Products and services

With a clear customer focus we rely on our own proprietary technology and a high degree of qualification in engineering and management of “turnkey” projects in signalling, including testing and commissioning, as well as maintenance of facilities.

Auriga: Level 1 and level 2 ETCS

In order to provide an answer to the European Rail Traffic Management System (ETCS), we at CAF Signalling offer our AURIGA integrated solution.

AURIGA ensures high-performance ETCS solutions both for Level 1 (AURIGA L1) and for Level 2 (AURIGA L2). And also for hybrid systems in which both levels exist simultaneously, thus ensuring interoperability (technical and functional) and providing significant benefits in the area of operation and maintenance.



Our ATO (Automatic Train Operation) solution provides a GoA2 (Grade of Automation) based on ERTMS Technical Specifications for Interoperability.

The system is divided into two parts, the ATO trackside and the ATO on-board.

 Quasar S3E: Electronic interlocking

The Electronic Interlocking QUASAR S3e is the foundation of the company’s signalling solutions. A pioneering device in implementation of the EN-50126 and all other associated standards, the Electronic Interlocking S3e – QUASAR has become widely popular and keeps gaining share in new markets and countries. This product has evolved to support new functionalities such as integration of LEU and compatibility with ETCS systems.

The Interlocking integrates self-diagnosis and fault-detection tools, as well as the Maintenance Assistance System (MAS).
