A device for detecting railway equipment defects, comprising at least three diagnostic modules mounted on a generic railway vehicle:



a first module (geometrical module) configured to measure at least a geometrical feature of the track;
a second module (acceleration module) configured to measure in at least a point of said vehicle the side and/or vertical accelerations transmitted from the track to said vehicle;
a third module (visual module) configured to acquire the images of the track elements and to analyze them to verify the presence of anomalies;

said modules being configured to associate with each detection carried out when the railway vehicle passes, on which they are mounted, the position where the detection was carried out and to calculate, for each detection, a severity index representative of the deviation of the detection with respect to the standard condition without defects.
