Network Rail will spend more than £30 million on engineering projects over the May 28-30 Bank Holiday weekend.
More than 9,000 members of the Orange Army will work at sites across the UK.
Projects include: overhead line electrification work south of Shenfield, in preparation for Crossrail; completion of the £250m capacity improvement at Norton Bridge; laying new track at London Bridge ahead of the opening of the first half of the station’s new concourse this August; and the penultimate stage of a signalling upgrade in Bristol, as part of the Great Western Electrification Programme (GWEP).
At Bermondsey, NR is installing a new set of points enabling trains to use the new Bermondsey dive-under when it is completed next year.
In Bristol, a road bridge is being demolished and replaced by a new structure that can support the overhead line equipment structures needed for GWEP.
