Berrylands station, which is served by South Western Railway trains, has been earmarked for Network Rail’s improvement programme over the next five years.
Opened in 1933, it is one of the few remaining stations in London that still has wooden platforms.
Network Rail has now confirmed that the station will have to shut for more than three months next summer.
This means no trains will call at the station from May 11 until August 23, 2026.
According to Network Rail, work at the station will be focused on improving safety and ensuring a “reliable experience for passengers”.
Among other changes, both platforms will be replaced and widened, while new lighting, CCTV and information screens will be installed.
Network Rail has warned that disruption will include footway restrictions on Lower Marsh Lane, parking suspensions on Chiltern Drive and temporary road closures.
A spokesperson said: “While some works have been carried out over the years, including a platform extension in 2014, the structure is coming to the end of its operational life.
“We will work closely with local authorities to minimise disruption and will provide advance notice of any traffic changes.
“While some noise and disruption is expected, we will work hard to minimise this wherever possible.
“During the station closure, passengers will need to make alternative travel arrangement which might include using nearby Surbiton or New Malden stations or the K2 bus.”
Berrylands is currently marked as a station that would be served by Crossrail 2 trains, if the line is ever built.
This would see further work carried out to the station platform, as well as new lifts or ramps installed to provide step-free access.
Crossrail 2 would increase the number of trains that call at the station every hour from two to four.
