Network Rail has is carrying out a series of rail upgrades across the country.
One of the schemes in question relates to the Anglia route, while the other will benefit the London North Eastern & East Midlands route.
On the Anglia route, Network Rail is installing a signalling system on the Norwich, Yarmouth and Lowestoft areas of the rail, which is part of its Railway Upgrade Plan.
This modernisation will focus on making journeys safer and more reliable, with old signalling equipment set to be replaced.
Levers and physical operations will be replaced as part of this £68 million investment by new colour light LED signals, power operated points and a remote computer-based signalling.
The Managing Director for Anglia, Meliha Duymaz, described this project as “significant.”
“This is a significant project that will not only transform rail travel for passengers in this region, but also bring benefits for motorists and pedestrians.
“We are working to provide a sustainable and efficient railway which uses modern technology, to improve safety and reliability as part of our Railway Upgrade Plan.”
This project will start next month and should be completed by March 2019.
Elsewhere, Network Rail announced a £1.5 million upgrade project that will see improvements carried out to a railway bridge which is between Spalding and Sleaford.
Also part of the Railway Upgrade Plan, the work will include the demolition of the existing bridge to be replaced by a new, ready-made bridge that will be installed in its place.
This work is considered crucial because the development will go some way to ensuring the bridge is strong enough to carry heavier freight trains.
Given that the rail freight industry is worth £870 million to the UK economy every year, it is an important project.
Work to install the new bridge has been ongoing since July, but next month will see the main work commence and also finish.
