The East Sussex Re-signalling scheme fell under the Sussex & Wessex signalling framework contract awarded to Atkins by Network Rail.

The scope of the East Sussex scheme included various renewals and upgrades to the existing signalling infrastructure, but in essence the main deliverable was to close six signal boxes and to re-control them from Network Rail’s new signalling control centre at Three Bridges.

The re-control itself centralised the control of all signals, points and level crossing equipment.

Aside form the main scope a new train describer was provided, new line side telephones and track circuits were installed, an uninterrupted power supply for new 650V feeders, axle counter provision with remote reset and restore facilities, old semaphore/shunt signals were renewed with LED signals, along with the complete renewal of Ripe and Wilmington AHB’s. Where possible the line speed of KJE3 line was increased to 90mph to reduce current train journey times.

During the de-commissioning of the signal boxes all mechanical interlocking and mechanical points operating equipment was recovered. The mechanical points were replaced with a more modern Clamplock system to improve reliability and performance. The above changes resulted in a more reliable infrastructure for running trains and has increased train punctuality. RTIS supported Atkins on this project with skilled signalling teams for a period in excessive of 9,500 man hours. They were particularly commended for their expertise and knowledge in renewing all the signalling equipment to 5 level crossings, whilst also being highly praised for their efforts and contribution throughout the 8 month project.
