	Technical committee on Condition Monitoring and Preliminary Diagnosis Technology for Railway
	The progress of sensor device, data communication and AI computer has been realizing automatic monitoring and preliminary diagnosis for equipment/system. Regarding railway system, labor saving of maintenance management by these technologies begins to come true. It is important that monitoring and preliminary diagnosis are in harmony with between subsystems as well as development of monitoring technology and preliminary diagnosis technology. This report describes domestic and foreign findings concerning the current situation and needs of condition monitoring technology and preliminary diagnosis technology of each field of railway, and gathered the condition monitoring system of other industry in Japan. And it describes investigation results on point of view of practical use possibility of condition monitoring technology and preliminary diagnosis for railway, furthermore writes up outlook of railway system which have sophisticated maintenance technology and achieve maintenance laborsaving and reduce the cost with ensure railway safety.
