The UK’s Network Rail is set to commence £31m of upgrade works between London and Scotland to enhance future passenger and freight rail journeys.
The railway will remain open during the development work for passengers who need to travel over the Easter bank holiday.
Network Rail has also minimised disturbance for passengers by adjusting its planned work.
The upgrade works at Bletchley, which will impact journeys between London and Birmingham, will be concluded before time to enable more trains to operate.
On the other hand, the essential work, which is to be executed in North London and Northamptonshire, has been rescheduled for completion before Easter.
Network Rail North West and Central region managing director Tim Shoveller said: “Our work will make the West Coast main line more reliable for our passengers and pave the way for HS2, which will bring much-needed extra railway capacity.
“There is no question such large scale improvements will mean changes for passengers, but we’re working with the industry to minimise disruption to passengers as much as possible. Our advice to people is to please check before you travel so none of this comes as a surprise while we carry out this vital work.”
Another set of major projects include a $17m (£12.3m) investment to build two new underpasses below the Bicester’s Chiltern main line and a $5m (£3.5m) project to renovate bridges at Warrington Bank Quay station.
In a separate project, Network Rail will also carry out the Gatwick Airport station redevelopment work.
The redevelopment work will involve track realignment and platform strengthening activity, which will enable the installation of broader platforms and additional lifts, escalators and stairs.
The construction of another bigger railway concourse will also take place, connecting the train station to Gatwick’s terminals.
Last month, Network Rail replaced an outdated signalling system with a modern, computer-based system in the Clacton-on-Sea area.
This new signalling system will help effectively control the movement of trains and offer improved live-passenger information.
