朔州工务段管内的北同蒲线,是大秦线万吨、两万吨重载列车的主要装车基地,共有40多条运煤专用线,其中开通两万吨重载列车的专用线共8条,开通万吨重载列车的专用线共17条。近年来,大秦线煤运量的递增和万吨、两万吨重载列车的开行,加大了对线路设备的冲击。特别是道岔磨耗、几何尺寸变形等病害日益严重,成为了制约重载列车提速和运行安全的“咽喉”。面对严峻形势,朔州工务段从技术人员中选派精兵强 Shuozhou PTS Pipeline North Tongpu Line, is the main loading base of the 10,000-ton and 20,000-ton heavy-duty trains on the Daqin Line, with a total of more than 40 coal-only lines, of which 20,000-ton special lanes for heavy-haul trains 8, opened million tons of heavy-duty trains a total of 17 lines. In recent years, the increasing amount of coal transported on the Da-Qin Line and the opening of 10,000-ton and 20,000-ton heavy-haul trains have increased the impact on line equipment. In particular, turnout wear, deformation and other geometric dimensions of the growing disease has become a restriction of heavy haulage speed and operational safety “throat ”. Faced with the harsh situation, Shuozhou Public Works section selected from the technical staff to excel
