eLTE Solution Helps Trains Haul More

Constructed the by Shenhua Corporation, the world’s largest coal supplier and a Fortune 500 company, the 345 mile (588 km) Shuohuang Railway is the longest heavy haul railway constructed by Shenhua. The railway is required to increase annual transportation capacity to 350 million tons. A single train needs to increase from 5,000 to 20,000 tons.

Long, heavy haul trains need multiple-locomotive synchronization. Dynamic operation of locomotives is required for the controllable train tail to solve the longitudinal impulse problem and extend the communication distance between the master and slave locomotives to over 1.5 miles (2,500m).

The Huawei eLTE solution provides:

  • Wide coverage, short delay, and high bandwidth
  • A 1.8 GHz TD-LTE network to implement multiple-locomotive control over 20,000 ton trains
  • Extending transmission distance and reduced latency
  • Full redundancy to ensure 99.999% system availability
  • Dual-network coverage and multiple-priority Quality of Service (QoS) mechanisms for zero operational interruption
  • Whole-line dispatch and driver room video surveillance

The success of the Huawei eLTE solution is a major innovation in heavy haul railway communication.
