Distributed Acoustic Sensing – innovative data for railway infrastructure?
Infrastructure managers deploy several different systems and sensors to monitor and manage their assets and rolling stock. Wayside Train Monitoring Systems and Check Points are used to acquire the load status of vehicles, to detect derailments and furthermore, they measure deviations from an ideally round wheel and can, as a result, detect flat wheels. As switches and turnouts are a crucial part of a railway infrastructure, monitoring their condition is relentless. Beside manual inspections, sensors are assembled on switches and turnouts to derive condition of these assets and furthermore, the track-recording vehicle measures the entire net up to four times a year and delivers data such as longitudinal level, gauge, inclination and other.
This presentation seeks to describe the effort of existing trackside fibre optic cables, originally used for signalling and telecommunication, to monitor track and train condition. By recording passing trains, it is not only possible to determine train condition; it also provides information about track condition and its assets.
Ivan Vidovic is working as a research associate at the Institute of Railway Engineering and Transport Economy at Graz University of Technology in Austria. He studied Civil Engineering Sciences with Environment and Construction Management and graduated in 2016. In his research, he deals with innovative data analyses, track access charges and wheel-rail interaction. Additionally, he examines the potential of fiber optic sensing in railway asset management.
