CAF Signalling Auriga (Level 1 and Level 2) ERTMS

CAF Signalling has developed new signalling solutions that are now being implemented in railway projects around the world, such as in Brazil, Mexico, Taiwan or Turkey.

 The company has managed during the last years to emerge as one of the world leaders in ERTMS systems, both on track and on-board.

During its few years of existence, CAF Signalling has achieved the completion of several ERTMS projects, as well as the contracting of new ERTMS projects in Turkey (Pamukova-Koseköy), Spain (Vandellós-Tarragona, Monforte del Cid-Murcia and the OARIS on-board equipment) and Mexico (Mexico-Toluca).

In addition, other conventional signalling contracts should be added both in Spain and abroad, among which, the Irún-San Sebastián section, the Casablanca station in Morocco, or light trains of Cuiabá in Brazil and Kaohsiung in Taiwan.

Railway control and signalling technology

The company currently focuses on three advanced product families. With these, it undertakes comprehensive railway signalling projects worldwide for all types of lines: high speed and conventional networks, suburban, freight railways, trams and metro lines.

These families are: QUASAR S4e, for electronic interlocking; AURIGA, for ERTMS solutions; and NAOS, for integrated control centres.

Quasar S4e interlocking

CAF Signalling consists of the Quasar S4e electronic interlocking, self-designed and produced. This solution, complying with CENELEC standards, offers the highest safety integrity level, SIL-4. Quasar S4e also delivers a robust architecture 2 of 3 throughout the control process.

ERTMS AURIGA

Today, the most advanced ATP system is ERTMS (European Rail Traffic Management System), which not only acts as a protection system, but also as complementary means of signalling and control. Moreover, it is the only one offering transnational and technological interoperability (among manufacturers). Therefore, ERTMS has become a “de facto” standard for operators and infrastructure managers worldwide.

Given its great significance, CAF Signalling has opted from the beginning for this technology by developing the AURIGA product range, which offers solutions for Level 1, Level 2 and even combinations of both, on track and on-board.

The AURIGA OBS on-board system consists of one of the most compact EVC (European Vital Computer) equipment on the market, 2 out of 3 architecture and SIL-4 safety integrity level. In turn, the AURIGA RBC (Radio Block Centre) equipment also offers the same levels of safety and robustness to manage the level 2 ERTMS solutions on track. Finally, AURIGA L1EM and AURIGA LEU are the basis of the Level 1 ERTMS solutions offered by the company. All these components have interoperability certificates issued by a Notified Body.

NAOS Control Centres

 The control centres are one of the fastest evolving elements from the technological point of view.

The current market requires a very high level of effective integration, allowing the operator not only to access the various control applications (i.e. Traffic control, power management, access control, CCTV, public address, etc.) from a single checkpoint, but also to be integrated into a single interface, making the monitoring and operation of each system possible from a single platform.

Thus, CAF Signalling has developed the NAOS PCCI Control Centres platform. The NAOS solution also has four self-developed applications: NAOS CTC (Centralized Traffic Control), NAOS ECS (Power Management System), NAOS SAM (Maintenance Aid System) and NAOS SCC (Detector Control).

CAF Signalling has currently two work centres, one in Ordizia, administrative headquarters and where the works related to ERTMS onboard equipment are coordinated, and one in Madrid, the infrastructure solutions’ competence centre. In addition, CAF Signalling has a subsidiary in Turkey, CAFSINYALIZASYION.

For those responsible in CAF Signalling, the rapid growth recorded in railway projects around the world is highly positive. According to the company’s Managing Director “these last years have served to develop and make available on the market a competitive portfolio of services and solutions for railway signalling”. In this sense, it highlights that the progress recorded by the company “is being well acknowledge among clients, as we are providing the latest technology for both lineside and on-board equipment.”
