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.

Systems and methods for detecting brake system anomalies

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.

Monitoring and communication device of a vehicle

System and method configured to determine a direction of movement of a vehicle in response to a brake being released or in response to initiating movement of the vehicle from a stopped position along a route. The direction of movement is determined based on a selected travel direction of the vehicle, a grade of the route, and at least one of applied tractive efforts or applied braking efforts.

Vehicle control system and method

The present invention relates to a system and method of providing communications for a mobile vehicle, comprising: a) providing the vehicle with the ability to communicate using a number of different communications methods; b) establishing a list of parameters, said list of parameters defining a set of criteria for determining the preferred attributes of the communications method to be used at any given time; and c) selecting a communications method based on said list of parameters.
