The Austrian Federal Railway invites tenders for future installations of railway safety equipments for digital interlockings. The introduction of Digital Interlockings in the Austrian rail network involves consistent implementation of an uniform architecture throughout Europe in accordance with the EULYNX specifications in version (Baseline) 4.1 and existing X25oRaSTA interfaces. The project comprises of the central data center, security services platform, network, power supply, object controllers as well as the external systems. The existing infrastructures of the Operation Control Center, Radio Block Center (RBC) and the Level Crossings are to be connected to the Digital Interlocking. The planned target architecture envisages two to three geo-redundant data centers for the Digital Interlocking. In order to streamline processes and ensure a smooth construction process based on digital tools, Austrian Federal Railways is aiming for an end-to-end digital planning.

Experts from NEXTRAIL support the project during the preparation phase of the tender documents i.e., from project controlling with regards to the creation of specifications and system definitions to progress and consistency monitoring of the individual tasks. The objective of the tender is to ensure swift completion and assignment of an agreement for the development, provision, installation, and maintenance of  the new generation of interlockings with a central control unit and distributed external systems.
