RAIL passengers are being urged to check before they travel during the upcoming bank holiday weekend.
Network Rail will be spending £30m on three days of upgrade work from May 28 until May 30.
More than 9,000 staff members will be working round-the-clock to deliver the upgrade, which includes renewing the track, upgrading signalling systems and boosting capacity.
In the south, the majority of the network will remain open over the holiday, though overnight works will result in changes to services in the Bournemouth area until around 9.30am on Sunday.
However, passengers travelling across the country may be affected by upgrades in other regions.
John Halsall, route managing director, said: ‘Most of our upgrade work won’t cause any disruption, so the overwhelming majority of passengers will be able to use their trains without interruption.
‘However, there’ll be major work taking place elsewhere so I’d still urge everyone to check before they travel.’
