Abstract: The disclosure relates to a light train control system applied to oversea freight railways. The system integrates automatic block, station turnout control and train operation overspeed protection control and comprises an on-board subsystem, an RBC subsystem and a satellite positioning differential base station management subsystem, wherein the on-board subsystem is respectively connected to the RBC subsystem and the satellite positioning differential base station management subsystem. The light train control system adopts two-way continuous train-ground wireless communication and uses on-board signals as main signals of train operation to control the train operation; meanwhile, the system monitors the train operation, so as to provide an alarm to a driver when the situation changes, and to brake a train when necessary; and the system uses an electronic map to manage line data of a whole line, achieves dynamic configuration of the transport capacity by means of a virtual block technology, and remotely controls basic signaling equipment by means of an RBC. Compared with the prior art, the disclosure has the advantages of efficient system operation and simplified trackside equipment.
