The invention relates to a method for detecting wheel shapes of rail wheels with the aid of a measuring strip which consists of a row of measuring elements which are applied to the rails and which absorb the dynamic effects and which guide the corresponding electric signals of an electronic evaluation device for representing the wheel shapes. The signals are derived from the measuring elements, which displace the rails in the vertical direction and, preferably, in the transversal direction, and then an information array is formed in the evaluation device from the signals, which corresponds at least to the periphery of the wheel. The periodic signal of the shapes of the wheel is evaluated with the aid of a Fourier development.
