ABSTRACT: The project „Neue Bahntechnik Paderborn“ (NBP) deals with the development of an innovative railroad concept. It envisions short autonomously guided shut-tles which are completely automated and even make decisions, for eg. starting only if there is a need. Fur-thermore the shuttles use the existing rails without differentiating between suburban and long-distance traffic. Thus the passengers needn’t change trains during their journey. Since the task implies a complex and dynamic process, an effective safety and failure management system (SFMS) must include the coactions of all possible factors. In addition, the dangers and threats must be identified and evaluated in the sense of security. This must be done uniformly for each single component of the system. An important aim of the SFMS is to keep the risk of a shuttle accident under employment of all justifiable means as low as possible. In a first prototype the individual sensores are simu-lated. This allows for the analysis of the effects of dif-ferent failures which can occur during the drive and the definition of processes which enable a fast remedy of the failure.
