Abstract
The safety of the railway system is guaranteed by the extremely high reliability of the technical systems. In fallback mode the human operator performs safety critical tasks to allow for a certain level of performance. Experience shows that errors by performing these tasks can cause significant damage. The paper describes how technical and non-technical measures were derived which alone or in combination make the railway system as a whole safer. To allow for a systematic evaluation, aspects like the applicable rules, performance shaping factors as well as the contribution to risk by specific failures are discussed and considered.
