Understanding the risk of level crossing derailments

One of the biggest remaining safety risks to rail operations in many countries is posed by level crossings. In order to help prioritize investment in the upgrading or removal of crossings, it is important to develop a tool to identify the potential risk of train derailments. A crossing derailment prediction model has been developed, for which it is necessary to understand the chain of events leading to a given consequence and identify the probability of each event occurring. The impact of faster train speeds is an area of concern, and with limited funds available to spend on upgrading level crossings, targeted improvements need to be made. It is suggested that combining the level crossing models and models for other risks into a systems-wide analysis tool would be beneficial to the rail industry as a whole, as well as to surrounding communities so that they can create better risk mitigation strategies. This in turn would provide a tool to aid in decision making regarding infrastructure improvements and the allocation of limited funds available.
