Shuo Huang Railway(SHR) Overview
SHR is owned by the Shen Hua Group , the world largest coal mine provider. SHR began operating in 2000 with 588km length SHR has carried 234 million tones of coals in 2012 SHR now are planning to increase the transport capacity to 350 million tones in the next 5 years.
Shuo Huang Railway Overview
SHR need to update its railway communication
infrastructure to reach the capacity increase target

The Future Target
Single train capacity should be up to 20000 tons
In the future
Single train capacity is 5000 tons
Now
200,000,000 tons
350,000,000 tons
Yearly transport capacity
900,000,000 USD

Challenges for Existing Communication System
More
Transport
Capacity
Frequency
QoS and
Security Service
The existing system couldn’t
provide QoS mechanism to
guarantee the robustness of
key communication
SHR needs more service such
as video surveillance and
trunking service .
SHR cannot achieve GSM-R
frequency that means SHR
cannot use GSM-R system to
replace the existing system
Outdated
System
The existing analog
communication system couldn’t
support multi-locomotives control
operation that will greatly limit the
transport capacity
