Abstract

This paper presents a methodology for assessing railway safety systems. This methodology is based on a SADT model of the system and on a probabilistic evaluation of each function and subfunction of this model. As an illustration, this methodology is applied to assess a specific railway protection system: the hot axle box protection system. Risks involved with a hot axle box are also presented. Finally, results obtained in the case of a high-speed rail line are analysed.
