Network Rail is upgrading a key section of the Northumberland line and is now set to open the line again for passenger trains.
They are working to replace the railway bridge near Sharnford Close, Backworth, to allow more trains to cross the bridge in the future.
The engineers will also lay 200 meters of track between Thursday 25 and Tuesday 30 August.
The upgrades are part of a multi-million pound program called Restoring Your Railways, which will reintroduce regular passenger service between Ashington and Newcastle by 2024.
The program will allow the region to be more connected to Newcastle and open up opportunities for economic growth and better support the cities.
Work began in 2021, since then engineers have renewed more than eight miles of track and improved the Feather Bed Lane bridge to facilitate services in the future.
Network Rail Lead Sponsor Luke Durston said: “We are making fantastic progress on this unique and economically important program to bring reliable new rail service to communities in the North East.
“Over the bank holiday, we will be upgrading a vital section of this road, bringing us one step closer to restoring passenger services to south-east Northumberland for the first time in a generation.”
Glen Sanderson, Leader of Northumberland County Council, said: “It is great to see the progress the program is making and work like this clearly demonstrates the technical challenges we face.
“With benefits not just for Northumberland but for the wider region, each new structure or track improvement brings this fantastic project closer to completion.”
