The railway sector is currently acting in a fragmented way and in silos corresponding most often to physical or functional subsystems or use cases, and the different owners/managers of the overall infrastructure at regional/national level, without global extensive view or full control of the global system involved by rail operations.
With the progress of digitization, analogue devices based on relays were progressively substituted by digital ones, and it is more and more evident that enabling the communication between already existing digital tools for various subsystems can be beneficial. What is missing is an efficient, automated and standardized way for these integrated and interplaying systems to act as one ecosystem: sharing, integrating, identifying, correlating and exploiting the right data at the right time.
In order to meet these challenges, the objective of LinX4Rail is to develop and promote a common Functional Rail System Architecture for the Rail sector, as requested by EC. It will be supported by a widely adopted Shift2Rail Conceptual Data Model (CDM) that will, with the commitment of the Shift2Rail members, establish the standard for interactions between legacy and new systems, thus ensuring sustainable interoperability between systems.
The ambition of LinX4Rail is to achieve a comprehensive approach for the CDM, as a models’ federation, global system modelling specification and the strategy for implementation of technological breakthroughs.
Expected main OUTPUTs
The technical work is structured around 5 work packages, aiming at:
WP01 - Management of project, coordination with other projects and IPsWP02 - Definition of common data dictionary (Semantics, Ontologies)The objectives of the work package are:
Development of the definition of concepts and their semantic, that can be used by other dictionaries, ontologies, data repositories, applications;
Integration of output coming from previous works or similar projects to update the dictionary.WP03 - CDM/ global system modeling specification & development
Creation of S2R-CDM (Conceptual Data Model) as a consistent federation of data railway system models, based on existing ones coming from RTM, EULYNX, railML and IFC.Rail and not only railway related ones, such as the ones from the OGC Sensor Web Enablement suite for the diagnostic data and processes and so on.
Evolution and enrichment of CDM according to other S2R project requirements.WP04 - CDM Demonstration
Development of three demonstrators in order to test and refine the proposed CDM solution, and to prove the applicability to other S2R projects on which the WP3 work has been based.
Definition of the quality indicators and consequent evaluation of the performances of concepts proposed with respect to the developed use cases.WP05 - Strategy for implementation of technological breakthroughs (including RCA)This WP will work on a first comprehensive architecture, mapping the technologies for the implementation of a new integrated railway system approach.
In order to do so, we will develop a vision and concepts for a Functional Railway System Architecture
from ongoing initiatives inside Shift2Rail
from RCA, OCORA and other rail initiatives (e.g. IFC, RTM, …)
from benchmark from other sectors
This WP will produce successive releases of the common Functional Railway System Architecture and will integrate it into Shift2Rail carrying out the change management process.
This structure aims at streamlining the inputs (“subjects”) from running projects and other initiatives outside Shift2Rail and analysing them. The Programme Board will approve or not the proposed subjects. LinX4Rail will provide specification requests, the projects will execute the technical impact assessment. LinX4Rail will present the technical impact assessment to the Programme Board. Based on the recommendations, the decision of an integration into the project is taken at the Programme Board level.
Presentation document of the LINX4RAIL 3rd WP2 Worshop explaining the progresses regarding development of the ontology dictionary.
The document describe the adjustments made regarding the original communication and dissemination plan for the Shift2Rail funded project LinX4Rail. It will describe the tools that will be used to facilitate the wide-spread of information and knowledge from the results created by the project, among and beyond the members of the consortium (and beyond the life of the project).
The LINX4RAIL project aims amongst others at proposing a first railway system architecture, integrating the innovation coming from Shift2Rail (S2R) Research and Innovation activities. Managing this alignment should be performed not only according to technical aspects, but also according to business objectives.
The purpose of this document is to propose a first release of the European Railway Architecture.
The LinX4Rail project ambition, following the co-existence of a number of architecture’s works within Shift2Rail and outside (OCORA, RCA-EULYNX, FRMCS), is to set-up a collaborative platform where all the initiatives would converge in building, in a cooperative way, an Architecture for the European Railway system.
* Please note that this deliverable is undergoing S2R JU review and acceptance processes.
The general purpose of this document is to define governance principles for the Railway System Architecture and the Common Data Model (CDM) which are defined in a first step by the LinX4Rail project, and which will be an important source for the System Pillar within the new Europe’s Rail Joint Undertaking.
Report containing the very first modelling framework to be used and the very first model structure including information layers available for Conceptual Data Model demonstration.

The 24th of June 2021, this Workshop gathered 15 participants who had the occasion to get informed about the progresses regarding the development of a common data dictionary for the railway sector. Precisions were given on:
- the status of the development of the OntoRail tool, with its latest updates concerning the integration of models coming from EULYNX and TRANSMODEL,
This LinX4Rail deliverable aims to define the functional specification for the railway sector ontology with the intended user stories that can be grouped in two macro-categories: browsing of extracted source ontologies (single source or multiple sources) and exploring the establishment of qualified links between concepts of two or more extracted ontologies. The resulting network of ontologies would then qualify as a“dictionary”, the semantic and technical principles. This dictionary is called the "OntoRail" tool.
A particular attention was given in the import process to support the existence, in the ontology repository, of multiple versions of an extracted source ontology to enable in future iterations of OntoRail the consideration of those versions, for browsing purposes (including comparing two versions of the same extracted source ontology) as well as for the purpose of linking ontologies: it is understood that most source models will be subject to future evolutions.
Since the deliverable D2.2 is confidential, only this related News is available on the Shift2Rail website.
With the support of the Shift2Rail Joint Undertaking, the 15th April of June 2021was organised the very first LINX4RAIL Webinar. About 60 participants were gathered on this occasion to be informed on the progress of the project regarding the development of a common Functional Rail System Architecture for the Rail sector.

This webinar was a first of a series where information on the ongoing development of the Rail System Architecture as well as the Conceptual Data Model for interoperability of data exchanges will be presented.
