We are pleased to announce the next update of RCA. RCA Gamma is an update taking into account feedback from railways, suppliers and sector organizations. RCA Gamma provides new topics and reorganizes the existing material to be able to move to model-based specifications.

New topics include: Migration with RCA, Principles of the Safety Logic, Business case of RCA for IMs, LSL (Enhanced L3, Supervision, Localisation) and many others (for more detail, check the Release Notes). The first “development snapshots” of the model-based specifications will be made available starting March 2020.

All RCA documents are available for download here

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.
