  • Evolution
    Formal change management has been applied since Release 1.0. This includes the intake and processing of change requests from users. Changes are summarised in the release notes for each new version. A six-monthly release frequency is foreseen.

  • Contributors
    The EULYNX Data Prep model resulted from the joint effort of the infrastructure managers in the EULYNX consortium.

  • Open source developments
    The EULYNX Data Prep inspires external open source developments:
    • A-Plan is a tool which can convert legacy track data and existing CCS infrastructure data of an infrastructure manager into EULYNX XML. The tool is an open source  software that is continuously developing to fulfill the geodata requirements of participating infrastructure managers. It currently supports French and German data and enables the visualization of EULYNX XML.

Data preparation today

Every Infrastructure Manager has a long tradition of presenting signalling information in given shapes and formats, inherited from the days of paper and steam.



United Kingdom:



The signalling supply industry ingests and interprets this information, and processes it. Ingestion and interpretation of data are the weak links in the chain.

IT for signalling is a niche industry because it is closely tied to national markets.  

Customising software is expensive when each IM has his own model, e.g. PlanPro, IMSpoor, SDEF, Gaia. Software developers rarely have both rail and IT know-how so the language, jargon and culture remain barriers to developing pan-European software packages.

EULYNX DP is designed to help data break out of the national silo.
