EN provides guidelines similar to ENbut for the electronics systems used for signaling. CENELEC standards EN 50126, 50128 and 50129 provide guidance on RAMS (Reliability, Availability, Maintainability and Safety) for the rail industry, in Europe and further afield, with their use mandated by some TSIs. EN 50128, Safety Standards, Safety related Software, EN 50657, tool classification, SIL, CENELEC, TC 9X National Category Other Electrical Engineering, Electronic Engineering, Information Engineering Safety integrity level (SIL) is defined as a relative levels of risk-reduction provided by a safety function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a safety instrumented function (SIF). 04-25 the original version EN 50128:2001 has been replaced by the updated new version EN 50128:2011. The update is quite extensive and will effect many parts of the existing Railway systems. The aim of this study is to investigate the effect of the EN 50128 update.
