A track switching arrangement for a track-based guided transportation system, wherein the track switching arrangement forms diverging pathways and enables vehicle-side switching of a vehicle in the guided transportation system. The track switching arrangement includes an upstream pathway; two downstream pathways; and a path switching transition region having the diverging pathways between the upstream pathway and the two downstream pathways. Each of the pathways includes track elements configured to interact with one or more respective bearings of the vehicle to provide levitation to the vehicle and/or guidance for the vehicle.

A method for displaying secondary signal devices for a driver of a railway vehicle during a journey by a railway vehicle. From a current vehicle position of the railway vehicle and an already known signal position of a secondary signal device, an actual distance of the railway vehicle in relation to the secondary signal device is determined. In the case that the actual distance is not reached in respect of a predefined current warning distance of the railway vehicle relative to the secondary signal device, a proximity of the railway vehicle relative to the secondary signal device is displayed to the driver.

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.

A system and method for virtual block stick circuits is presented. The present disclosure implements specialized algorithms adapted to determine the true status of a virtual block based on multiple inputs from different perspectives. In one embodiment, the system can use the far house perspective of that virtual track segment and the PTC hazard for the near virtual track segment directly adjacent to the near house uses the near house perspective of that virtual track segment. For the middle virtual track segments, the near house perspectives of the middle virtual track segments are held ‘TRUE’ if they are already ‘TRUE’ when the train first enters the block, using stick circuits for the near house perspective of the middle track circuits. The vital application can then indicate the true state of the virtual track segment as occupied (FALSE), to protect the train from trains that follow.

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.
