Abstract

The article presents the FMEA method application, which is relevant in verification of design of two separated railway signalling systems. The efficiency of the method at the stage of the design was discussed. The method was identified as an important element of safety management process and as safety analysis method, which is included in the Safety Case and is applied for the sake of safety arguments and its assessment. Safety process management comprises several phases and appropriate actions, linked with each other in the way to create safety life cycle consistent with system life cycle. The safety case is a set of documents demonstrating that the product is compliant with defined safety requirements including analysis that indicates the correctness of the design and the correct reaction of the system to the failures, with appropriate and requested fail-safe reaction. It is necessary that railway signalling system should fulfil SIL4 requirement and remain safe in case of occurrence any kind of single failure of the equipment considered as possible.
