Developers in the running include British Land, Grosvenor, Development Securities, More London and Stanhope.
Network Rail has announced shortlists of developers for its planned revamps of Victoria and Euston stations in London.
The rail operator has selected some of the biggest names in development for the massive mixed-use regeneration schemes.
Five developers - British Land, Grosvenor, Development Securities, More London and Stanhope - have been shortlisted for both projects.
On the 100,000 m2 Euston project, Sir Stuart Lipton's Chelsfield Partners have also been nominated along with Hines.
The choice raises the prospect of Sir Stuart going head to head with his former employer, Stanhope, for the development.
At Victoria, which could bring up to 75,000 m2 of mixed-use space, Hammerson and Land Securities are also in the running.
Network Rail deputy chief executive Iain Coucher said: "We were impressed with the high quality of the companies that expressed interest in these schemes.
"Now with a shortlist in place for both projects, the competition begins for the once-in-a-generation opportunity to transform these stations and contribute to London's growth."
