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.

Critical Rail Junction

Delivering infrastructure upgrades at one of Scotland's busiest and most strategically important railway junctions.

Legacy Infrastructure

Integrating new signalling power systems with infrastructure that had been in operation for more than five decades.

Operational Continuity

Maintaining reliable power to operational railway systems throughout delivery.

Collaborative Delivery
