The invention relates to a method for identifying the characteristics of a rail vehicle (FZ), in which an axle counter (AZ1 ... AZ2) records measurement data during the passage of the rail vehicle (FZ). The measurement data is analyzed by a computer to determine the axle spacing of the rail vehicle (FZ). Based on the determined axle spacing, a first characteristic is determined by the computer, namely whether the rail vehicle (FZ) is a passenger train or a freight train. In a first test step, the determination of this first characteristic is checked to see if identical or similar patterns can be found in at least a predominant part of the sequence of axle spacings. If no pattern can be found, the rail vehicle (FZ) is assigned the characteristic of a freight train as its first attribute.Once a pattern has been identified, the railway vehicle (FZ) is assigned the characteristic of a passenger train as its first property, and / or a further test step is carried out to validate or extend the test result. This process can be supported by machine learning. Furthermore, the invention comprises a device for determining the properties of railway vehicles (FZ), a computer program, and a delivery device.
