Abstract

High-speed railway has become a strategic transport in European and Asian countries and more and more countries are developing infrastructures to enter in the ‘High- Speed club’. However, keeping the current good safety record of this conveyance requires extensive maintenance. This paper studies the performance of a high-speed train before and after a major maintenance operation. A set of accelerometers is installed on the train with the aim of collecting vibration signals without disturbing the normal operation of the train. Measurements are taken in the vertical direction of space and in both directions of the Madrid-Seville High-Speed line: from Madrid to Seville and vice-versa. EGRSC and ECBF techniques are applied to recorded vibration signals and the results are analysed. Hence, several frequency regions with significant spectral power variations that are common to both travel directions are identified. These patterns should be taken as a reference for future maintenance actions. Any unexpected behaviour of these frequency regions would indicate the presence of a fault.
