Development of a Technique to Predict Track Irregularity by Analyzing Frequently Obtained Data

The Technical Center at JR East is developing a “track monitoring device” to collect data frequently. Running tests are currently underway using a train in operation running on the Keihin-Tohoku Line. The authors tried to predict changes in track irregularity by analyzing acquired data. As a result, the authors became able to confirm detailed track irregularity by frequently obtained data. In addition, the authors were able to confirm the quantity of improvement after repair of the track. In this way the authors catch changes in track conditions and can judge the most suitable time for repair of the track. The authors are continuing with work in research and development to make the most suitable decision-making by the frequent accumulation of data.
