We’re upgrading signalling across Norwich, Yarmouth and Lowestoft
This investment to upgrade the signals is a vital aspect of our railway upgrade plan to provide a safe, reliable and efficient railway fit for the 21st century.
Our re-signalling project will improve:
- overall safety and reliability of the railway
- operational flexibility
- level crossing safety
- sustainability and efficiency using modern technology
- the duration of level crossing road closures reducing delays for road users.
We are modernising the Wherry lines between Norwich, Great Yarmouth and Lowestoft, by installing modern signalling technology controlled by a remote computer-based signalling system which will eventually replace the old Victorian signalling equipment currently in operation.
We are also replacing manually operated switches with powered switches controlled by a remote computer-based signalling system.
Keeper operated level crossing gates will be replaced with a modern barrier type remotely controlled and operated by a railway signaller using CCTV.
When our upgrades are complete, it will help to provide the level of reliability that our passengers expect from a modern railway.
The programme includes the following improvement work:
- Upgrades to signalling, track, power systems and telecoms.
- A new platform extension at Brundall station.
- Track remodelling on four lines for modern train operation.
- A new power supply system for the new signals.
- Upgrade of six level crossings with barriers and traffic light protection.
- Installation of stop lights at 11 user worked crossings for improved safety.

Progress so far
We have made good progress since starting work in October 2017.
The first phase of the project was completed in October 2017 during a nine day line closure to upgrade the track around Great Yarmouth and Somerleyton stations, improving the way we operate and control the railway.
In Great Yarmouth, the manually operated station track points (which allows trains to cross between lines) were upgraded to powered operation which allows us to control the track switch remotely. We also removed redundant equipment from the railway to keep it tidy.
In February 2018, we had our second phase of work to begin to install the foundations for the new signals across the route, and we upgraded the junction around Lowestoft.
In October 2018, we completed the third phase of the project by remodelling the track layout at Reedham junction over nine days, renewing over 1000 metres of track which will improve reliability and operational efficiency of the railway. We also installed over 26 new signals, equipment and cables ready for the signalling change over planned for 2019.
The changes to Reedham junction will also require rail services between Reedham and Yarmouth to be suspended from 20 October 2019 until the date when the new signals are expected to come into operation. The closure of the single branch line will affect a small number of daily services via Berney Arms.
All of this work is being done in preparation for the final switch over from a Victorian era signalling system to a modern signalling system. When completed, the Wherry lines will be using a modern signalling system which will improve the journey for passengers.
