Abstract
An on-board train brake safety monitoring and fault action system that compares actual train brake power with expected train brake power to provide real time reporting to the train driver of the margin between the actual brake power and a safe threshold. The system may be configured to automatically make a full service brake penalty if the actual brake system power is less than a safe brake power threshold, such as those required by government regulations, or to adjust the braking system to improve actual brake efficiency. The on-board train brake monitoring system may optionally receive data from wayside hot and cold wheel detector systems to augment the actual brake power measurements.
