Concord Control Systems (CCSL), a leading manufacturer of embedded electronics and critical rail solutions, has developed India’s first fully indigenous zero-emission propulsion system for diesel locomotive conversion. Built entirely in India, the system marks a milestone in advancing the nation’s drive towards net-zero emissions and complete railway electrification by 2030. 

  

Powered by Lithium Iron Phosphate (LFP) batteries with a DC chopper-based drive, the system operates only when required, eliminating idle fuel use, boosting efficiency, and achieving zero emissions. Except for a few semiconductor devices, every key component—from chopper and Vehicle Control Unit to sensors, controllers, and driver displays—has been designed and manufactured by CCSL. 

“This propulsion system is proof that India can lead in next-generation rail technology. With this achievement, we have set a reference point that will guide the industry towards sustainable, cost-efficient, and self-reliant solutions,” said Sadasivan V., Principal Executive Director, Advanced Rail. 

“This development is a proud moment not only for Concord but for India’s innovation ecosystem as a whole. By delivering the country’s first 100 per cent indigenous Zero Emission Propulsion System, we are advancing the twin goals of sustainable mobility and self-reliance, while supporting Indian Railways’ target of achieving 100% electrification by 2030,” said Nitin Jain, Joint Managing Director, Concord Control Systems. 

The propulsion system, retrofitted on a 700 HP diesel-electric platform, delivers 800A peak current to traction motors. It also integrates digital driver displays, CCTV/DVR monitoring, and a Remote Monitoring System for predictive maintenance and real-time diagnostics. 

By reducing idle losses, improving efficiency, and enhancing safety, the innovation sets new benchmarks for sustainable rail technology. It also provides a scalable solution for converting diesel locomotives into zero-emission platforms, reaffirming CCSL’s role in driving India’s self-reliant, world-class rail infrastructure.
