Europe's Rail Joint Undertaking (EU-Rail) is a pivotal partnership within the European Union, focused on advancing rail research and innovation under the Horizon Europe programme. As the successor to the Shift2Rail Joint Undertaking, EU-Rail aims to enhance the efficiency, sustainability, and competitiveness of the European railway system. The organization drives groundbreaking projects and initiatives that incorporate innovative technologies and best practices, facilitating collaboration among rail stakeholders.

Key offerings include the Innovation Pillar, which delivers operational solutions for a more demand-led and environmentally friendly rail system, and the System Pillar, which ensures coordinated governance for rail system evolution. EU-Rail regularly announces Calls for Proposals and Tenders to foster contributions from associated members, supporting the creation of cutting-edge rail solutions. Through initiatives like the Digital Automatic Coupler program and the Unlocking Rail Success strategy, EU-Rail seeks to mobilize significant investments to modernize rail infrastructure and promote greener transportation across Europe.
