Abstract

For diagnosing a railroad switch with a point machine, a first and a second time series (TS1, TS2) of a sensor signal (SS) of the point machine are received. Moreover, changes (CH) in the first and the second time series (TS1, TS2) are detected indicating changes of operational conditions of the point machine (PM). Furthermore, an event point (E1-E4) of a respective change (CH) in the first and in the second time series (TS1, TS2) is allocated to a respective component of the railroad switch (SW) or of the point machine based on a simulation modelling the respective component. Then for a respective component:- event points (E1-E4) allocated to that respective component (C1) are identified,- the sensor signal (SS) at a first identified event point (E1-E4) in the first time series (TS1) is compared with the sensor signal (SS) at a second identified event point (E1-E4) in the second time series (TS2), and- depending on the comparison a component-specific fault information and an identification of the respective component are output.
