Electrification and Plant Testing and Commissioning
Successfully delivering innovative Rail Electrification and Plant (E&P) testing and commissioning solutions across the UK rail network.
We test and commission critical Electrification and Plant (E&P) systems across the UK rail network, supporting the transition to low-emission, high-reliability infrastructure. Aligned with Network Rail’s CP7 strategic objectives and the UK’s Net Zero 2050 targets, our Rail Electrification and Plant Testing and Commissioning services ensure newly installed systems are safe, energised, and ready for operation.
Our E&P teams have extensive experience validating complex electrification systems — from HV/LV power distribution and switchgear to plant room assets and fixed electrical infrastructure. We specialise in testing works within rail-locked environments, managing access constraints and phasing with precision. Through systematic, cost-effective testing and handover, we help unlock the full value of electrification investments.

Specialised Rail Electrification and Plant Testing, Informed by Design Precision
Our Rail Electrification and Plant Testing and Commissioning services are built on a deep understanding of the entire E&P project lifecycle — from ES1 through to ES5. By aligning our testing processes with the original design intent and early-stage surveys, we ensure that every system operates exactly as specified.
Working closely with clients, principal designers, and delivery partners, we coordinate testing and energisation around surrounding assets and disciplines. This integrated, collaborative approach minimises disruption, avoids rework, and ensures each E&P system is fully validated for safe, efficient handover.
Transforming Rail Power Systems Through Precision Testing and Commissioning
At Softech Rail, we play a critical role in bringing rail power systems online — testing and commissioning substations, switchgear, transformer units, power cabinets, and distribution networks to ensure they are safe, reliable, and fully functional. We also support clients in validating long-lead assets such as HV equipment and modular enclosures ahead of energisation.
Our testing and commissioning teams work closely with internal delivery teams and specialist partners to carry out HV and LV system checks, continuity and insulation resistance testing, earthing and bonding verification, and functional tests across plant rooms and cable routes. With careful planning around access, safety, and live operations, we ensure each system transitions from installation to operational readiness with minimal disruption to rail services.
