SINGLE LEAK DETECTION METHODS APPLIED TO A BRAKE PIPE MODEL
Whereas there exists a procedure for detecting presence of excessive leakage in a brakepipe, the methods employed in actually locating the leaks are still very crude. Such methods are invariably labor intensive and time consuming, requiring railway personnel to walk alongside the train to look for audible leaks either by the unaided ear, or sometimes with a sonic-meter. This paper proposes three methods of locating single-faults, all based on a limited number of pressure measurements (possibly localized at the front-end or the rear-end of the train).
