Making Tracks—Combining Data Sources in Support of Railway Fault Finding

In this paper we describe recent Swedish trials to combine different data sources to support fault finding on railway vehicles and in railway operations in Sweden. The background to the trials, trials aims, the conduct of the trials and the data sources used are described in brief. The results of the trials are described using several case studies. Practical limitations and constraints are discussed together with the ways in which these might be overcome. Finally, the paper describes the way in which it is hoped to apply such methods to support future railway fleet management and operations.
