The tracks are the material geometry of the future, and the Lisbon Metro is at the forefront of this transformation, combining underground infrastructure with cutting-edge innovation. The Lisboa2030 – Technological Infrastructures project, led by ISCTE, positions the Portuguese capital as the world’s largest testing center for optical fiber in an active operational setting. With an investment of 1.4 million euros, including 588,000 euros from the FEDER fund, the project aims to test advanced optical fiber and connectivity solutions, promoting urban innovation and collaboration between academia, the public sector, and the community.

The experimental underground ring installed along the Yellow Line of the Lisbon Metro, including tunnels and stations, is a unique test balloon in the world. The strategic location of ISCTE, physically situated over a metro line, allows for unique performance measurements in a real urban environment. According to the vice-rector of ISCTE, Jorge Rodrigues da Costa, the project tests a new generation of optical fibers capable of multiplying the current data transmission capacity up to seven times, highlighting the urgency to evolve current technology.

The thermal neutrality of the underground network is a crucial factor for the stability and efficiency of the tests. The underground infrastructure offers ideal conditions for experimentation, minimizing environmental variations that can affect the performance of optical fibers. This controlled environment allows researchers to explore spatial mode transmission, an emerging technology that promises to revolutionize data communication.

The initiative is not limited to pure research; it has a direct impact on urban resilience, cybersecurity, and the scalability of 5G/6G networks. The low-latency backhaul infrastructure provided by multi-layer optical fiber is essential for implementing these networks, ensuring fast and reliable connections. Moreover, the living lab allows solutions to be tested and refined in a real environment, accelerating the adoption and implementation of advanced technologies.

The project also has a significant economic impact, attracting talent, companies, and international investments. The rector of ISCTE, Maria de Lurdes Rodrigues, emphasizes that the project creates a unique laboratory, not only in Portugal but also in Europe, generating results with global impact. The initiative strengthens Lisbon’s ability to position itself as a hub of scientific and technological excellence, consolidating it as a global technological reference.

The convergence between underground infrastructure and cutting-edge innovation in the Lisbon Metro demonstrates how tracks can be a platform for the next generation of technologies. The underground innovation ring, spanning the tunnels and stations of the yellow line, positions Lisbon as a geographical and technological reference point. “We are creating a test balloon that can scale enormously, transforming Lisbon into a geographical and technological reference point,” anticipates the vice-rector of ISCTE.

The Lisboa2030 – Technological Infrastructures project is not just a technological advance but also a catalyst for strategic development in the capital region. By uniting academia, the public sector, and industry in a collaborative ecosystem, the project lays the groundwork for a more efficient and resilient urban future, transforming the Portuguese capital into a true model of global innovation and progress. The initiative contributes to a smarter, more sustainable, and interconnected Lisbon, where applied research translates into real benefits for citizens.

The Lisbon experience serves as an inspiring example for other cities seeking to integrate infrastructure and innovation. Although Brazil has not yet adopted these solutions on a large scale, the modernization of the São Paulo Metro, for example, demonstrates a similar commitment to continuous improvement and preparation for the future. The CCOx approach, with its high-definition videowall and intelligent monitoring systems, reflects the same vision of integrating technology and infrastructure to improve security and operational efficiency.

Ultimately, the Lisbon Metro becomes a beacon of innovation, showing how the combination of underground infrastructure and cutting-edge technology can transform cities and improve the lives of citizens. The initiative reinforces the importance of tracks as the material geometry of the future, driving urban development and connectivity in an increasingly interconnected world.
