03Delivery-Focused Engineering Support
Whether depot electrification, renewals or complex diversions, our designs prioritise buildability, programme certainty and operational safety.
Rail Electrification Design (AC & DC)
We deliver comprehensive AC and DC rail electrification design services across new infrastructure, renewals and enhancement schemes.
Our experience spans overhead line equipment (OLE), DC conductor rail systems and associated traction power interfaces, providing fully coordinated and compliant design solutions.
From concept development and option selection through to detailed design and Approval in Principle (AIP), we work closely with clients and contractors to develop buildable, integrated electrification systems aligned with operational and safety requirements.
Our designs are developed with careful consideration of system interfaces, maintenance access, environmental constraints and future expansion, ensuring resilient and future-ready railway infrastructure.
Through a structured and collaborative approach, we support safe installation, efficient delivery and long-term asset performance across live railway environments.
DC Conductor Rail & ETE Design
We provide specialist design services for DC conductor rail systems and associated Electrical Track Equipment (ETE), supporting both new installations and renewal programmes. Our expertise covers third and fourth rail arrangements, bonding strategies, negative return systems and interface coordination with signalling, civils and permanent way disciplines. Designs are developed in line with current standards and operational constraints, ensuring safe integration within live railway environments. From feasibility and option development through to detailed design and construction support, we prioritise safety, maintainability and efficient delivery. Our structured approach ensures compliant, robust and future-ready DC traction power solutions that support reliable railway performance.
Substations / HV Feeders / LV Systems
We deliver comprehensive traction and non-traction power design services covering substations, high voltage (HV) feeder systems and low voltage (LV) distribution networks.
Our experience includes transformer and switchgear layouts, protection and control systems, cable routing and earthing strategies, ensuring fully coordinated and compliant power infrastructure solutions. Working within operational railway environments, we develop designs that consider resilience, redundancy and safe access for maintenance. From concept and load assessment through to detailed design and technical approvals, we focus on reliability, system integration and long-term asset performance. Our approach supports safe energisation, efficient installation and dependable railway power supply across complex rail networks.
Depot Electrification
We provide specialist electrification design services for rail depots, stabling facilities and maintenance environments.
Our experience covers OLE and conductor rail arrangements within constrained operational settings, including isolation strategies, safe access planning and coordination with mechanical and plant systems. Designs are developed with a clear understanding of depot operations, vehicle movements and maintenance requirements, ensuring safe and practical solutions. From concept design through to detailed delivery support, we focus on buildability, maintainability and system resilience. Our approach ensures electrification infrastructure that supports efficient depot operations, safe working practices and long-term asset reliability.
Renewals, Upgrades & Diversions
We support electrification renewals, system upgrades and complex diversion projects across live railway environments.
Whether replacing life-expired assets, enhancing capacity or facilitating third-party developments, we deliver coordinated designs that minimise operational disruption and programme risk. Our team works closely with multidisciplinary stakeholders to manage system interfaces, staged construction and temporary works requirements. By combining engineering expertise with practical delivery insight, we help de-risk implementation and maintain network performance. The result is compliant, robust and future-ready electrification infrastructure aligned with evolving operational and capacity demands.
