We are now conducting the research and development toward the ICT-driven innovation of maintenance (Smart Maintenance). One of them is the development of overhead line equipment monitoring system, which enables reading condition data of the equipment from operating train. In this paper, to estimate this system, a communication test was conducted between the reader device on Multipurpose Experimental Train (MUE-Train) and the RFID tag with temperature sensors on the feeder connecting points and the RFID tag with displacement sensors on the Spring Tension Balancer (STB). As a result, the strike rate of communication was 99.2%. Further, we developed a portable reader for the purpose of collecting data from a train instead of the reader device on the train. Using the portable reader, we confirmed that the strike rate of communication test was 98.5%. The communication test was conducted from the driver's cab of operating train, because the system can be used in patrolling inspection on a train. By collecting condition data from various overhead line equipment through this system, detecting of signs of failure and predetermined repairing are enabled, and safety and stability transportation can be further improved. We try to challenge for the Condition-Based Maintenance (CBM) by applying this system.
