The paper is concerned with the developments of risk analysis during the last decade, starting from full range quantitative risk analysis of e.g. a level crossing based on the CENELEC standards EN50126 and EN50129 up to semi-quantitative methods for risk analysis. To expedite this shift from pure quantitative approaches to a more categorized approach were the perennial challenges of insufficient availability of accurate data and the sheer complexity of the reality to be model quantitatively. The article contains both a presentation of a complete quantitative risk analysis for a level crossing as well as a discussion of the crucial points that will need improvement on the basis of a new semi-quantitative standard for risk analysis that has been issued as a national pre-standard in Germany. The relation to the current regulations stipulated by the European Railway Agency and recent publications on this issue are presented as well.
