Train and cargo dispatching make use of railway digital dispatching special communication system equipment to make up the network; the railway stations have digital dispatching special communication station subsystems, which connect with the main system of digital dispatching special communication via transmission network.
    4.无线通信系统
4. Wireless Communication System
本次设计采用450MHz B制式无线列调通信设备进行组网，通话方式为大三角方式，并设置无线列调监测系统。考虑到本线建成初期货运量较小，本着强本简末的铁路设计原则，本次设计暂不进行无线列调弱场区补强。
450MHz B system radio train dispatching communication equipment is used in this design to form the network; the call method is of big triangle method with radio train dispatching monitoring system. Considered the low cargo transporting quantity during early stage after construction, this design temporarily does not reinforce the feeble field of radio train dispatching with the railway design principle of strengthening the base and simplifying the least.

Track-side telephone loop line and sectional emergency loop line will be set within toll communication cable of this line. Track-side telephone consists of railway digital special communication system and communication polar in the section, which will be set with the interval of 1.5km.
（3）闭塞通道
 (3) Blocking passage
本线闭塞方式采用继电半自动闭塞，通道由长途电缆实回线提供。
The blocking method of this line is of all-relay semi-automatic blocking, in which the passage is provided by toll cable practical loop line.
6.车站（场）通信系统
6. Station (Yard) Communication System
（1）站场有线通信系统
 (1) Yard wire communication system
本次设计在各站的有线通信采用数字调度通信系统构成及车站值班员为中心的指挥系统。在车站值班员处设数字调度通信分系统值班台，将列调、站间行车、区间电话等区段通信回线以及信号值班等站内直通电话纳入值班台。
The wire communication in each stations of this design adapts digital dispatching communication system components and the command system centering the station duty person. There is digital dispatching communication subsystem duty board at the position of station duty person to introduce the station direct connection telephones and sectional communication loop lines such as train dispatching, travelling between stations and sectional telephones into duty board.
（2）站场无线及广播系统
 (2) Yard radio and broadcast system
本次设计在货运站设置无线平面调车系统，为本站从事调车作业的流动作业人员与固定作业人员之间、流动作业人员与流动作业人员之间提供服务。
There is radio flat dispatching system at the freight station in this design to provide services for communication between flowing workers of dispatching and fixed workers, and between flowing workers
