A system and method for virtual block operational status control with long block time delay is presented. The present disclosure can advantageously increase the capacity and safety of the existing railroad track infrastructure used by the railroads by determining whether a virtual block is healthy or unhealthy. The long block mode can provide a coarse granularity on the presence of a train. In virtual block mode, the system can implement a finer granularity so the virtual aspects of the sub blocks can be realized. The present disclosure provides a long block mode that can provide the system an opportunity to analyze the potential tradeoffs between granularity and reliability by determining which mode (virtual block or long block) is best utilized in a given situation. The system can operate by default in long block mode and ignore the virtual block capabilities until absolutely needed.

A switch control method and apparatus, and a storage medium are provided, which relate to the field of urban rail transit technologies. The method includes: in a process that a train requests a target object for a switch resource, determining that the train is a train before and nearest a switch in combination with switch information sent from an object controller; when the switch is in an idle state, requesting the object controller to move the switch if it is determined that a current switch orientation of the switch is inconsistent with a switch orientation required by the train for the switch, so that the object controller controls to move the switch, and adjusts a status of the switch to a locked state after the switch is moved; and controlling the train to pass through the switch according to a response message returned by the object controller.

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.
