The article presents an approach to the assessment of the safety integrity level (SIL) of rail vehicle subassemblies, in accordance with the applicable railway standards PN-EN ISO 50126-1, PN-EN ISO 50126: 2 and PN-EN ISO 50129. Particular attention has been focused on the calculation procedure related to the determination of the Tolerable Hazard Rate (THR) and Tolerable Functional Failure Rate (TFFR) indicators in a situation where various reliability indicators have been declared for components of rail vehicles, such as MTTFD or B10D. In this case, the assessment of the safety integrity level (SIL) using the above-mentioned railway standards may be difficult and it becomes necessary to use additional standards for safety systems based on electronic components.
