The company will provide the onboard cybersecurity and communications system that will link the trains to the control center through secure connections and continuous monitoring, thus facilitating the line's automatic operation.
The first units of these automatic trains are expected to arrive in the second half of 2026, with service commencement planned for 2027.
Teldat's solution is built around its H5-Rail railway router, designed for critical transport environments. This device combines 5G connectivity with multiple operators and redundant SIM cards, along with Wi‑Fi 7 networks featuring advanced cybersecurity functions.
The system not only maintains communication between the train and the control center but also protects the convoy's essential systems, including doors, public address, and passenger information, against unauthorized access and cyberattacks.
According to the company, this measure enhances the digital security of the trains, which will operate "completely automatically," where constant and secure communication is crucial for ensuring service continuity.
In addition to 5G mobile connectivity, the solution includes automatic Wi-Fi in depots for software updates and data synchronization, as well as a wireless network dedicated to technical and maintenance staff.
The equipment allows integration with the TCMS (Train Control and Management System), enabling Metro de Madrid to monitor operational parameters and send remote instructions to the automatic units in case of incidents.
Teldat states that its equipment complies with major European railway regulations for safety, resistance, and electromagnetic compatibility, suitable for operating under demanding conditions of vibration, temperature, and electrical power.
“"Railway transport is evolving towards increasingly automated, connected, and secure models. In this scenario, onboard cybersecurity and connectivity cease to be separate elements and become a single essential technological layer for operation."
With this contract, Teldat strengthens its position in secure communications for critical infrastructures, an area where the convergence of connectivity and cybersecurity is a "strategic requirement" for transport, energy, and essential service operators.
