The system may include a second power source configured to supply power to the communication system to communicate the signal from the first vehicle to the second vehicle, and a controller. The controller may obtain an operational parameter, and communicate the signal based on the operational parameter when the first power source supplies power to the communication system. The controller may be configured to communicate the signal utilizing the power from the second power source based on the operational parameter when the first power source does not supply power to the communication system.

A system and method are disclosed herein and relate to a communication network within a hyperloop bogie, wherein the communication network logically connects a plurality of power electronic units. A first power electronic unit may generate a network packet to be sent to a second power electronic unit. The first and second power electronic units may perform a vote to determine a voting result. The first and second power electronic units may substantially independently perform further action based on the voting result. The first and second power electronic units may determine the voting result prior to the conclusion of a critical timeframe beginning with the transmittal of the network packet and ending with the voting result being stored.

A vehicle control system includes a controller that detects a communication loss between a first vehicle and a second vehicle and/or a monitoring device in a vehicle system. The controller operationally restricts movement of the vehicle system based on the communication loss. The controller obtains or generates a transitional plan that designates operational settings for the first vehicle and/or the second vehicle based at least in part on a location of the first vehicle and/or the second vehicle. The controller selectively changes movement of the first vehicle and/or the second vehicle via the transitional plan to reduce a speed of the first vehicle and/or the second vehicle responsive to the communication loss being detected.

Railyard management system for managing, assembling, disassembling and validating train consists and monitoring railcars in the railyard. The system provides for the collection of data and the movement of data from lower processing levels to higher processing levels, where an inference engine draws inferences regarding the current state of railcars and train consists within the railyard. The inferences can be based on characteristics of a transmission signal received at their respective railcars, said railcars forming a train consist. The system can be used to track the location and orientation of railcars in the railyard and to validate order and orientation of assets in a train consist based on the characteristics of the transmission signal at said railcars.
