A system (10) for detecting the presence of a rail end in a rail (18) of a railway track (20) includes a support structure (12) mountable to a component (14) of a rail vehicle (16). At least one magnetic field generator (22) is carried by the support structure (12) to generate a remanent magnetic field in the rail (18). A sensor arrangement (24) is carried by the support structure (12) in spaced relationship to the magnetic field generator (22) to detect magnetic flux leakage associated with the remanent magnetic field. The sensor arrangement (24) includes at least one pair of longitudinally spaced sensors, each sensor generating a measured signal based on the magnetic flux leakage detected by that sensor. A signal processing module (40) is responsive to the measured signals to calculate a differential signal from the measured signals of the sensors of the at least one pair of sensors. The differential signal is indicative of the presence of a rail end in the rail (18).
