CFL calls for Thales to deliver new Connected Driver Advisory System (C-DAS)in Luxembourg

Providing a logical extension of the existing Thales traffic management system ARAMIS, and prepares with this first step the path towards Autonomous Train Operations

CFL calls for Thales to deliver new Connected Driver Advisory System (C-DAS)in Luxembourg

The CFL ambition is to deliver asafe innovative, high quality performing railway service to ensure customer satisfaction, as well as delivering economic and ecological benefits to the Grand Duchy and cross border operations.CFL has a history of innovative approaches,Luxembourgbeing the first country to offer free public transport, and now via GreenSpeed*paving the way to ATO operations.

Thales has for many years been providing safe and reliable signalling solutions to CFL, and recently concluded a 5th Framework Contract. Branded as “Digital Transformation” CFLstrives to continuouslyimprove theoperation of its networkby evolvingin close collaboration with industry peers. Subsequently, CFL recently awardedThalesto upgrade the Thales Traffic Management System, ARAMIS, with the Aramis C-DAS module–powered by GreenSpeed

The Thales Driver AdvisorySystem(C-DAS),known as GreenSpeed,is an advanced Driver Advisory System developed according to industry standards such as SFERAto favour interoperability while laying down step stones for Autonomous Train Operations (ATO).

GreenSpeed provides unparalleled operational excellence by closely linking the existing traffic management within ARAMIS to the real time situation of the users of the network.Respecting schedules and timing points the optimal speed profile is presented tothe train drivers as simple to follow advice in an intuitive and customised interface. The algorithm-based driving advice ensures improved punctuality and reducedenergy consumption as well asmaintenance cost.It is important for both passengers and train operators today to save energy and reduce CO2 emission, and ARAMIS C-DAS module is a great way to ensure that those expectations are met.

In addition to delivering driving advice, ARAMIS C-DAS module collects journey datasuch as speed, position and Estimated Time of Arrival. These data are available inOCC and in ARAMIS C-DAS BackOfficetoprovidea framework for streamlining the entire traffic operation by analysing and identifying suboptimal conditions. This leadsto further commercial improvements by optimising timetables, dwell times and timing points on an informed basis and brings valuable understanding ofdriver performance.

“CFL is pleased to be working with Thales as we expect the ARAMISC-DAS module to contribute to our efforts in continuousimprovement and customer satisfaction.With regards to rail operation, the ARAMISC-DAS module represents an additional milestone that will enable us to deepen our efforts in punctuality improvementand energy efficiency.This system may also act as acatalyst in the context of CFL’s ATO implementation.”-Henri Werdel, CFL Director of Infrastructure Management.

The C-DAS works together with ARAMIS to optimise the traffic flow, to provide the ideal speed curve, ensuring strict adherence to the timetable, thereby providing a smooth journey, which is energy efficient, as the C-DAS ensures punctuality with the least amount of traction energy used.

By deploying ARAMIS C-DAS, CFLis acquiring a future proof, standards-basedsystem paving the way to an ATO operation. Furthermore,the deployment of the C-DAS will enable CFL to optimise their current infrastructureusage, providing customer satisfaction via a smooth and punctual service and its stakeholders by delivering energy efficiency and reduced Co2 emission.” -Dr. Yves Joannic, Managing Director of Thales Main Line Signalling.

*GreenSpeed is developed by CUBRIS, a Thales Company based in Denmark
