The objective is to ascertain the causes and circumstances of the occurrence in cooperation with the victims, state and local government authorities, businesses, and organisations. The more important verbally obtained information is recorded and written information is stored within the document management system Delta. Railway undertakings retain all evidence and details of items, technical assemblies, documents, recordings of the data recording equipment and other information which might be important in determining the causes of the occurrence.
