Abstract

Much has been published on the locomotive and signalling system electromagnetic compatibility problem over the past decade and many solutions has been proposed. The problem can however only be solved optimally if a systems approach is taken. With this approach the railway system is viewed from a level where the locomotive and the signalling are components. The procedure described here starts by defining an acceptable risk for the railway system and then these requirements are allocated to individual components of the railway system, in a top down fashion. In order to ensure conformance to the allocated risk requirements, tests are performed under normal operating conditions and a failure mode effects and criticality analysis (FMECA) is performed for failure conditions, for each of the subsystems. Apart from the description of the pr
