Shenhua Group Corporation is a mining and energy giant in China. As a Global Fortune 500 company, Shenhua Group is the largest coal-producing company in the world. Their Shuohuang Railway (SHR), with an operating route length of 594 kilometers, is a critical artery of China’s West-to-East Coal Transfer project. Shenhua hoped to expand the railway’s capacity to transfer 350 million tons of coal and needed to maintain efficient and safe operations of 20,000 ton capacity heavy-haul trains. The railway’s previous communications system could not support the expansion plan because of limited coverage distance and low reliability.
Huawei customized an eLTE solution that could meet the challenge. The wireless broadband system guarantees the communication between the master and slave locomotives located at both ends of trains, which could be up to 2500 meters apart. The eLTE network also enhances operational and maintenance efficiency with trunking dispatching, remote data acquisition, wireless video surveillance, data transmission and other services. It is the world's first LTE network for heavy-haul railways. It will allow them to continue to expand transfer capacity from 200 million to over 350 million tons of coal (leading to an increase of USD900 million in annual profits).
