This paper presents a novel real-time tension monitoring method (RTMM), based on angular displacement of gear wheel and vibration of concrete weights, used to detect the service state of catenary without physical contact with the contact line. The classical detection of contact wire which relies on the inspection vehicle is not suitable for real-time monitoring. The method chooses the characteristic parameters which could reflect the tension of catenary with noncontact to determine whether the wire could still work normally or not. The paper also gets a test result which uses the new method to detect the tension of catenary. The result shows the method could monitor the catenary force safely and effectively.
