We have been conducting design safety evaluations of railway signalling systems, considering the consistency with international standards. On the other hand, in order to cope with the recent complexity of railway signalling systems, it is considered effective to utilize new evaluation methods proposed in recent years in addition to the conventional safety evaluation methods. In this paper, we report on a trial evaluation using STAMP (System Theoretic Accident Model and Processes) / STPA (STAMP based Process Analysis) as a new evaluation method.
