Abstract: In a system and method for detecting stray currents in an electric railway system track, at least one magnetic field sensor is provided, which is configured to sense values of a magnetic field parameter. The magnetic field sensor is moved along the track, and senses magnetic field parameter values at sensing locations along the track. The sensed magnetic field parameter values are processed to determine a condition of the track by comparing, for a portion of the current path comprising a first sensing location and a second sensing location different from the first sensing location, a first sensed magnetic field parameter value at the first sensing location with a second sensed magnetic field parameter value at the second sensing location, and if the first sensed magnetic field parameter value differs from the second sensed magnetic field parameter value by a predetermined amount, then marking the portion of the current path as a stray current portion. The magnetic field sensor is mounted on a vehicle configured for displacement along the track. A voltage is applied between a track rail and earth, for a current to flow through the track rail.
