Hyundai Rotem finds faster track to carbon neutrality with high-speed rail

Hyundai Rotem, the rail manufacturing arm of Hyundai Motor Group, has developed a software platform designed to reduce energy use across high-speed rail networks, the company said Friday. Developed in partnership with Korea Railroad Corporation and Korea National University of Transportation, the Intelligent Energy-Efficient Operation System (IEOS) analyzes real-time track conditions and environmental data to calculate the most efficient speed for each segment of a journey, minimizing the acceleration and braking that drive up energy consumption. On a pilot run on the KTX-Eum line between Seoul and Gangneung, the system reduced energy use by as much as 12.2 percent. The push for efficiency comes as rail operators globally face mounting pressure to curb emissions without expanding already costly infrastructure. High-speed rail is often promoted as a lower-carbon alternative to air travel, but energy use remains significant, particularly on routes with frequent speed changes. Software-based solutions like IEOS are gaining traction as a faster, less capital-intensive way to deliver emissio
