H‑Infinity designs electrical systems for railway and transit infrastructure — traction power substations, catenary systems, SCADA integration, and station power distribution.
Railway electrification requires specialised electrical engineering that addresses the unique challenges of moving loads, harsh outdoor environments, and critical safety requirements. From traction power substations that convert grid power to railway-specific voltages, to catenary systems that deliver power to passing trains, to SCADA networks that monitor and control the entire power infrastructure — our team delivers integrated electrical solutions that keep rail systems running safely, reliably, and efficiently. We serve metro systems, heavy rail, light rail, and high-speed rail projects.
Design of railway traction power substations (TPSS) — AC and DC systems, rectifier stations, catenary supply, and sectionalising posts along rail corridors.
Electrical design for overhead catenary systems (OCS) — contact wire sizing, sectioning insulators, bonding and earthing, and power supply optimization for electric trains.
Remote SCADA systems for railway power infrastructure — real-time monitoring of substations, fault detection, remote control of disconnect switches, and predictive maintenance.
Electrical power distribution for railway stations and depots — platform lighting, HVAC, ticketing systems, passenger information displays, and building management.
Specialised protection schemes for traction networks — earth fault detection, arcing fault protection, selective tripping, and coordination with grid upstream protection.
Harmonic analysis and power quality assessment for railway electrification — impact studies on utility grid, flicker analysis, and mitigation for traction loads.
Power flow and short circuit studies for railway electrification projects — load forecasting, substation spacing, regenerative braking recovery, and grid connection studies.
Pre-commissioning and acceptance testing for railway electrical systems — traction substation testing, catenary integrity checks, SCADA integration tests, and system commissioning.
Our team of power systems engineers is ready to provide expert guidance, detailed studies, and robust solutions tailored to your specific requirements.
