For local traffic lines characterized by severe investment environment, there has been a growing demand for a low cost signal system featuring easy maintenance. To meet this demand, we have developed a train detection device by using microwave balise (COMBAT: computer and microwave balise aided train detection) which allows a low cost configuration. It features noncontact tracking train detection. This system is intended to take the place of the conventional track circuit. This system detects the existence and direction of the train at the detecting point (microwave balise installation site). Use of this system has enabled logically continuous existing/nonexisting detection in units of the block configured with the detecting point as a boundary. Furthermore, whereas the conventional track circuit is restricted to track existing(0)/nonexisting (1) detection alone, the new system ensures highly reliable detection because it uses a train ID for train detection. Accordingly, the function of this system allows a train control system of a high degree of safety to be designed with a simple system configuration. A field monitor running test is currently under way to check the COMBAT performance to evaluate train detection performance using microwave balises and to verify the train detection logic. This paper introduces the COMBAT system configuration, microwave balise and concept of COMBAT train detection.
