Train control system is the vital control equipment which is responsible for the operation of trains, and its functional safety must be validated through sufficient tests before actual use. Until now, most of them have gone through the interoperability testing stage with other devices by installing them at the railway site after performing validation on train control system developed by the simulator in a laboratory. In this process, more stringent validation on interoperability is required since interoperability for some cases is validated within the limited scope. This paper proposes a new interoperability test method and the tool to support it for the functional safety validation where the Ethernet and serial interface channel used by the actual train control systems are in common use.
