Concord Control Systems Limited (CCSL), a manufacturer of electronics for railway applications, has developed an indigenous zero-emission propulsion system designed for retrofitting diesel locomotives. The system, powered by Lithium Iron Phosphate (LFP) batteries and a DC chopper-based drive, is intended to replace conventional diesel engines.
According to the company, the propulsion has been integrated on a 700 HP diesel-electric platform and delivers 800A peak current to traction motors. It includes features such as digital driver displays, CCTV/DVR monitoring, and a Remote Monitoring System (RMS) for predictive maintenance and real-time diagnostics.
Except for some semiconductor devices, the system’s key components—including the chopper, Vehicle Control Unit, driver display, sensors, and controllers—were designed and manufactured by Concord Control Systems. The company stated that the technology integrates high-voltage batteries with choppers, CAN-based Vehicle Control Units, and fibre-optic EMI-immune signal transmission.
“The 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 at 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% 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 of Concord Control Systems Limited.
Concord Control Systems Limited is a manufacturer of embedded electronics and critical electronic solutions for railway applications. The company is an RDSO-approved OEM and supplies advanced electrical and electronic systems to Indian Railways. Its portfolio includes systems designed for railway environments, with operations supported by R&D, testing, and manufacturing facilities.
