A method for monitoring a railway track (11) is provided, the method comprising detecting monitoring signals (MS) by a distributed acoustic sensor (10) being arranged along the track (11), where each monitoring signal (MS) comprises a monitoring signal value (MSV) for a first measurement segment (12) of the distributed acoustic sensor (10) and a monitoring signal value (MSV) for a second measurement segment (22) of the distributed acoustic sensor (10), determining a first event monitoring signal value (EV1) for the first measurement segment (12) from the monitoring signal values (MSV) that are detected during the passage of a rail vehicle over the position of the first measurement segment (12), determining a second event monitoring signal value (EV2) for the second measurement segment (22) from the monitoring signal values (MSV) that are detected during the passage of a rail vehicle over the position of the second measurement segment (22), and determining a difference value (DV) where the difference value (DV) relates to the difference between an average relative value (ARV) and a relative value (RV), where the relative value (RV) is given by the relative difference between the first event monitoring signal value (EV1) and the second event monitoring signal value (EV2), wherein the average relative value (ARV) relates to an average value of relative values (RV) determined from previous passages of rail vehicles. Furthermore, a monitoring system (15) for monitoring a railway track (11) is provided.
