Network Rail will carry out track maintenance works between Marks Tey and Chelmsford on the London to Norwich mainline in September, October and November
Keeping the track in good condition is essential for the safe and reliable running of rail services. The busier the network, the more worn track becomes over time.
Engineers keep on top of repairs and maintenance throughout the year to prevent delays caused by track issues. The switches and crossings units enable trains to change from one track to another which is essential for diverting rail traffic if there’s an issue ahead, to minimise delays.
The stones that make the trackbed are called ballast and it is essential for keeping the track stable, prevents growth of vegetation and allows water to drain away to keep the sleepers dry.
Over time, the ballast wears down and fine pieces of granite, like sand, are created when the stones rub together as trains pass. This all sticks together when combined with water, turning the ballast into a lump of concrete which hinders drainage and the flexibility of the ballast to constrain the track as it moves under traffic.
Ballast cleaning removes the worn ballast, screens it and replaces the old ballast with new angular ballast. This helps prevent delays caused by flooding, landslips and track issues.
Other routine track, signalling and overhead line maintenance works have also been scheduled to make the most of the closure.
Improving performance on a key network
Jamie Burles, Greater Anglia managing director, said: “This track maintenance work will help to improve punctuality and performance along this key part of our network.
“We will be running a rail replacement bus service while the work takes place, so customers will be able to complete their journeys.
“Passengers should check before they travel, allow more time for their journey and wear a face covering when travelling by train or rail replacement bus and at our stations.
“We have several measures in place to keep customers safe including regular cleaning and sanitisation of trains and stations, and high levels of face-covering compliance.
“We would like to thank customers for their patience while this work takes place.”
Ellie Burrows, Network Rail’s route director for Anglia, added: “This package of work is essential to keep services running safely and reliably between Norwich and London and to minimise delays.
“I advise passengers to check before they travel and thank everyone for their patience while we carry out this important work.”
