This paper describes approaches to the condition monitoring of suspension components in railway bogies developed at Politecnico di Milano, Dipartimento di Meccanica and their application to a high-speed rail vehicle. Two classes of FDI techniques are proposed and compared: model-free and model-based FDI. The two proposed FDI approaches were applied to the case of an ETR500 class high speed trailed car, and numerical experiments were carried out to assess their effectiveness. The next step of the research consists in the verification of the applicability of the methods to a real case and to this aim an experimental campaign was set-up on the high speed test train ETR 500-Y1 running on the Italian high speed railway network. The paper presents the results of the numerical analyses performed and provides information about the implementation of the CBM system on-board the experimental train. (6 pages)
