Abstract
Railway switches are a crucial part of the railway infrastructure whose proper functioning is essential for safe and trouble-free rail traffic. The current consumption of a point motor responsible for a switch movement plays an important role in anomaly detection and predictive maintenance of a railway switch. The power consumed by point engines of railway switches depends on different factors, such as air temperature or humidity. This thesis presents various time series models that incorporate exogenous variables to model the total power consumed by railway switches. Those models enable the recognition of abnormal behaviour by railway switches to prevent failures through timely initiation of maintenance actions. iii
