Almost 14,000 people will work across the rail network over Easter, as part of an investment in excess of £100 million to upgrade infrastructure and facilities.
Part of the five-year Railway Upgrade Plan, the Easter projects will see 13,800 work around the clock to deliver work that will ultimately improve passenger experiences in the coming weeks and months.
Infrastructure will be made more reliable, and facilities will be upgraded.
During the Easter holidays, a number of significant projects will be undertaken on the line by Network Rail, responsible for managing and operating the vast majority of the rail network throughout England and Wales.
The work will include significant work across the West Coast Main Line, from London Euston to Glasgow.
This unfortunately means that trains will not run to or from London Euston station between 19 April to 22 April, as work will be undertaken on the line in London, Preston and Glasgow.
Elsewhere, work will see reliability of the line between London Fenchurch Street station and Barking improved by replacing two bridges and renewing the track; like London Euston, this means trains will not run during this time.
Electrification work in the form of installation of foundations, masts and overhead line equipment will take place between Cardiff Central station and Severn Tunnel.
This work underlines the importance of electrification; although some potential projects have been scaled back over the last year, recent reports have reiterated its position as the most beneficial way to upgrade intensively used routes.
To that end, Southend Victoria branch line will also see its overhead wiring system upgraded; this in itself is part of a wider £46 million investment.
Network Rail say the work is necessary given the huge spike in passenger numbers on the railway over the last decade; stations and platforms are, therefore, not designed for the demand they now receive.
The work over Easter will help to meet the aims set out in the Railway Upgrade Plan to transform millions of passenger journeys.
