In an exemplary embodiment, a system includes a trainee operator control unit configured for wireless communication with a locomotive control unit for transmitting one or more commands to the locomotive control unit. A trainer is configured for wireless communication with the trainee operator control unit. The trainer is configured for monitoring the trainee operator control unit including the one or more commands transmitted from the trainee operator control unit to the locomotive control unit. The trainer is configured to transmit a brake application override command to the trainee operator control unit. And, the trainee operator control unit is configured to relay the brake application override command and/or a stop command to the locomotive control unit.

According to various aspects, exemplary embodiments are disclosed of systems, methods and devices related to remote control locomotive training. In an exemplary embodiment, a remote control locomotive training system includes a locomotive control unit coupled to a locomotive and configured to control operation of the locomotive, and a trainee operator control unit in wireless communication with the locomotive control unit. The trainee operator control unit includes a first wireless interface to transmit one or more commands to the locomotive control unit. The system also includes a trainer operator control unit in wireless communication with the trainee operator control unit via a second wireless interface. The trainer operator control unit is configured to monitor the trainee operator control unit by receiving messages from the trainee operator control unit indicative of the one or more commands transmitted from the trainee operator control unit to the locomotive control unit.

A method includes obtaining one or more images of a segment of a route from a camera while a vehicle is moving along the route. The segment of the route includes one or more guide lanes. The method also includes comparing, with one or more computer processors, the one or more images of the segment of the route with a benchmark visual profile of the route based at least in part on an overlay of the one or more images onto the benchmark visual profile or an overlay of the benchmark visual profile onto the one or more images. The one or more processors identify a misaligned segment of the route based on one or more differences between the one or more images and the benchmark visual profile and respond to the identification of the misaligned segment of the route by modifying an operating parameter of the vehicle.

A vehicle control system includes a controller to receive a current commanded speed, determine a current moving speed, and calculate a reference shaped speed to operate a propulsion system and/or a brake system to cause the current moving speed to approach the current commanded speed. The reference speed is based on a reference shaping model that changes the reference speed based on relative values of the current commanded speed, a previous commanded speed, the current moving speed, and a previous reference shaped speed. The controller controls the propulsion system and/or the brake system to cause the vehicle system to move at the calculated reference shaped speed. A method includes receiving a current commanded speed, determining a current moving speed, calculating a reference shaped speed, and controlling the one or more of the propulsion system or the brake system to cause the vehicle system to move at the reference shaped speed.

A wireless train control system includes: a device that generates a track circuit state signal indicating whether a track circuit is picked up or dropped and a time-triggered track circuit state signal indicating a drop at a timing delayed by a set time after the track circuit state signal indicates that the track circuit is dropped; and a controller that generates a stop limit point of a wireless-control-compliant train by using presence information if a preceding train is a wireless-control-compliant train, and generates the stop limit point by using the track circuit state signal and the time-triggered track circuit state signal if the preceding train is a non-wireless-control-compliant train. The controller does not update the stop limit point if the track circuit state signal indicates that the track circuit is dropped while the time-triggered track circuit state signal indicates that the track circuit is picked up.
