The paper considers the relation between ERA’s Safety Management System requirements and the new Safety Culture Model. The Finnish safety authority Traficom was interested in clarifying the relationship between the two models and identifying ways to include safety culture issues in Traficom’s supervision activities. A project to clarify the relation between the models was carried out during 2021. Project focused on safety culture in safety management systems of railway organizations, with a focus on the regulator’s role and possibilities to influence and assess safety culture. The main goal of was to produce information and tools to Traficom for its assessments of safety culture in the rail organisations. To accomplish the main goal, the project first clarified the relation between ERA SMS requirements and ERA safety culture model. An approach was proposed for the regulator to conduct three types of safety culture assessments. The project was a theoretical study and the approach as well as the methods that were developed needs to be tested empirically.
