西煤东运“大动脉”！大秦铁路货运量破九十亿吨

Core Insights - The Daqin Railway has achieved a cumulative freight volume of over 9 billion tons, marking its significance as China's first heavy-haul railway and the largest single railway in terms of freight volume [1][3]. Group 1: Historical Context and Development - The Daqin Railway, spanning 653 kilometers, was opened in 1992 with an initial annual freight volume of only 42.6 million tons, which has now stabilized at around 400 million tons per year, with a capacity of 450 million tons annually [3]. - The railway plays a crucial role in transporting coal from the resource-rich regions in the west to the energy-hungry coastal areas, thus alleviating energy bottlenecks and supporting economic growth [2][3]. Group 2: Operational Efficiency and Innovations - The Daqin Railway has developed a comprehensive heavy-haul transportation system characterized by "production-transportation-demand" alignment, "collection and distribution" coordination, and "speed, density, and weight" integration, which has been successfully applied to other railways [4][5]. - Technological advancements have enhanced operational efficiency, including dynamic monitoring of vehicle status and the implementation of intelligent scheduling systems that reduce human error [5]. Group 3: Environmental Impact - The Daqin Railway's operations have resulted in significant environmental benefits, including the conservation of approximately 99 million tons of standard coal and a reduction of 240 million tons of carbon dioxide emissions, highlighting its contribution to energy security and environmental protection [5].
