Fibre Bragg grating sensors for smart railway monitoring
A new approach for structural health and conditions monitoring of trains and railway tracks using fibre Bragg grating sensing networks will be described. Track borne fibre Bragg grating sensing networks are used to monitor moving trains whereas fibre Bragg grating sensing systems installed on passenger trains are used to monitor track condition as well as critical train components, including pantograph catenary interactions. This approach minimizes capital investment to monitor extensive railway networks for safety and maintenance purposes.
