We are installing 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 will replace the system which uses mechanical levers and pullies to change signals and track points to allow trains to switch between tracks. The new system will be controlled from a powered signal box at Colchester. 

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

Benefits of the programme

These works are a vital part of our strategy to provide a safer, reliable and more efficient railway putting our passengers first. The work will:

  • Improve the overall safety and reliability, reducing faults which cause delays
  • Support a more sustainable and efficient railway using modern technology
  • Help reduce ongoing maintenance as the new mechanical equipment will be more reliable meaning we can reduce costs and it will be less disruptive to the railway in the future.

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

When are we going to deliver this work?

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

We will be carrying out intensive works on the project for 23 days from Saturday 20 February 2021 to Sunday 14 March 2021 and over selected weekends.

Across weekends in September and October 2020, our teams successfully completed the preparatory works ahead of the intensive works in February and March. We’ve now installed 13 new OLE structures, 2 new Relocatable equipment buildings, a new power supply, 6 new signal foundations and over 6000m of new cables.

Will this work affect train services?

Mid-week during the intensive works there will be Monday to Friday rail replacement bus service between Clacton and Frinton. Trains will run between Walton and London.
