We are happy to announce that the very first version of RCA (reference CCS architecture) is ready and publicly available for feedback!

Based on the 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.

RCA Alpha is not a specification but describes the RCA concepts to allow further discussion and feedback from railways, suppliers, regulators. Based on the feedback the RCA concepts will be incrementally developed into full specifications.

Feedback will be organized with workshops. If you would like to give feedback or to become involved in the evolution of RCA, please contact us.
