The working group has participated in bowtie risk analysis workshops, to understand the risks, identify control measures for those risks, and to evaluate the strength of each control. The bowtie diagram resulting from those workshops illustrates that work. A report on the bowtie risk analysis was published in November 2016. This report describes the working group’s analysis of the most effective measures to be taken to reduce the risk of freight derailments. It is accompanied by a set of appendices that contain details of the methodology for the workshops.
