Locomotive synchronization operation control（LSOC） is the ubiquitous and urgent key problem in heavy haul transportation. Recently, more and more researchers devote to the research of radio locomotive synchronization operation control. The new thinking of network radio locomotive synchronization operation control is put forward. Based on GSM-R, the components and structure of the network system, communication mode and particular functions of the OCU subsystem, AN subsystem, and network monitoring subsystem are expounded. The key technologies of safety data meeting, main-standby data link switching, multi-locomotive coordination and data processing and real-time network monitoring are presented. The network system breaks through limitation of the wireless digital transmission broadcasting station and resolves the problem of reliable communication in mountainous regions. Meanwhile, the technical specifications of two radio locomotive synchronization operation control systems are compared. Results of in-situ data transmission tests and integrated tests are provided.
