We are pleased to announce the next update of RCA. RCA Baseline set 0 Release 1 is the fourth public release (after Alpha, Beta and Gamma) of the documents prepared by the RCA initiative.

This release includes several new architecture documents. Content which belongs to the specification in strict sense is being prepared in a MBSE (model-based systems engineering) approach. Detailed information about this release is available in the release notes. 

All RCA documents are available for download here. 

If you would like to give feedback or to become involved in the evolution of RCA, please contact us.

RCA in a nutshell: Based on the RCA White Paper published in summer 2018, the RCA initiative is driven by several railways organized in EUG and EULYNX. The RCA initiative strives for a substantial improvement in cost, capacity, safety, reliability of the CCS (command, control, signalling) system. RCA starts with radio-based ETCS cab-signalling and EULYNX interfaces and adds a harmonized architecture with clearly defined interfaces leading to an upgradable system with interchangeable components. RCA includes the game-changers such as ATO, moving block, train-borne localization, FRMCS. An introduction to RCA is presented in a short video.

EULYNX consortium informs on the The Digital Rail Summer School, that will take place 21-25 September 2020 near the new ''Digital Test Field” at Annaberg-Buchholz. The event is aimed at students who are interested in technical systems at Deutsche Bahn.

The participants of the Digital Rail Summer School 2020 will be able to gain experience in the practical implementation of software projects for rail operations. EULYNX, also presented at the event, will demonstrate co-simulation with hardware-in-the-loop as well as control of a switch motor from the simulation model.

The EULYNX Consortium has published an updated documentation release Baseline Set 3 Release 5. The EULYNX Baseline Set 3 Release 5 is an update within Baseline Set 3 after the earlier Releases 1-4. It delivers 42 updated or new documents.

This marks the completion of Baseline set 3, making this release a stable and comprehensive set of specifications, serving as basis for industry developments and infrastructure manager deployments. With Release 5 the current baseline set will be closed for changes in functionality or new functions. Please note that a minor update is planned in form of Release 6 (Sept 2020), limited only to SCI-RBC in order to integrate the functionality of ETCS L1 (SCI-CEC) into SCI-RBC.

Future developments in EULYNX will be introduced as part of Baseline set 4 (planned from December 2021 onward).

All deliverables are in PDF format, deliverables originating from DOORS are also available in requirements interchange format ReqIF.

Documents are available for download to the registered users. If your organisation does not have yet registered access please fill out the  folder registration form . 

The EULYNX Annual report 2019 is published, giving an overview and status of the work of the EULYNX Consortium, and providing an insight in the plans and activities of the EULYNX members.
