The crack growth in the first stage is fracture mechanically analyzed by means of two-dimensional modelling. The simulation results are assessed for the use of rail grinding. A criterion for the change of the crack growth direction could not be derived, but the following stages of the crack growth in the transverse direction and the final fracture and the conditions for secondary fractures are considered.
