Railway & Mobility

The railway industry has been undergoing a massive transformation in recent years and has shown a strong resilience during the Covid-19 crisis, demonstrating its significance. As the world continues to move rapidly towards digitization, large-scale mobility solutions are being reinvented to meet the growing demand for efficient, safe, and sustainable transportation. The mobility sector is no exception, and is undergoing a transformation as new technologies, such as autonomous vehicles, are making their way into the market. 

Railway modernisation for a greener future: enhancing capacity and reducing emissions

The rise of digital technology and the emergence of new mobility paradigms are revolutionizing the way people move in the 21st century. This transformation is exemplified by the increased efficiency, interoperability, and regularity of rail networks in developing countries.. Increasing urbanisation, combined with the desire to reduce CO2 emissions, is leading public players and major companies to invest massively in rail transport, focus on renewable energy sources, reduce carbon emissions, and promote eco-friendly practices. As for railway operators, they are making increasing the capacity of existing lines their priority by modernising the signalling systems (CBTC, ERTMS, etc.). At the same time, manufacturers are experimenting with different solutions (batteries, hydrogen and, hybrid material) to replace diesel engines and thus decarbonise non-electrified lines.
