Thousands of passengers facing delays as Brighton Main Line to shut for nine days for £15m upgrade

ITV News Meridian's Tom Savides reports on what the closures will mean for commuters


People are being urged to plan ahead as the Brighton Main Line is due to shut for nine consecutive days to upgrade the line.

The railway between Three Bridges, Brighton and Lewes will close from Saturday 19 to Sunday 27 February. Engineers will rebuild a crucial junction, lay brand new track and shore up embankments to reduce the risk of landslips.

The upgrades will cost around £15m to complete, which includes the replacement of more than 1,500 metres of track.

Southern and Thameslink will operate alternative train and bus services, but commuters are being warned that many journeys will take considerably longer than normal.

The Brighton Main Line is one of the UK's busiest routes, with the infrastructure among the oldest used.

Network Rail bosses say the nine-day closure will mean the work can be done quicker.

Katie Frost, Network Rail’s Sussex route director, said: “Doing the work in a longer 9-day closure means we can get more work done, more quickly, avoiding 20 separate weekend, evening and bank holiday closures which would be even more disruptive to passengers, the people who live by the railway and the wider economy."

When asked why the work was not done during lockdown when less passengers were using trains, Ms Frost said: "Our staff have been working tirelessly throughout the pandemic, keeping the country moving - works of this scale aren't off the shelf.

"We have had these in the planning for a number of years. And so that's why, whilst we appreciate there is never a good time to shut the railway, doing it now and in this way we know is the least disruptive we could possibly make it."
