We’ve installed a new signalling system in the Clacton-on-Sea area to replace the Victorian equipment with modern technology, bringing it into the 21st century.

The new computer-based signals have a replaced a system which used mechanical levers and pullies to change signals and track points to allow trains to switch between tracks. The new system is now controlled from a powered signal box at Colchester.

Alterations have been made to the overhead line equipment and the track layout has been remodelled and updated to cater for a modern railway with powered switches and crossing controlled by the new signals.

Benefits of the programme

The upgrades have provided a safer, more reliable system and help us reduce faults which cause delays for passengers as they return to the railway. The modern technology supports a more sustainable, efficient railway and helps reduce ongoing maintenance costs as the new equipment is more reliable.

The new signalling system complements Greater Anglia’s new fleet of trains and delivers a better, overall journey experience for passengers.

Winners at the National Rail Awards! 

On Thursday 16 September, the National Rail Awards ceremony was held, and the Clacton-On-Sea re-signalling project was lucky enough to win an award. 

There were some great contestants in the running, but we managed to scoop the winnings for the award, ‘Outstanding Teamwork’, for our collaboration with Atkins, Greater Anglia and partners for this project.  

Thank you to all involved who helped complete this project in February 2021.
