Network Rail is set to embark on a programme of work worth in excess of £148 million over Christmas and New Year.
Once completed, passengers and businesses can expect better and more reliable infrastructure, together with improved facilities once they return to work.
It has been a chastening year for the railway industry, which has seen passenger services thrown into chaos at various times of the year.
The work as part of the five-year railway upgrade plan – which seeks to improve journeys for the months and years ahead – will start on 23 December and continue until 1 January, so the Christmas period will see services affected.
During this week or so, Network Rail will work on more than 330 projects throughout Britain across Christmas and New Year, with a workforce totalling 25,000 working around the clock.
It is an annual tradition for Network Rail, who use the holiday time to make much needed improvements across the whole railway network.
As part of the work, Network Rail will be upgrading overhead wiring system as part of the £250 million upgrade of the Great Eastern Main Line; elsewhere, new track will installed at Heathrow Airport junction which will improve reliability.
Andy Thomas, managing director of strategic operations at Network Rail, explained what the work will deliver to businesses and passengers.
He said: “This Christmas and New Year, thousands of rail workers will be working round the clock to deliver crucial upgrades to the rail network as part of the £50 billion railway upgrade plan.
“This huge investment programme will deliver more reliable infrastructure, improved facilities and services for passengers when they return to work.
“We know that our railway is up to 50% quieter than usual during the festive period so taking on and delivering these huge transformational schemes at this time of year minimises our impact on passengers who, so research shows, understand the need for such activity.”
