Gatwick Airport has announced a £120M project to upgrade its train station.
The rail station at the Sussex airport will see its concourse doubled in size and provision of extra lifts and escalators.
Work is scheduled to start in 2017 and complete in 2020, giving passengers a smoother journey from train to plane.
Gatwick and Network Rail will contribute £30M each to the scheme, with £10m from the Coast-to-Capital local enterprise partnership and £50m from the government.
Demand at the station is forecast to increase by a third to 20M rail passengers a year by 2025.
Gatwick chief commercial officer Guy Stephenson said: “This agreement is a great example of the private sector and government working together in partnership to deliver a game changing and affordable project for the future.
“This new station builds on the ongoing transformation of Gatwick Airport and will deliver a first-class gateway for visitors, air passengers and the 1M rail commuters who use Gatwick station every year.”
