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.
