Europe’s Rail Joint Undertaking (EU-Rail) aims to deliver, via an integrated system approach, a high-capacity, flexible, multimodal, sustainable, reliable and integrated EU railway network for European passengers and cargo.
EU-Rail aims to deliver a high-capacity integrated European railway network by eliminating barriers to interoperability, providing solutions for full integration (covering traffic management, vehicles, infrastructure and services), and achieving faster uptake and deployment of innovation through funded projects. It promotes digitalisation and automation to reduce costs for the rail industry, increase capacity, and strengthen flexibility and reliability. Its work is based on a functional system architecture shared by the sector, in coordination with the EU Agency for Railways.
The European rail system should also be integrated into the wider transport system. EU-Rail supports the development of a strong and globally competitive rail industry.
EU-Rail’s objectives are set to address EU policy objectives, its vision for the rail industry, and the challenges inherent in transforming the rail system.
The EU-Rail partnership seeks to ensure a fast transition to a European rail system that:

Connectors for Federated Data Spaces, TRL7 by 2028
A need for federated data spaces to make all heterogeneous data available to specialized digital applications in multiple domains while a) allowing incremental extensions and avoiding the rigidity of synchronized and centralized deployment timelines and b) providing data owners with the ability to retain control of their assets.
A federated data space is a distributed secure and reliable data sharing and communication infrastructure enabling data federation, access and processing services through standardized interfaces. Incremental extensions of the federated data space are achieved by new devices and systems using the exposed services to add themselves to the federation as they become available, while data asset protection by their owners is achieved by each participant implementing their own data access policies at the interface between their system and the federated dataspace. Connectors using these interfaces must be developed for existing or legacy/proprietary systems to participate in the federation. The sequence of successive federations must take into account the dependencies identified in Annex B between Destinations.
Common Domain Ontology, building upon S2R works on Conceptual Data Model (CDM) and ERA Ontology, TRL 7 by 2028
For Research & innovation and demonstrations activities (within the action) making use of data models related to the interoperability or safety of the rail system, those data models should be aligned with the ERA Ontology[4]. This ontology defines the conceptual framework and the specific terms and relationships for the interoperability or safety of the rail system in the EU that shall be used or where relevant extended. This includes the reuse of the ERA ontology with its semantic artifacts (shacl rules, skos ..) and in cases where it is not sufficient, extensions should be proposed to maintain semantic consistency and interoperability across systems. Those extensions proposals should cover the processes to validate extension to the ERA Ontology with compliant datasets and related competency questions and linked SPARQL queries based on interoperability testbed validation tools (Interoperability Test Bed Guides — ITB Guides[5]). Corresponding documentation should also include any mappings or transformations considered in the Research & Innovation activities and any assumptions made.
High quality data and its accessibility is key to the success of the next generation of railway application and services. Therefore, data does not only need to be of high semantic quality, but also has to be specified by a standardized high-quality syntax.
Digital Twin support, development and execution environment, TRL6 by 2028
As a virtual representation able to imitate the behaviour of a physical system, a Digital Twin is a software implementation of a structural and behavioural model of the represented system. A development environment for Digital Twins shall be composed of standard modelling tools, editors, compilers and debuggers used by specialists to create self-contained, compiled functional mock-up units (FMUs). Searchable libraries of FMUs are also part of the Digital Twin development environment, used to implement higher level FMUs as compositions of submodels through standardized interfaces.
Compiled FMUs are deployed to an interoperable Digital Twin execution environment in which models are initialized with data obtained from the federated dataspace through the dataspace services, and simulations runs are performed to generate the projected behaviour of the imitated physical system.
Cybersecurity, TRL 6 by 2028

Added to the Digital Assets and Engineering toolbox and shareable as a service in a cloud environment, the Shared Cybersecurity Services will provide state-of-the-art cybersecurity procedures, methods and applications.

This topic seeks to enhance the existing railway system by exploring the integration of maglev-derived technologies into existing railway infrastructures to reinforce railways as the backbone of the trans-European multimodal transport network by increasing its capacity and performances. The technical approach to be developed could support the enrichment of the railway system through the integration of maglev-based solution into the existing infrastructure following a principle of overlapping technological layers. This integration aims to implement technological, functional and performance upgrades to existing lines and to ensure interoperability of vehicles with both the magnetic and traditional infrastructure by preserving the flow of traditional trains on the existing railway corridor.
