In fatigue load tests, unused Finnish concrete railway sleepers B97 and BP99 were loaded. The purpose of the loading tests was to analyse the fatigue properties of the sleepers and the effect of the fatigue on the stiffness of the sleeper. Furthermore, the significance of cracks was estimated in the study. The load levels were chosen so that it was possible to estimate the significance of the fatigue in a real operating situation. The fatigue limit that has been determined based on the loading tests and the calculatory limit state of crack formation are distinctly higher than the bending moments that have been measured in the field tests. Consequently, the deterioration of the railway sleepers under the traffic load and due to the fatigue is very unlikely.
