Railway Catenary Condition Monitoring: A Systematic Mapping of Recent Research.

In this paper, a different approach to the traditional literature review-literature systematic mapping-is adopted to summarize the progress in the recent research on railway catenary system condition monitoring in terms of aspects such as sensor categories, monitoring targets, and so forth. Importantly, the deep interconnections among these aspects are also investigated through systematic mapping. In addition, the authorship and publication trends are also examined.
