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.

£37m investment – signalling, track, overhead lines, power systems and telecoms

500m newly laid track – as part of the new track layout to achieve greater reliability and minimise disruption

12 Renewed Signals – solid state interlocking system with modern LED Signals

12 Renewed Points – power operated and linked to the new signalling system

11 New OLE Structures – and OLE infrastructure alterations in line with new layout

2 New Power systems – for the signalling and points heating equipment

Modernised Signalling System – to renew the obsolete signalling assets

Colchester Powered Signal Box – to renew the obsolete signalling assets

When did we complete the work?

The early preparation works began in the winter of 2019 and progressed throughout 2020 with major works required throughout winter/spring 2021.

We carried out intensive works on the project for 23 days from Saturday 20 February 2021 to Sunday 14 March 2021.

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 compliments Greater Anglia’s new fleet of trains and delivers a better, overall journey experience for passengers.
