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.
Action to be funded under this topic should research, develop, and deliver the following capabilities and/or any other relevant capability to achieve the aforementioned expected outcome, on the basis of the public deliveries of FP1-MOTIONAL (GA: 101101973)[2]:
WS1

Developments on all those enablers should also cover important preparatory works with higher TRL for the future set of demonstration foreseen in the Multi- annual Work programme in view of the evolutions of the solutions.
WS2
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
Demonstrate Shared Cybersecurity Services for the Rail System allowing stakeholders in all EU-RAIL Destinations to apply Cybersecurity applications to secure their digital assets, data and communication. 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.
Key Performance Indicators
The action shall actively contribute to measure and monitor the specific quantitative KPIs defined in the Destination description above, including its contribution to the Europe’s Rail Master Plan impacts. Outcomes are to be delivered at a calendar annual basis by each year end.
Collaboration work required with other Destinations
The required collaboration work, including the resources required, with other Destinations included in this call should be foreseen by the action to be funded under Destination 1:
Interaction with the System Pillar
The System Pillar aims to guide, support and secure the work of the Innovation Pillar (i.e. to ensure that research is targeted on commonly agreed and shared customer requirements and operational needs, compatible and aligned to the system architecture), and the Innovation Pillar will impact the scope of the System Pillar where new technologies or processes mean that innovations can drive a change in approach, as well as delivering detailed specifications and requirements. In this respect, the proposal should allocate necessary resources that would be dedicated to areas linked to the System Pillar conceptual and architecture works – particularly addressing specification development and demonstration activities following architectural aspects, stemming from the work of System Pillar:
The EU-RAIL System Pillar is producing specifications and other relevant documents [6]. In general the documents applicable to the Destination 1 should be used. If it is considered documents are not applicable, the proposals shall explain the reason(s) for not using them (to note the application of the documents may still be required by EU-RAIL). During the action to be funded under this Destination, there may be updating of the documents, including based on feedback from application in technical enablers and demonstrators. Relevant feedback should be provided on a regular basis to EU-RAIL and the System Pillar.
In consideration of the timing of the activities, the planning as per the STIP should be taken into account and referred to. The proposal shall foresee feedback to the SP harmonization specification as part of the relevant deliverables, as well as capacity for joint workgroups to justify SP requirements, on the basis of the demonstrations, as mature for harmonization output.
The alignment of the activities will primarily take place during the Grant Preparation Phase and ramp up phase of the awarded proposal, and there will be continued, structured and regular interaction through the life of the project.
The action shall actively contribute to the update of the EU-Rail Standardisation and TSIs input plan (STIP) wherever relevant. Similarly, the action shall contribute to the development and implementation of EU policy and legislation including Technical Specifications for Interoperability and Common Safety Methods, as well as to publications of the System Pillar.
