A £53m scheme to redevelop Gatwick Airport railway station has been unveiled.
Network Rail said the scheme would provide passengers with more reliable and punctual journeys and easier access.
It involves creating a new platform and refurbishing the concourse, as well as upgrading the track and signalling.
Construction work is due to start next autumn and is expected to be completed by the end of 2013.
Network Rail said the station in West Sussex was the busiest airport station in the UK last year.
The proposal will be joint funded by Network Rail and Gatwick Airport.
Stewart Wingate, the airport's chief executive, said: "I am pleased that the station - a critical gateway to our airport - will now be developed to match the improvements we are making to the airport itself."
