With the Stuttgart digital node, Deutsche Bahn is equipping a major railway junction in Germany with digital control-command and signalling system for the first time. In addition, the operational regulations are being further developed. The DKS is thus laying essential foundations and making an important contribution to the digitalisation of the railway in Germany.

For the first time, a major German railway junction is being equipped with digital interlockings, the European Train Control System (ETCS) Level 2 and other digital technologies. As various technologies are being used for the very first time, there are numerous deviations from the rules and regulations that have to be assessed and approved as part of internal company authorisations (UiG). As part of the UiG processes for the area of signalling systems, CERSS Kompetenzzentrum Bahnsicherungstechnik GmbH works with NEXTRAIL, confirms the proof of equal safety or explicit risk assessment and issues an assessment report. This means that the regional railway operations manager can approve the UiG in a timely manner.
