近日，我国成功完成3.5万吨级重载群组列车开行试验，标志着我国在重载铁路运输技术领域取得重大突破。此次试验在国家能源集团所属的朔黄铁路上进行，由多台大功率电力机车协同牵引，编组总长度超过4公里，总重达3.5万吨，创下国内重载列车重量新纪录。该试验不仅验证了重载列车在长大坡道、复杂地形条件下的安全运行能力，还实现了智能控制、同步操纵、故障诊断等关键技术的集成应用。3.5万吨级重载群组列车的成功运行，将显著提升我国西煤东运通道的运输效率，降低物流成本，对保障国家能源安全、推动绿色低碳运输具有重要意义。未来，相关技术有望在全国主要重载铁路线推广应用，进一步巩固我国在全球重载铁路领域的领先地位。
Recently, China successfully completed a trial run of a 35,000-ton heavy-haul multi-unit train, marking a major breakthrough in heavy-haul railway transportation technology. The test was conducted on the Shuohuang Railway, operated by China Energy Investment Corporation. Multiple high-power electric locomotives worked in tandem to haul a train over 4 kilometers long with a total weight of 35,000 tons—setting a new national record for heavy-haul trains. The trial not only verified the train’s safe operation on long gradients and complex terrains but also integrated key technologies such as intelligent control, synchronized traction, and real-time fault diagnostics. The successful operation of this ultra-heavy train significantly enhances the efficiency of China’s west-to-east coal transport corridor, reduces logistics costs, and supports national energy security and green, low-carbon transportation goals. These advancements are expected to be rolled out across major heavy-haul rail lines nationwide, further solidifying China’s global leadership in heavy-haul railway technology.
