A new state-of-the-art signalling system is to be installed on train lines in the Norwich, Yarmouth and Lowestoft areas.
The work is being carried out as part of Network Rail's Railway Upgrade Plan, which will see £68m invested to modernise the railway and replace some of the oldest signalling equipment on the network.
A total of 66 new colour light LED signals, 22 power operated points and a remote computer-based signalling control system will replace levers and physical operations, which they say will mean safer and more reliable journeys for passengers.
Changes will also be made to level crossings to bring them up to modern safety standards. Level crossings that are currently operated by a crossing keeper will be replaced with a modern barrier remotely controlled by a signaller using CCTV cameras. Network Rail says this will improve journey times and reduce the amount of time the barriers are down, meaning fewer delays and congestion for motorists too.
There will be changes to services between Norwich and Lowestoft, and Norwich and Yarmouth for a nine-day period from Saturday, October 21, until Monday, October 30, while work is under way. Passengers are being advised to check before they travel during those times.
Meliha Duymaz, Network Rail's route managing director for Anglia, said: '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.
'I'd like to thank passengers for their patience while we carry out this important work and urge anyone using these services to check how their journeys will be affected ahead of travelling.'
The work will take place at several locations and there will be significant work on the Norwich-Yarmouth-Lowestoft lines between October this year and March 2019. This will result in changes to train services and passengers are advised to check before they travel by visiting www.nationalrail.co.uk or contacting their train operator.
