    Abstract: A system and method for providing a virtual approach signal restriction upgrade between physical signaling components is presented. In one embodiment, in a CTC type of operation, the use of a virtual signal with signal type functionality to split a block into two or more sections can allow a train currently governed by an approach indication to accelerate on a clear indication if the advance signal indication upgrades. The addition of audio frequency type circuits with the advance signal indication can allow a train to upgrade from a restricting indication to an approach or clear indication, while protecting open HT switches, broken rail, hazards, and follow up moves. The present invention provides a system for allowing trains to upgrade from a “restricting” indication to an “approach” or “clear and accelerate” indication with an upgraded PTC track line for the segment.

    Abstract: A vehicle warning system and method receive an information notification from a first vehicle system at a second vehicle system. The information notification includes traversal information associated with a position of the first vehicle system and/or an identifier associated with the first vehicle system. The information notification also including a warning that indicates of the second vehicle system is moving too close to the first vehicle system and/or the first vehicle system and the second vehicle system are headed toward an intersection. A decision is made as to whether a response should be sent based on the information notification and sending the response based on the information notification to the first vehicle system. The response includes a command to slow down or stop to avoid a collision with the first vehicle system.

    Abstract: An independent cart system with safety functions prevents unintended motion independently within different sections of the track while permitting motion along other sections of the track. A safety controller receives one or more input signals corresponding to operating conditions along the track. A safety program executing in the safety controller monitors the state of the input signals to determine whether a safety function is to be executed. When a safety program is executed, the safety controller transmits an output signal to one or more segment controllers present in one section along the track. Each segment controller is responsible for regulating current flow to the coils mounted to the corresponding track segment. In response to the signal from the safety controller, each segment controller in the section controls the power output to the coils along that section of track to achieve the safe operation desired in that segment.

    Abstract: A system and method for performing braking operations on a hyperloop pod are disclosed herein. The hyperloop pod may have a secondary braking system, wherein the secondary braking system may be operable to provide a first braking force. The hyperloop pod may have a transponder communication system and a line-of-sight system, wherein the line-of-sight system may be operable to detect a second hyperloop pod at a line-of-sight distance. The hyperloop pod may have a memory and a processor operable to detect a second hyperloop pod and determine a collision margin between the hyperloop pod and the second hyperloop pod. The hyperloop pod may engage the secondary braking system if a safety margin is equal to or greater than the collision margin.

    Abstract: A system and method for simulating positive train control (PTC) systems in a local and controlled environment using software and hardware. The system can simulate various functionalities of the PTC system in the environment using software and hardware components. The system can instruct the software of a train management computer (TMC) to control electromechanical valves to simulate air compression on brake pipes in response to the PTC system executing a penalty on the locomotive. The system can display statuses of various systems on the locomotive to a user using a cab display unit (CDU). The system can control the software and hardware components to simulate warnings and actions from the PTC system allowing locomotive engineers and conductors to experience the PTC system for optimum training.
