On April 23, China Shenhua, a subsidiary of China Energy Investment Corporation (CHN Energy), achieved a groundbreaking milestone in international heavy-haul rail transport through successful field testing of its cluster-based operation control system on the Baoshen North Line.

Two 5,000-ton unit trains demonstrated unprecedented performance with a 768-meter dynamic tracking interval and 186-meter precise in-station stopping distance, shattering the traditional 7-minute train tracking limit.

This three-year collaborative innovation with China Railway Signal & Communication (Group) Co., Ltd. (CRSC) employs a trinity control theory integrating absolute time, relative speed and dynamic positioning. The cluster coordination technology effectively resolves safety risks including coupler breakage and derailment in conventional long-haul trains. Test results show the system reduces dispatch intervals to 3.5 minutes for 5,000-ton trains and 5 minutes for 10,000-ton configurations, significantly enhancing line throughput.

As one of CHN Energy's top ten key scientific projects, this breakthrough establishes global leadership in heavy-haul railway technology. Shenhua plans to conduct full-scenario trials with seven trains totaling 35,000 tons within the year, further validating system capabilities for operational deployment.
