The aim of this study is to examine how two of Swedish Transport Administration- regions perceive the tutorial of actions that the Swedish Transport Administration published as a template. The study examines four reports that investigate problems in the transport system. The tutorial that the Swedish transport administration presented contains guidelines regarding investigations in the transport system. The reports investigate what the problem or the lack of safety depends on. The result from the report is solutions that will solve and meet the problem. The result of this study shows that both regions follow the tutorial of actions and fulfils all the guidelines and demands. The regions present overall similar content. Although, with the same guidelines the reports are different from each other. Differences regarding presentation and the constructions of the reports is clear. The guidelines could be developed with new clarifications. New clarifications should reduce own interpretations and pander the work with reports that investigate problems in the transport system. The solutions that the reports present in the result are relevant, realistic and according to the tutorial approved as solid solutions.
