A system may include a sensor that detects positioning data indicative of a position of a first coupler of a first vehicle system and positioning data indicative of a position of a second coupler of a second vehicle system during a coupling event of the vehicle systems. A controller includes one or more processors that receive the positioning data of the first and second couplers and determines whether the first coupler is misaligned with the second coupler. The controller may initiate an action of the first coupler, the second coupler, the first vehicle system, or the second vehicle system to change a position of the first coupler, the second coupler, the first vehicle system, or the second vehicle system. Changing the position of the first coupler, the second coupler, the first vehicle system, or the second vehicle system aligns the first coupler with the second coupler.

Device, system, and method for monitoring a distance between rail cars during coupling

A system may include a controller with one or more processors. The controller may determine the wheel size of a wheel of a vehicle during a trip. The one or more processors may communicate a message associated with the wheel size to an off-board device when the wheel size is below a threshold size.

System and method for controlling an axle of a vehicle

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

A system and a method include an onboard communication system configured to be disposed onboard a vehicle system and comprising one or more processors. The one or more processors may generate a session key that includes a shared secret key that is known by the onboard communication system and an off-board communication system, generate one or more encryption keys by hashing the session key with an identifier based on a cycle time that is known by the onboard communication system and the off-board communication system, generate one or more encrypted messages by encrypting one or more messages associated with one or more of the vehicle system or a route over which the vehicle system moves based on the one or more encryption keys, and communicate the one or more encrypted messages from the onboard communication system to the off-board communication system.

Communication system and method

A vehicle control system receives a proximity signal at a sensor assembly from a vehicle system. The proximity signal indicates that the vehicle system is approaching a location of the sensor assembly. A sensor of the sensor assembly is activated responsive to receiving the proximity signal. One or more characteristics of the vehicle system are sensed as the vehicle system moves by the sensor assembly. A sensor signal that represents the one or more characteristics of the vehicle system is communicated to an onboard controller of the vehicle system and/or an off-board system to control operation of the vehicle system based on the one or more characteristics of the vehicle system.

Vehicle control system

A system and method determine that a vehicle system is beginning rearward movement based on one or more characteristics of the vehicle system that are monitored by a movement sensor. A warning device is controlled to sound a notification to one or more locations off-board the vehicle system. The warning device is prevented from controlling the warning device to generate the notification while the vehicle system is moving in a direction other than the rearward movement. The warning device is permitted to generate the notification responsive to determining that the vehicle system is beginning the rearward movement.
