4. Conclusion This approach has been applied by VibraTec on different railway structures like bogies, car bodies, infrastructure components, etc. Railway maintenance, renovation and/or replacement costs are major issues for owners. Indeed, remaining life studies are essential to make the right decisions in terms of sustainable development and long-term investments. Operation and maintenance road maps defined from this analysis serve as guides to reach service life objectives. Structural modifications can also be evaluated to optimize life duration. This analysis provides support for investment teams, helping them optimize their asset management strategy. The method presented in this paper is very efficient but needs to be applied with special care and high mechanical expertise.
