Conference paper


In the assessment of safety aspects for the Gardermobanen railway signalling system, the methods indicated in the CENELEC Railway safety norms were utilised. The safety documentation was presented as Safety Cases that were assessed. During the development and engineering period, a proactive way of working was used by the Assessor, to disseminate understanding of the Assessor's point of view as early in the process as possible. Thus, the Assessor's sources of information were taken from the development process, the system descriptions as well as early drafts of the Safety Cases.
