Trackside Assets Specifications

The Europe’s Rail Joint Undertaking (EU-Rail), in close collaboration with EULYNX, has published an update of the EULYNX Baseline Set 4 designated as Release 3. EULYNX Baseline Set 4 documentation aims to standardise interfaces and elements of the rail signalling systems across Europe.

This release is a documentation update within the EULYNX Baseline Set 4, continuing the development based on previous releases. The primary focus was to incorporate remaining feedback from the industry and achieve a stable maturity level, fully integrated into the EU-Rail System Pillar. The release has been prepared under the organisation and authority of EU-Rail System Pillar, bringing a part of the EULYNX development under technical authority of the System Pillar.

All specifications related to trackside assets and transversal functions are applicable for both the current EULYNX architecture and the future rail target architecture, agreed in the framework of the EU-Rail System Pillar, therefore published as a single set of specifications under a common publication by EULYNX and EU-Rail, delivering in total 25 specification documents.

In addition to the common documentation release, EULYNX published also additional specifications and supporting documents for the current EULYNX architecture, which are integrated in the EULYNX part of the Baseline Set 4 Release 3, delivering additional 29 documents.

This publication by EU-Rail System Pillar and EULYNX provides the stable basis for ongoing investments and industry developments related to the EULYNX architecture, ensuring both migration and compliance with the future System Pillar target architecture.

The efficient development process and successful sector-wide approval under the umbrella of the System Pillar demonstrate the role of the System Pillar as the generic system integrator and the architect of the future European Union’s railway system, successfully collaborating with sector initiatives, such as EULYNX, to bring all rail sector representatives under a single coordination body.

This release is an update of the Release 2 of Baseline Set 4, which was released in June 2023.
