Recently, the Western Inner Mongolia to Central China Railway, the world’s longest heavy-haul railway built in one stage and China’s largest special line for coal transportation, has completed track laying, which will ensure its official operation on October 1, 2019.
With a total length of 1,837 kilometers, this line spans 7 provinces in China and it is another ultra-long coal transport corridor after the Datong-Qinhuangdao line. More than 30 companies were involved in the construction work, among which 13 subsidiary companies from China Railway Construction Corporation Limited undertook the construction of 19 bid sections.
In order to construct the line efficiently and in high quality, China Railway 19th Bureau Group chose Type-CPG500 track layer, which is characterized by high degree of automation, good laying quality and simple operation. Type- IIFC16 sleeper, featured by convenient installation and maintenance, was introduced by China Railway 11th Bureau Group for the first time to ensure the quality of the line and the safety of track laying.
Besides, steel rails for this line were weld printed to make it lifelong-traceable for the welding quality of each rail. A railway dispatching safety information management system was also set up, which not only ensured construction safety but also improved the dispatch command capacity and construction-production efficiency.
Western Inner Mongolia to Central China Railway connects Inner Mongolia, Shaanxi, Gansu and Ningxia, the so-called "Golden Triangle" Energy Area and runs through the urban agglomeration in the middle reaches of the Yangtze River. Connecting a number of coal collecting and distributing lines, it is a new transport corridor in response to China's national strategy of north-south coal transportation.
