The invention relates to an axle counting method for rail-bound vehicles, having the following method steps: • coupling light into at least one sensor fiber (SF, SF1, SF2), the sensor fiber (SF, SF1, SF2) comprising at least one fiber Bragg grating (FBG1, FBG2) mounted on a rail (T), wherein each fiber Bragg grating (FBG1, FBG2) has a reflection spectrum with a reflection peak (P1, P2) at a Bragg wavelength (λ1, λ2) with a half-value width (FWHM), • generating a differential signal of two shear stress signals by detecting and filtering the time intensity curve of the light power reflected through the two mutually spaced fiber Bragg gratings (FBG1, FBG2, FBG2'), and • generating a wheel signal if the deferential signal exceeds a specified shear stress differential threshold.
