A major £115 million upgrade of Manchester Airport station is set to begin this winter.
The investment will see platforms one, two and three extended to allow more trains to serve the station.
Track layouts on the approach to the station will also be upgraded, while signalling systems will be modernised.
Network Rail and contractor Kier will deliver the project between now and 2028 as part of the wider Manchester Rail Upgrade programme.
The work hopes to create additional capacity, support the operation of more trains and help deliver more reliable and efficient journeys for future rail passengers.
The project is intended to improve connections to Manchester Airport.
Rail Minister Lord Hendy said: "Manchester Airport is a vital transport hub and this £115 million investment from government will deliver more reliable services, increase capacity, and improve connections for the millions of passengers who use the station every year.
"This is the sort of improvement Great British Railways will be designed to deliver.
"By bringing track and train closer together under public ownership, we can take a more joined-up approach to investing in the railway, improving performance, putting passengers at the heart of every decision and growing the economy in the North."
The first major stage of the programme will take place on Sunday, December 6, when Manchester Airport station will close for one day.
During the closure, engineers will install a utility bridge across the railway to house electrical cables.
The work will allow a bridge structure used by Manchester Airport Group to be removed at Easter 2027 before a replacement is constructed later in the year.
Simon Daly, Network Rail senior sponsor, said: "This £115 million investment represents a major commitment to improving one of the country's most important transport interchanges.
"Manchester Airport station plays a vital role in connecting people across the country so these improvements will create more capacity for passengers, allow longer trains to serve the station and improve the reliability of services for years to come.
"The station closure on December 6 is an important first step in delivering these benefits.
"We recognise that any disruption is inconvenient and have worked closely with our partners to put plans in place, so passengers are kept on the move."
Manchester Airport station will reopen as normal on Monday, December 7.
Rail replacement buses will operate between Wilmslow and Manchester Airport during the closure, while Metrolink services will continue to run as normal.
Passengers planning to travel to or from the airport by rail are being urged to check their journey before travelling and allow extra time.
