OVERVIEW

PROJECT BY NUMBERS

Appointed by Siemens Mobility, Kent Group played a key role in the Carstairs Modernisation programme, delivering specialist signalling power infrastructure at one of Scotland's most strategically important railway junctions. Over a two-year programme, our teams supported the modernisation of critical electrical assets that underpin passenger, freight and cross-border rail services, helping to enhance the long-term resilience and reliability of this vital section of the network.

Working safely within a live operational railway, Kent Group delivered a comprehensive package of signalling power works including a new Principal Supply Point (PSP), Auxiliary Supply Points (ASPs), DNO supplies, point heating infrastructure, MOS power supplies and more than 10 kilometres of new cable.

Through close collaboration with Siemens Mobility and Network Rail, the project successfully introduced resilient, future-ready power infrastructure while maintaining operational continuity throughout delivery.

THE SOLUTION

Kent Group delivered the specialist signalling power infrastructure required to support the wider Carstairs Modernisation programme.

This included the installation of a new Principal Supply Point with resilient 650V and 400V distribution, Auxiliary Supply Points, DNO cabinets, point heating power supplies, MOS supplies and extensive cable infrastructure.

The project also introduced the railway's first Bender RS4 Tier 1 insulation monitoring and fault location system, providing enhanced fault detection and improved operational resilience.

"Carstairs is one of Scotland's most strategically important railway junctions, making reliability and resilience absolutely critical.

Our role was to provide the specialist signalling power expertise needed to support the wider modernisation programme, delivering infrastructure that will serve the railway for many years to come. This project demonstrates how technical innovation, collaborative working and specialist engineering expertise can come together to improve the long-term performance of some of the UK's most important rail assets.

I'd like to thank Siemens Mobility and Network Rail for the strong partnership that helped make this project a success."
