The invention relates to a method for monitoring the physical state of a longitudinal element (10) of a railway-type rail, the method comprising: - a step of detecting mechanical waves moving along the longitudinal element (10), in particular due to the passing of a train, by means of an array (14) of mechanical wave sensors placed along and in contact with the longitudinal element, the array (14) comprising at least one first pair (A) of sensors (1, 2) each positioned at one end of a first portion (10a) of the longitudinal element (10), and - a step of processing the signals emitted by the sensors (1, 2) in the array (12) of sensors, the processing step comprising the determination of at least one first interfered signal determined from signals provided by the sensors (1, 2) in the first pair (A) of sensors over a first predetermined period of time.
