Network rail challenge developers to come up with 'destination' stations that will trigger regeneration.
Network Rail has released a shortlist of some of the biggest names in development to carry out the upgrades to Euston and Victoria stations.
Companies delivering proposals and through to the next stage at Euston are, British Land, Chelsfield Partners, Development Securities, and Hines.
For Victoria the shortlist comprises Development Securities, Hammerson, Land Securities and Stanhope.
Network Rail's commercial property director John Pike said: "We have come a long way in this process since we announced our plans for Euston and Victoria, last year."
"Over the next few months we will be getting more detail from the candidate developers as we work through the proposals and decide on the best way to realise the opportunity at these landmark sites."
The remaining developers continue through the selection process with a view to a preferred partner for each station being selected by Network Rail by the end of the year.
