This paper deals with the forming of stray currents in industrial spurs, stabling tracks and special purpose tracks near DC-electrified tracks. It describes methods which can be used to identify failures that lead to the occurrence of stray currents. Some innovative measuring methods are also introduced, all of them are based on results and knowledge obtained by practical experiments. The data and measurement results used in this paper come from measurements performed in the Bohumín railway station depot. It was found out that at this railway station, traction current leaked into the lightning control system. The method that was used in tracing these parasitic current paths, as well as the failures which led to the occurrence of these currents, are described in this paper.
