This paper first focuses on DAS technology insertion into the reality of the legacy of complex railway assets and provides one of TTG’s return on experience on DAS deployment.

In a second stage, we focus on steps for integration of DAS with other railway signalling systems. Integration is inevitable and will add value and capability to the DAS offer. Dynamic optimisation of standalone DAS can deliver energy savings of around 5 to 18% to train operating companies. Integration with traffic management systems (Connected DAS) will allow DAS to dynamically take into account other trains’ trajectory. This will allow to optimise the network capacity.

DAS remains a SIL 0 (SIL 1 in the case of C-DAS) system but can operate with Safety Systems such as ETCS. Integration with ETCS will require ETCS display to be modified so that the DAS graphical interface can be represented on the ETCS screen. This integration to a single visual display will ensure the driver can’t get any conflicting advice between DAS and ETCS. The conflicts will be managed through ETCS accepting or ignoring advice coming from DAS.
Integration has started and will continue so that information can be shared improving situation awareness. The value of the DAS advice will be increased. This integration will be made possible by deployment of traffic management systems, new telecommunications allowing constant and secure information flow, ETCS implementation.
