as the production of its own renewable energy, or green hydrogen trains in specific routes. It will also be essential to simplify mainten-ance: “Digital signage, smart infrastructure or the continuity in the race to reduce the carbon footprint continue to be perfected,” Muñoz states. In this sense, the ACCIONA Technological Center participates in the European Shift2Rail initiative to accelerate the integration of new technologies. For example? “The development of a new rail system on modular plate that notably reduces maintenance costs and increases the use-ful life of the infrastructure. Vibration attenuation systems from used tires, turning waste into a productive resource. Or the digitalization of infrastructure through techniques of capturing and processing mass data digitization of infrastructure by means of massive data capture and processing techniques on site using drone and laser-scanner tech-nology for subsequent integration into BIM [Building Information Modeling] models,” notes Ignacio Calvo, Director of Innovation and Laser measurement of a section of excavation in Sabadell (SPAIN).
