Abstract

Climate change poses a clear threat for all human activities, including transport. Railways play an essential role in the sustainability of the transport sector, and thus their reliability against climatic events must be properly ensured. In this context, the project MINFECLIMA aims to contribute to a better understanding of the relation between the railway infrastructure, its maintenance and a changing climate. The project is developed by AZVI S.A.U. and SIER in collaboration with Universitat Politècnica de València within the framework of an International Cooperation Call funded by CDTI and the Spanish Ministry of Science, Innovation and University. This study presents certain parts of the project MINFECLIMA, namely the monitoring of a critical element of the rail infrastructure i.e. an expansion joint. An ad hoc monitoring equipment has been designed to automatically gather data from the joint and couple it with climatic data to carry out analyses that may help determining its behaviour against climatic events. A first assessment of the data gathered so far shows an expected trend, as there is a clear correlation between rail and average air temperature and the expansion joint behaviour. This proves that the designed system is operating as expected, as the collected data is aligned with previous experience and knowledge regarding the operation of expansion joints. Further analyses will be carried out to gain more insight into the joint behaviour. Moreover, a large dataset is being recorded and stored as part of the ongoing project MINFECLIMA. The preliminary analysis presented here for the expansion joint is but a first step on a wider research task. This will be carried out in later stages of the project to achieve a new understanding of the effects that climate has on the rail infrastructure and, consequently, developing more effective maintenance methodologies.
