A method (100, fig. 3) of warning a trackside worker 1 or personnel nearby a railway of the approach of a train 4 along a rail track 2. Initially, an acoustic signal S indicating the movement of a train along a rail track toward a trackside worker is detected (102, fig. 3) using a portable signal detector 3. Next, the signal is processed (104, fig. 3) to determine the speed s of the train and distance d2 from the trackside worker. If the speed of the train or the distance from the trackside worker exceeds a pre-determined threshold, then a wearable alarm 6 worn on the trackside worker is triggered (106, fig. 3) to warn the trackside worker of the approaching train. Also disclosed is a portable signal detector comprising a housing (7, fig. 4a), a sensor (9, 21, fig. 4a) and a processor (29, fig. 4b).
