Conceptual feasibility of using FBG sensors for train detection function has been established through research and field trials conducted by the Hong Kong Polytechnic University in collaboration with the Kowloon-Canton Railway Corporation. A stringent development process is required to commercialise the product which would have many advantages over conventional means of train detection. The Hong Kong Polytechnic University together with the two railway corporations have started on the development process and exploration of further applications of FBG sensors in the railway.
