In a method for monitoring the condition of rail switch points and for detection of premature abrasive wear-and-tear in the region of the tongue switching rail (3) of the points, the signals from at least one proximity sensor (2) in the region of the tongue switching rail (3) of the points during the time of travelling over them are evaluated, in which case the smallest measured value ofthe separation distance (1) during the travel is stored in memory, the alteration of the smallest measured value, as well as at least a first limiting value for the smallest separation distance are compared with one another and in that, when this first limiting value is exceeded, a warning signal is generated.

Dans une méthode visant à contrôler l'état des pointes d'aiguille de rail et à déceler l'usure par abrasion prématurée dans la zone de la lame d'aiguille (3) des pointes, les signaux d'au moins un capteur de proximité (2) dans la zone de la lame d'aiguille (3) des pointes sont évalués pendant la durée du déplacement au-dessus des pointes, auquel cas la plus petite valeur mesurée de la distance (1) d'écartement pendant le déplacement est mise en mémoire, la modification de la plus petite valeur mesurée, ainsi qu'au moins une première valeur limite pour la plus petite distance d'écartement sont comparées l'une avec l'autre, et lorsque cette première valeur limite est dépassée, un signal d'avertissement est produit.
