On December 8, as seven 5,000-ton heavy-haul freight trains achieved automatic decoupling and orderly entry into the south yard of Wanshuiquannan Railway Station on the Baotou-Shenmu Railway, a major breakthrough was made in the Research and Application of Heavy-Haul Train Grouped Operation Control System Technology, a national key scientific and technological project of China Energy Investment Group’s Top Ten Priority Initiatives. Jointly undertaken by China Shenhua Energy Company, the Baotou-Shenmu Railway, the CRSC Research & Design Institute Group and other entities, the project successfully realized the world’s first trial operation of a 35,000-metric-ton heavy-haul grouped train.
