Securities and Stanhope.
They will be asked to turn the two venues into "destination stations" that can be catalysts for regeneration through commercial development and retail, office, residential and leisure facilities.
John Pike, Network Rail's director of commercial property, said: "Over the next few months we will be getting more detail from the candidates as we work through the proposals and decide on the best way to realise the opportunity at these landmark sites."
Land Securities has teamed up with architect Hamilton Associates for its bid to redevelop Victoria Station, and Stanhope has recruited John McAslan + Partners. Other developers declined to reveal which architects they had signed up.
In Manchester, Network Rail has asked four teams to submit detailed proposals for the redevelopment of the area around Manchester Victoria Station, including several buildings next to the station. They are: Amec Developments with Morley Fund Management; Argent; CTP with Development Securities; and Lend Lease.
