We are happy to announce the first update of RCA. RCA Beta is an update of RCA Alpha taking into account feedback from RCA Alpha (from railways, suppliers, sector organizations). RCA Beta mostly deals with corrections, misunderstandings and frequently asked questions.

RCA Beta is released in the form of an updated set of documents from RCA Alpha and with a few additional “Beta chapters” on topics which had generated a lot of interest. New “Beta chapters” include: Platform Independence, Modular Safety, Capacity Effects, Architectural Approach.

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 pdf white paper (213 KB) 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.

All RCA Beta documents are available for download here.

The EULYNX Consortium has published an updated documentation release Baseline Set 3 Release 3. The release includes updated requirements for the interfaces SCI-LX, SCI-ILS and SCI-RBC. This release also includes the Specification of Point of Service – Signalling, defining the interface to the Subsystem – Communication System. Further consistency updates are included in the reference document list, glossary and domain knowledge.

The next update of Baseline Set 3 is scheduled for December 2019 as Release 4.

The EULYNX Consortium has published an updated documentation release Baseline Set 3 Release 2. The release includes updated SCI-TDS specifications and an update to Domain Knowledge. The EULYNX Consortium has scheduled follow up releases of Baseline Set 3: Release 3 in July 2019 and Release 4 in December 2019.

DB Netz and ProRail: Agreement signed for international knowledge cooperation with universities in the signalling domain

Developments in technology are going faster and faster. We also want to achieve the benefits in the signalling domain. The dilemma is that the development of safe systems must be done carefully, the safety assessment of modern technology is becoming increasingly complex and takes longer. In 2017, an initial study showed that formal mathematical methods can help us to solve this dilemma. The signed contract helps us to reach this goal: in international cooperation and with leading knowledge institutes, we develop methods that can be used to demonstrate the safe functioning of the combination of subsystems.
