Abstract: A sensing system includes a leading sensor, a trailing sensor, and a route examining unit. The leading sensor is onboard a first vehicle of a vehicle system that is traveling along a route. The leading sensor measures first characteristics of the route as the vehicle system moves along the route. The trailing sensor is disposed onboard a second vehicle of the vehicle system. The trailing sensor measures second characteristics of the route as the vehicle system moves along the route. The route examining unit is disposed onboard the vehicle system and receives the first characteristics of the route and the second characteristics of the route to compare the first characteristics with the second characteristics. The route examining unit also identifies a segment of the route as being damaged based on a comparison of the first characteristics with the second characteristics.

Abstract: A method for controlling a vehicle system includes determining a vehicle reference speed using an off-board-based input speed and an onboard-based input speed. The off-board-based input speed is representative of a moving speed of the vehicle system and is determined from data received from an off-board device. The onboard-based input speed is representative of the moving speed of the vehicle system and is determined from data obtained from an onboard device. The method includes using the vehicle reference speed to at least one of measure wheel creep for one or more wheels of the vehicle system or control at least one of torques applied by or rotational speeds of one or more motors of the vehicle system.

Abstract: A locomotive air brake control system that responds to penalty braking requests from external systems by applying a varying amount of train brake level based on monitored and calculated parameters in order to enforce a defined train condition. The system may include a minimum acceptable train braking, a condition to be achieved to prevent further application of train brakes, and a maximum train brake level to be applied in response to the request. Alternatively, the system may apply braking in stepped levels according defined thresholds for a train behavior variable of interest such as speed or deceleration. The system may be configured to incrementally apply and release train brakes during the adaptive penalty, and may also adjust the level of braking according to calculated braking capacity of the train.

Abstract: The present disclosure relates to an apparatus for warning of exceeding speed limit in railway vehicles, wherein a train speed is estimated after a predetermined time, a remaining time is calculated until a train reaches a speed limit based on the estimated speed, and when the calculated time is smaller than a preset reference value, a warning signal is generated. Thus, an adequate warning can be given to cater to a train operation situation because a TTSLC indicator is used that notifies when an emergency braking will be activated by exceeding a set speed limit value after a certain time lapses, resultantly increasing the train operation frequency and the availability of trains.
