Introduction to EULYNX

Current position: Signalling has traditionally been set at the national level, which is hard to integrate when trains cross borders. It is expensive and harder to make interoperable. 

• EULYNX is the digitalisation of the railway signalling industry.  
• The aim is to create open, standardised interfaces between signalling system components.
• Modular approach to signalling, offering standard interfaces for interaction. 
• Reduces vendor lock-in and allows for modular replacement.
• EULYNX publish documents on the architecture and interface specifications.
• Covers architecture, components and interfaces.

EULYNX specifications cover the following subsystems:

1. Signals & Object Controllers (SCI LS) 
2. Points and point machines (SCI-P), Points and Switches
3. Axle counters and train detection (SCI TDS), train block vacancy
4. Level crossings (SCI LC/LX)
5. IP-based communications (including RaSTA) (SCI IO) Interfaces
6. Cybersecurity and networking interfaces (Core)
7. Maintenance and Data Mgmt (MDM) (Core)
8. Electronic Interlocking (Core)

Adjacent EULYNX systems communicate with:

1. Radio Block Centre (SCI RBC),
2. Traffic Management (SCI CC),
3. Adjacent Interlocking (SCI ILS).

15 key partners are: DB InfraGO (Germany), Network Rail/GBR (UK), SNCF (France), RFI (Rete Ferroviaria Italiana), ÖBB (Austria), ProRail (Netherlands), Infrabel(Belgium), Croatia, Czech Republic, Finland, Luxembourg, Norway, Slovenia, Sweden, and Switzerland.
