Abstract: A vehicle monitoring device includes a camera or other optical sensor configured to be disposed at a trailing end of a first vehicle system. The camera or other optical sensor is configured to output one or more images or video of a field of view behind the first vehicle system. The monitoring device also includes a controller configured to receive output from one or more sensors and to activate the camera or other optical sensor to output the one or more images or video based on the output from the one or more sensors. The output from the one or more sensors indicates one or more of a change in movement of the first vehicle system, a temperature, an acoustic sound, or movement of a second vehicle system.

Abstract: A remote initialization system and method for a vehicle system receive trip data for an upcoming trip at an off-board device. Using the off-board device, the trip data is communicated to the different back-office systems, and one or more of mandatory directives or software configuration requirements are received at the off-board device from the different back-office systems. An initialization data set that includes at least some of the trip data and at least some of the one or more of the mandatory directives or the software configuration requirements is communicated from the off-board device to an onboard controller of the vehicle system. The initialization data set is configured to be used by the onboard controller to control movement of the vehicle system in the different sets of the routes.

Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: A computer-implemented method is provided that includes obtaining a first secret and a first public key, and obtaining a second secret a second public key. The method may also include authenticating the first public key of the first vehicle based on a first private key associated with the first vehicle, and authenticating the second public key of the second vehicle based on a second private key associated with the second vehicle. The method may also include preventing a man-in-the-middle attack, by securing at least one of a first vehicle-to-central office communication, a central office-to-first vehicle communication, or a first vehicle-to-second vehicle, wherein the first vehicle-to-central office communication and the central office-to-first vehicle communication are authenticated based on a determined private key associated with a respective first vehicle on-board computer, and sending a message, with the central office server, to a vehicle associated with a conditional movement authority.

Abstract: A method may include detecting a first pressure and a second pressure of a fluid in a brake pipe of a vehicle system that includes a plurality of vehicles and extends from a lead vehicle to an end vehicle. The first pressure may be measured in the lead vehicle and the second pressure may be measured in the end vehicle. The method may further include determining a pressure differential signature between the first pressure and the second pressure and evaluating the pressure differential signature with a machine learning model to determine whether a blockage or a leak exists in the brake pipe. A system may include one or more processors configured to detect a first pressure and a second pressure of a fluid in a brake pipe. The one or more processors may be further configured to determine a pressure differential signature between the first pressure and the second pressure and evaluate the pressure differential signature with a machine learning model to determine whether a blockage exists in the brake pipe.

Abstract: A monitoring system includes a sensor that may output a sensed moving speed of a vehicle system. The monitoring system may also include one or more processors in communication with the sensor. The one or more processors may calculate a predicted speed of the vehicle system based on one or more forces acting on the vehicle system, and compare the predicted speed with the sensed moving speed. The one or more processors may also control movement of the vehicle system based on comparing the predicted speed with the sensed moving speed.

Abstract: A computer-implemented method of transforming movement authority limits for a train traveling in a track network, which includes determining authority of tracks associated with a switch, based at least partially on authority data and/or train authority data for the train, and providing authority on a switch leg of the switch based at least partially on the authority of the associated tracks. The computer-implemented method also includes determining authority of tracks associated with switches on at least two tracks, based at least partially on authority data and/or train authority data for the train, and providing authority on a crossover track between the at least two tracks based at least partially on the authority of the associated tracks.
