Abstract
We present results of a fiber optic structural health monitoring (SHM) system on an operational passenger railroad in Hong Kong. The system is based on a network of FBG sensors that measure strain and temperature in a multitude of critical locations. The sensors are mounted on guiding rails as well as on the under-carriage of passenger cars, using specially packaged strain sensors. The system - which is fully operational and in present service use - is providing invaluable and timely information about stresses experienced during service, both static and dynamic, under different operational conditions. The sensors also provide information on the loading and traffic status of the passenger cars; temperature-induced stresses and deformations on rails and carriages; temperatures in and around axles and wheel brakes; dynamic axle vibrations due to corrosion and bearing wear; and other parameters relevant to railroad health monitoring.
