This paper describes the Safety Dialogue, a concept developed by the Finnish National Safety Authority (NSA) to support oversight and its work related to Safety Management Systems (SMS). The objectives of the Safety Dialogues as well as the method to perform them are described. After that the evaluation results based on the experiences of the participating organisations are included. The Safety Dialogue gives an opportunity to have deep going and informal dialogues between the safety authority and the railway actors on the safety issues, decreasing misunderstandings arousing from auditing and assessing. An important goal is to have an open discussion to improve safety performance and safety culture of the railway system.
