- Contributions for portuguese and european projects to help increasing the railway sectorPublication . Coutinho, João Filipe Matos; Farinha, José Manuel Torres; Raposo, Hugo David NogueiraThe Portuguese railway is fragmented in comparison with the European Union's railways. In recent years, there was no relevant investment in the infrastructure or in the maintenance of the rolling stock; as the time went by, they degraded and ended up staying in the workshops. The company Comboios de Portugal (CP) began to make suppressions for lack of rolling stock and unable to meet the commercial passenger service. Currently, CP is recovering a lot of rolling stock that were stopped and degraded over time to have a replacement fleet in case of breakdown. However, CP has tried aiming to do not suppress of commercial trains. However, the railway has been looking to improve preventive maintenance and thus be able to implement predictive maintenance to reduce locomotive downtime and ensure that operations do not have any problems along the way. With Industry 4.0, the rolling stock is interconnected and then information will be collected and filtered and then shows the status of the equipment/component. With this, the railway increases the reliability, availability and maintenance and safety of its equipment, ensuring better commercial and merchandise service. The main objective of predictive maintenance is to prevent breakdowns. Thus, predictive maintenance must ensure quality maintenance to extend the service life of the infrastructure and locomotives. However, around railways, it is important to ensure the quality and state of conservation of infrastructure and asset management. Thus, predictive maintenance is collecting data from sensors in real time to understand the performance and service life of the component under study. Additionally, there are European operators that are looking for solutions and innovations to integrate them in the railway that may have contributions from the National I&D. In the European Union (UE), the railway has evolved a lot in infrastructure and maintenance, thus facilitating the mobility of rolling stock between countries in the European Union to be more comfortable for passengers and, also in cargo transport. Additionally, with climate change, the railway has been invested in because it is a cleaner means of transportation, thus reducing the use of air and road transportation. However, a European Union body, the Europe's Rail, aims to provide an integrated high-capacity rail network, eliminating interoperability barriers to provide solutions for total integration. With these projects and innovations, it will be possible to exploit digitisation and automation to reduce costs, to increase capacity, and to increase the flexibility and reliability that must be shared by the railway sector. Based on this, it will be possible to make a fast, more attractive, user-friendly, efficient transition, thus integrating into a broader mobility system. Europe's Rail will support the development of the most competitive global railway to contribute to the João Filipe Matos Coutinho iv realisation of the European Space, with standardisation of all infrastructures in the member countries, from gauge, catenary, rolling stock, etc. This project aims to give a strategic contribute to the consortium that involves Instituto Superior de Engenharia de Coimbra and Centro de Competências Ferroviário (CCF) to design Portuguese and European Projects in railway projects with the goal of helping Portugal to reach the highest levels of performance in UE according to the state of art. The focus of these projects is the innovation in the rolling stock fleet, reliability, predictive maintenance, remote maintenance, and interoperability of all information.
