Electrification & Plant (E&P) Engineering
Electrification & Plant (E&P) systems sit at the heart of safe and reliable railway operations. From traction power supply to depot infrastructure, effective integration of LV and HV systems underpins modern rail performance.
At OSL Global, we provide integrated E&P engineering support from our offices in Crewe and Swindon, delivering design-to-commissioning services across the UK rail network.
Integrated Rail Power and E&P Capability
Our Electrification & Plant capability includes:
Design, installation and testing of LV and HV substations
Functional Supply Points (FSP) and Auxiliary Power Supply Points (PSP)
Points heating, depot power and station electrical systems
Distribution Network Operator (DNO) interface coordination
Full-system load analysis using ETAP software
UPS and generator design, installation and asset integration
Isolation planning and engineering management within operational rail environments
Working within live rail and depot environments requires disciplined engineering management, clear responsibility allocation and robust interface coordination across signalling, civils and telecoms teams.
OLE Isolation Planning and Engineering Management
Effective isolation planning is critical to maintaining safety and programme certainty during rail works.
OSL provides structured isolation planning and engineering management support for electrified rail environments. We coordinate technical planning, sequencing and interface control to ensure works are carried out safely and compliantly. Where physical switching is required, delivery is undertaken in collaboration with approved and competent partners.
This integrated model allows us to maintain engineering oversight while ensuring safe execution within operational depots and mainline environments.
Supporting Rail Infrastructure in Crewe and Beyond
Crewe remains a strategic rail hub within the UK network, supporting maintenance, freight and passenger operations. From our Crewe office, OSL supports projects across the North West, Midlands and wider network, providing local engineering expertise backed by national delivery capability.
Similarly, our Swindon office enables support across the South West, Thames Valley and Southern regions.
By combining regional presence with multidisciplinary engineering capability, we deliver resilient and compliant E&P solutions across both renewals and new infrastructure schemes.
Design-to-Commissioning Rail Engineering
From early feasibility and load analysis through to installation oversight and commissioning support, our E&P services are structured to reduce interface risk and strengthen programme certainty.
Electrification and power integration may sit behind the scenes, but they remain critical to safe and efficient railway performance.
