Abstract
Datong—Qinhuangdao line, as the first electrified double-track heavy-haul line dedicated to coal transportation in China, extends from Beitongpu line in the west,reaches Qinhuangdao in the east,and opened in Dec., 1992, totaling 653 km with designed volume of 1×108 t/a. In order to meet the requirements of national economical development, the transport capacity of the line must be expanded rapidly. Depending on independent innovation, MOR,for the first time in the world,realized the integration between GSM-R and Locotrol, the integration between 800 MHz digital radio and Locotrol, and the integration between a single set of Locotrol and SS4. Meanwhile, it developed auxiliary equipment for heavy-haul transportation through combining 2 Hexie heavy-duty locomotives with controllable train ends. Relying on integration innovation, it succeeded in operating 20 kt-level combined heavy-haul train on Datong—Qinhuangdao line, which triples the annual volume of the line from 1×108 t in 2002 to 3×108 t in 2007.
