Hirect Completes Acceptance Testing for 6,000 HP Electric Locomotive Propulsion System
The Indian manufacturer also secured a development order from Indian Railways for four Mainline Electric Multiple Unit trainsets.
Indian power electronics manufacturer Hirect has completed the acceptance regime for its 6,000 hp (4,475 kW) electric locomotive propulsion system. The system was tested in a WAG-9 locomotive hauling loaded freight under severe duty cycles and a demanding thermal operating environment.
What Happened
Hirect designed, engineered, and manufactured the propulsion system in-house, including its liquid-cooled IGBT traction inverters, converters, and control software. According to the company, this qualification opens one of the world’s largest locomotive markets to its complete propulsion package and establishes a modular subsystem platform for new-build, retrofit, and hybrid locomotive programs internationally. In addition to the testing, Hirect secured a development order from Indian Railways’ Modern Coach Factory for complete propulsion systems for four Mainline Electric Multiple Unit (MEMU) trainsets. This 24-month program covers traction transformers, traction motors, and the fully integrated propulsion system, including the Train Control and Management System (TCMS).
Why It Matters
The completion of acceptance testing marks a significant step for Hirect as it expands its presence in the rail sector. The company describes the MEMU order as its first development order for a complete trainset propulsion system. Unlike traditional locomotives where traction equipment is concentrated in the engine, MEMU trains distribute traction equipment beneath the cars of the trainset. Hirect’s broader rail portfolio, which includes traction transformers, IGBT converters, auxiliary power supplies, SiC battery chargers, traction motors, and HVAC systems, supports the transition from diesel traction to hybrid, electric, and alternative-energy traction, including hydrogen.
The Bottom Line
Hirect has validated its in-house 6,000 hp propulsion system under rigorous conditions and secured a contract for four MEMU trainsets, positioning itself as a supplier of complete power and control systems for modern rail applications.
