Abstract (en)
Method for determining a direction of motion of a wheel of a passing train on a rail track, the method comprising:- sensing, in at least a first and a second direction different from the first direction, a change in a magnetic field value caused by stress exerted on the rail via the wheel of the passing train, wherein the magnetic field value is indicative for a change in a flux density of a magnetic field originating from the rail track, wherein the sensing comprises- obtaining a first signal associated with the wheel comprising a first plurality of the magnetic field values for the first direction for respective times from the magnetic field sensor, and- obtaining a second signal associated with the wheel comprising a second plurality of the magnetic field values for the second direction for respective times from the magnetic field sensor; and- determining the direction of motion of the passing wheel on the basis of the obtained first signal and second signal.
