When the Balise(the device to transmit information between the on-board equipment and the wayside equipment) failure occurs it may not be able to transmit data(Telegram) required for the train running. And in some cases it may be able to cause an accident. Therefore both the Balise failure affecting train safety running and the hazard in accordance with Balise failure require some activities to establish them. General failure mode & hazard analysis associated with the Balise are described in UNISIG SUBSET-036 spec & UNISIG SUBSET-088 spec. And with reference to these specifications safety activities are being performed. In recent domestic railway the train control system applying ETCS(European Train Control System) Level 1 2 is being serviced and is being planned and as part of this system the Balise is being applied. The design-method of the Balise device for each manufacturer are different therefore the Balise failure mode & failure rate are different either. But the functionalities & transmission-data format(Telegram) of the Balise in ETCS Level 1 2 application for each manufacturer are identical. Accordingly the hazard caused by function-fail can be identical either. In order to establish these hazard in this paper we analyzed the detailed functions of the Balise. And we analyzed the Balise failure types & failure effects in accordance with the detailed functions.
