Wayside Railway Switch and Crossing Monitoring Using Isolation Forest Anomaly Scores

Yang Zuo,
Praneeth Chandran,
Johan Odelius
et al.

Abstract: Railway switch and crossing (S&C) systems have complicated moving structures compared with regular rail. They require multiple components that vary in complexity. The complexity of railway S&C, together with the fact that they are discontinuous points of the system, makes them vulnerable to defects such as squats. A squat on the switching rail could potentially cause rail breakage and lead to catastrophic results, such as derailment. In this study, a method based on anomaly scoring was investigated to … Show more
