Joint Final Event - LinX4Rail & LinX4Rail-2

23 May 2023, Paris, UIC HQ

System architecture and Conceptual Data Model for railway, common data dictionary and global system modelling specifications.

Joint Final Event - 23 May 2023 - Face-to-face event only

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 and LinX4Rail-2 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.

Furthermore, the LinX4Rail and LinX4Rail-2 projects, in prototyping the Railway System Architecture paved the way to the System Pillar which was implemented from 2022 to actually develop it and connect it to the EU Rail Innovation programs.
