The aim of this paper is to describe an ongoing project with the aim of improving safety in an organization working with maintenance and development of the railway infrastructure in Sweden. The first sub goal was to investigate the General Failure Types in the organization. Seminars and interviews, based on the Tripod Delta method, with 62 employees resulted in a description of these latent errors in the organization. Recommendations for an improvement toward a safety culture was suggested, action plans were formulated and, in some cases, implemented. A follow up study is planned in a two year perspective.
