Reliability and Strength


COSMOS is a Train Control and Monitoring System-TCMS based on the TCN communications standard. It is a robust, modular and flexible system, designed for efficient control of the train and easy integration with other train systems.

COSMOS incorporates a powerful HMI that enables the driver to keep all the train's systems monitored in an ergonomic way. This display also enables the maintainer to retrieve maintenance events from an integrated, user-friendly interface.

CAF Power & Automation distributes COSMOS along the entire length of the train, incorporating equipment and functionalities, thus making them "plug-and-play".

Our control electronics engineering provides:

  • Capture and specification of high-level requirements.
  • Specification and programming of the control and diagnostic SW and of the HMI.
  • Testing of the communication with other systems and validation of the equipment in the factory.

COSMOS's characteristics and benefits

  • Standard, interoperable, TCN-based solution.
  • Solution installed and tested in over 100 projects in service with outstanding field reliability.
  • Easy to start up and provides easy train maintenance.
  • Just as easy to configure, by means of the AUNIA configuration tool.
  • Easy to assemble and less wiring required in the train.
  • Distributed modular system, with distributed secondary bus connections.
