Track Condition Monitoring. The Sensonic Track Condition Monitoring (TCM) application delivers railroad operators and maintenance teams improves insight into the changing condition of their track assets. Vibration data from passing trains is gathered by lineside fiber optic cables to track performance changes.- Identify emerging faults quickly - every train generates data- Combine current and historical performance to trend and forecast performance- Optimise and prioritise maintenance activities. We listen to the vibration signature of track under every passing train to generate a digital SonicTwin® of the track asset. We use heat-maps to highlight areas of change and determine trends to enable more efficient track maintenance strategies.
