In EULYNX (eulynx.eu) European Infrastructure Managers define an internationally standardised signalling system, focusing on common interfaces. EULYNX uses model-based system engineering (MBSE). Infrastructure managers define the appropriate use case descriptions. Modeling experts convert the Use Cases into various SysML model types. The video explains the methods in which modelling and system engineering expertise is combined with signalling expertise. Furthermore the video shows that the analysis of the formal model can be derived from the SysML model. By using formal methods inframanagers can get the `mathematical confidence’ that the EULYNX standard is fit for purpose with national subsystems.

A subtitled version of the youTube is available HERE (click on the link). This page also contains an explanation on why formal methods are used.

As part of an update of Baseline set 2, published on 07 November 2018, updated version of the following document is available:

Eu.Doc.48  Interface specification SCI-RBC  v2.2 (1.A)
 
The document can be found at the usual location under Published Documents, replacing the superceded documents.

When considering the business challenges facing the railways and recognising the opportunities provided by a collaborative approach to Command and Control Systems (CCS), Infrastructure Managers consider that a joint development of a future 'Reference CCS Architecture' (RCA) will have many benefits. A White Paper has therefore been developed to express the thoughts of the members of the ERTMS Users Group and the EULYNX Consortium.
