    The EULYNX Data Preparation model is created from joint effort of infrastructure managers of the EULYNX Consortium. 

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.  

Data preparation tomorrow

Seamless machine-to-machine flow of information between IM and signalling suppliers.

This is the key EULYNX DP use case – but it can do a lot more.

Example of a typical EULYNX DP diagram

The diagrams are designed for

  • Accessibility and focus
    • Presentation in HTML format
    • Subject-matter diagrams collect all information
    • Users browse for information at their ease
  • UML classification and relations
    • Semantics: what does it mean
    • Associated attributes
    • Generalisation – Specialisation: helps keeping it as simple as possible but not any simpler
    • Relations: Class A needs/owns/knows class B, e.g. How does a signal relate to a route
  •  Examples
    • The semantics are supported by graphc examples
    • Examples support the communication between signalling and IT experts.

EULYNX DP versus conventional information models

The EULYNX DP model represents signalling know-how. The graphics support understanding that is accessible to both IT- and signalling professionals.

A conventional XSD model is tied to XML, has little to no visual support. XSD’s are familiar to IT professionals but difficult to grasp for signalling professionals
