This is the largest single contract to be awarded by Network Rail under the Major Signalling Framework Agreement (MSFA) during this control period.

The re-signalling project will replace existing systems covering 125 miles of track in the Cambridge area with modern signalling technologies. This will provide a platform ready for digital technologies like ETCS.

Alstom has been tasked with replacing almost 700 items of signalling equipment, upgrading signalling safety interlocking equipment and signalling control equipment at Cambridge power signal box.

It’s also been contracted to relocate the control of signalling to the Cambridge power signal box, decommission three mechanical signal boxes, upgrade seven level crossings from half barrier to full barrier and renew telecommunications and power supplies to support the new systems.

Ellie Burrows, Route Director for Anglia at Network Rail, said:

“Signalling systems are crucial to operate a safe and efficient railway for passengers, freight and everyone that uses or interacts with the railway.

“This project will provide a signalling system fit for a modern 21st century railway in the Cambridge area, and working with Alstom we will improve the reliability and performance of the railway now, and for future passengers in the decades to come.”

Design work has already begun and work on the ground will be delivered over four commissioning stages to minimise disruption.

The final commissioning of the new system is scheduled for winter 2024.

The completion of this project will enable the delivery of wider re-signalling works across the Anglia, including future integration with the proposed new Cambridge South station, as well as the potential future integration with East West Rail.
