European infrastructure managers have to optimize cost, reliability, safety, capacity and fast migration. Assets have to be renewed while new technologies are introduced. Incompatibilities create high cost and investment risks. Inflexible old architectures bind the asset owners to technologies and processes which are not making use of the possibilities of today. Expensive migration challenges hinder the infrastructure managers to change their situation fast.

RCA is introducing a modern architecture for the CCS field based on radio based ERTMS and EULYNX. It creates a flexible and safe investment situation by defining a framework for modular standard products as a set of standard requirements used in CCS procurements. 

The digitization of command, control and signalling will only succeed together with a market, that uses standard architectures.

An introduction to RCA is presented in a short video.

Data preparation is the process of writing down the configuration of a yard to which the computer applies the interlocking logic rules. EULYNX Data Preparation describes all the different ways to configure safe signalling systems. EULYNX Data Preparation standard facilitates the exchange of data between the Infrastructure Manager and the signalling supplier. An introduction video on data prep standardisation is now available.

ProRail presents the Smartest Route video as an illustration how EULYNX can be applied today to facilitate future implementation of ERTMS - faster and more cost effective.

In order to enable future partial replacement of system elements European infrastructure managers feel the need for standardisation of the interfaces between these elements. With the EULYNX approach subsystems can be replaced without the need for a complete renewal of the interlocking.

 

In EULYNX the 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. Here under the subtitled version:

The following video describes the why of using formal methods. In EULYNX European Infrastructure Managers define an internationally standardised signalling system, focusing on common interfaces. EULYNX uses model-based system engineering (MBSE). The video explains the methods in which modelling and system engineering expertise is combined with signalling expertise. By using formal methods inframanagers can get the `mathematical confidence’ that the EULYNX standard is fit for use.
