Shared risks at interface between railway undertakings and infrastructure managers

Abstract

Organisational changes on European railways significantly affected the way how the railway transportation works. The state railways were divided and new entities came into market. The cooperation between the actors is to be managed with the help of mandatory safety management systems, based on risk management principles. In this paper, we propose a novel notation for describing ‘shared risks’, i.e. the hazards which sources, possible risk reduction measures and/or consequences are not covered by one safety management system. The standardised description of such hazards should improve understanding of their nature and thus make the application of risk reduction measures more effective.
