ABSTRACT: ENSCO Inc. in collaboration with Virginia Tech (VT) has developed, tested, and integrated a wavelet-based broken rail detection algorithm. This algorithm utilized acceleration data that was recorded by the Vehicle/Track Interaction (V/TI) Monitor, an autonomous measurement system that proved promising during an experimental blind test. To compliment the V/TI Monitor, a geo-fencing technology identified single axle impacts that occur at locations away from known track features.
