Six practices working on station designs.
- Hawkins/Brown at Tottenham Court Road
- John McAslan + Partners at Paddington
- Tony Meadows Associates at Bond Street
- Ian Ritchie Architects, at the Isle of Dogs
- Wilkinson Eyre at Liverpool Street
- Weston Williamson at Farringdon and Whitechapel.
Crossrail said the central area stations were originally designed in the mid-1990s. It said: "Current work includes reviewing the previous designs to ensure that they meet present-day standards and requirements but retain or improve the architectural quality achieved then."
McAslan and six other practices have been chosen to work on architectural studies for the routes of the link to Kingston and Ebbsfleet. These are: Acanthus Lawrence & Wrightson, Bennetts Associates, Building Design Partnership, Cartwright Pickard, Marks Barfield and Fereday Pollard.
Crossrail chief executive Norman Haste said: "This is a continuing selection process. We now have a top class group of architects."
Haste said that each of the stations would have a ticket hall at both end of the platforms.
The appointment of architects follows the decision by the government last month to throw its weight behind the scheme. Crossrail said last week it intended to finance the scheme through a mixture of PFI and the business rate.
