The evolution of signalling power

The evolution of signalling power

For many years, Unipart Rail has been providing the rail industry with a full suite of signalling solutions, ranging from fully assembled Signalling Location Cases to Relocatable Equipment Buildings.

Manufactured and tested within our dedicated Service Centres, our signalling solutions are well established within the marketplace and have gained an excellent reputation for their high quality and performance.

A Single Source Partner

Over recent years the requirement for signalling power has evolved, with the introduction of Class II

To support this evolution, Unipart Rail has developed the PowerU range – a complete range of signalling power products, which includes applications for new installations through to legacy upgrades and SIN 119 – positioning us as a single source partner for all signalling power requirements.


Safety is paramount

Electrical shock prevention is the reason for the existence of Special Inspection Notice 119 (SIN 119). Safety is something that we take very seriously in our products as well as in the day to day running of our business. The products we manufacture are all assembled and individually tested in-house and comply with all the relevant Network Rail standards. This testing allows for greater traceability, safety and quality assurance, which saves time for our customers as the units are provided ready to fit.

Our acquisition of Samuel James Engineering has also extended our capabilities throughout the Power Supply sector, now giving us end-to-end power management solutions for the railway.

Our PowerU Product Range includes:

  • Functional Supply Points – FSP01/02, FSP03 and FSP04
  • Terminal and Earth Continuity boxes
  • Transformers, Enclosures & Pedestals
  • Earthing Products
  • Cable Products
  • PowerU Annex
  • DITA – Distribution Interface Transformer Assembly
