Various systems are used to monitor the technical conditions of railway lines and railway vehicles during operation. This contribution presents an optical fiber monitoring system based on a Fabry-Perot interferometer. The sensing optical fiber placed on the foot of the rail is elongated due to the bending of the rail during the passage of the train. The optimized signal demodulation algorithm allows determining not only the presence of a train in a particular area, the number of axles, and the speed of the train, but also some defects related to the technical conditions of railway vehicles. The detection method is shown in the passage of a passenger train consisting of a locomotive and four wagons moving at a speed of 98.08 km/h. The advantage of the system is the possibility to determine different useful parameters of train passage with the technical conditions of vehicles during normal operation.
