To establish the supplementary prescriptions and competences required in order to minimize the risks on a railway work site, especially when trains are circulating on the adjacent track (Note: the European Directive 92/57/CE for the safety and health prescriptions on temporary or mobile site works does not consider the specific railway problems). The requirements are:
-The list of railway risks;
-Common principles for the protection of fixed and mobile work sites with trains circulating on the adjacent track and working track;
-Common solutions and technology to be applied and their use;
-Qualification of the agents responsible for the work site protections.
