Alstom has successfully modernized the signalling system at South Kirkby in West Yorkshire, improving the journey for passengers. The outdated manual signalling, installed more than 50 years ago on the East Coast Main Line, was replaced due to its obsolescence and increasing maintenance challenges.
The new automated system enhances the efficiency of signal and point operations, leading to better punctuality for passengers. It also improves safety for Network Rail personnel by providing more accurate monitoring of train locations on the tracks.
A key feature of the upgrade is the installation of Alstom’s Smartlock400, a computer-based interlocking system operated from the York Rail Operating Centre. This system prevents conflicting train movements through junctions and crossings, ensuring safety.
Joanne Boocock, Digital and Integrated Systems Project Director at Alstom, said, “The successful completion of the South Kirkby resignalling project highlights the strong collaboration between Network Rail, Alstom, and our supply chain partners. We’re proud to offer innovative, future-ready solutions, such as the computer-based interlocking system, that will enhance both railway reliability and performance for passengers and freight services.”
The project included a full update of lineside equipment, installation of new power supplies, feeder cables, and casings, along with 26 new signals designed to improve train flow. To further protect Network Rail staff, new warning systems have been installed along the 17-mile stretch, along with safety features that allow workers to isolate sections of track for critical maintenance tasks.
Paul Carabine, Senior Project Engineer at Network Rail, commented, “The changes introduced by the South Kirkby resignalling project will improve reliability and safety for both passengers and trackside staff. By combining this with other nearby projects, we’ve minimized disruption for future services and ensured the system is ready for future digital integration.”
This upgrade is expected to save 880 staff maintenance hours annually, and the new system is compatible with the European Rail Traffic Management System (ERTMS), a key part of the UK’s ongoing rail modernization efforts.
