The EULYNX Consortium has published a new documentation release Baseline Set 4 Release 1. The Baseline Set 4 Release 1 is a major documentation release, which delivers 51 updated or new documents.

This release continues the development based on Baseline Set 3, and now integrates additional functional extensions for the generic subsystem requirements and for several specific subsystems. This release also includes new specification documents on IT-security. As continuation of harmonisation efforts, this release provides harmonised specifications for EULYNX field element subsystem and interface specifications.

All deliverables are available in PDF format. In addition to the PDF documents, the following supporting artefacts are delivered:

  • For all deliverables originating from DOORS, the requirements interchange format ReqIF is available.
  • For all model-based deliverables, the underlying models are available as an export from the EULYNX model.
  • For all EULYNX field element subsystem specifications, the simulators developed by EULYNX for verification and validation of requirements are available.

Documents are available for download to the registered users. If your organisation does not have yet registered access please fill out the  folder registration form

We are pleased to announce the first official release of the EULYNX signalling engineering data model!

This model has been designed by the EULYNX Data Preparation cluster to improve the exchange of signalling data between IM’s and signalling industry. Seamless automated exchange of information will accelerate (re-)signalling work as engineering information is no longer sourced from a mosaic of plans and documents but from a structured set of data.

Please refer to the EULYNX DataPrep pages for details, deliverables, and explanations how EULYNX DataPrep will contribute to digital continuity in the railway signalling business.

The EULYNX Data Preparation cluster will continue to enrich and update the model following national and international developments. Furthermore, testing and data conversion are on the agenda. New releases are planned every half-year. We look forward to your feedback and questions under This email address is being protected from spambots. You need JavaScript enabled to view it..

Network Rail organised a follow up webinar on the Target 190plus R&D programme, the objective of which is to reduce the cost of ETCS signalling infrastructure to £190k per signalling equivalent unit. 

The slides from the webinar are available pdf here (5.53 MB)

The webinar recordings are available on following links: Day 1 / Day 2

The EULYNX Annual report 2020 is published, giving an overview and status of the work of the EULYNX Consortium, and providing an insight in the plans and activities of the EULYNX members.
