Abstract:This report focuses on investigating the reliability of hotbox detection system and their measurement data in Dutch railway network. Then, to find the possible main factors which affect temperature result and give the solution correspondingly. The reliability of hotbox detection system is accessed by using root cause analysis (e.g. FTA & FEMA) and data analysis method (e.g. R&R study and reliability analysis). Furthermore, some possible reasons can be assumed based on the analysis result. Finally, possible solutions will be given according to the possible reasons. The analysis shows the HBD detection system has very good internal and external consistency in most of the time. However, abnormal data are generated in some case, most of the unreliability comes from repeatability. Based on this information, some possible main factors from parts variation, condition interference and alarm criteria setting have been found. And possible solutions are given correspondingly from three aspects.
