UIC 777-2:2002-09

This leaflet sets out recommendations for managing the risk from derailed trains near structures built over railway lines. It distinguishes between structures that are generally occupied (for example, multi-storey office blocks) and those that may not be occupied (for example, bridges). Different methods are proposed for these two types of structure. The methods take into account those people most at risk and the likely speed range for rail traffic passing under these structures. It is made clear that, in assessing the risk, some parameters are the responsibility of the railway and not the engineer.
