Distributed bogie diagnostics for track monitoring

A method of monitoring a track using train cars includes collecting first sensor data corresponding to a track location by a first sensor network on a first train car. Based on the first sensor data, a potential track anomaly at the track location is identified by a diagnostics system on the first train car. A message describing the anomaly is transmitted to diagnostics systems located on other train cars. The message is received by a second diagnostics system on a second train car located behind the first train car. The second diagnostics system determines a time at which the second train car will be passing over track location and, at the determined time, collects second sensor data. If the track anomaly is present in both the first sensor data and the second sensor data at the track location, a train control system is notified of the track anomaly.

Automatic train stop control system

A method controls a movement of a train to a stop at a stopping position between a first position and a second position. The method determines constraints of a velocity of the train with respect to a position of the train forming a feasible area for a state of the train during the movement, such that an upper curve bounding the feasible area has a zero velocity only at the second position, and a lower curve bounding the feasible region has a zero velocity only at the first position. Next, the method controls the movement of the train subject to the constraints.
