Abstract
A method to facilitate reducing delays in braking applications in a train using a system. The system includes at least one computer for executing brake control functions of the train and a brake pipe that extends along a length of the train for supplying air for brake operations. The train includes a lead locomotive, at least one remote locomotive, and at least one railcar. The method includes sensing a change in airflow in the brake pipe, determining whether the change in air flow is desired, sensing brake pipe pressure, and filtering undesired fluctuations in brake pipe pressure during brake applications based on the determination of whether a change in airflow is desired.
