A computer-implemented method for detecting a fault in an electromechanical system in a railway infrastructure, the method comprising receiving electrical usage data indicative of the value of an electrical usage parameter associated with the electromechanical system; receiving temperature measurement data indicative of the present temperature of the electromechanical system; determining, based on a predetermined relationship between the electrical usage parameter and the temperature, whether or not the value of the electrical usage parameter is indicative of a fault in the electromechanical system and if so, issuing an alert to indicate the presence of the fault. The electromechanical system may be a railway points system. The electrical usage parameter may be current, voltage, or power used by the system. The determining step may comprise using a linear correlation between the temperature and the current to determine a threshold value to which the current measurement is compared. |
