The company Sistemas y Montajes Industriales SA (SISTEM), part of the CPS Group, has been awarded the first official tender in Spain for the preparation of the infrastructure necessary for the implementation of the FRMCS (Future Railway Mobile Communication System), the new European standard for mobile railway communications.

This contract marks a milestone for the national railway sector, as it represents the first concrete step toward the transition from the current GSM-R system to a communications network based on 5G technology, which is more secure, efficient, and prepared for the challenges of the future.

The project, which will be developed in the test section León–Matallana, is part of the international program ERJU (Europe's Rail Joint Undertaking), a European initiative for the development of a more digitalized, competitive, and sustainable railway system. In this context, Adif is leading the FRMCS implementation trials in Spain, with the goal of beginning technical trials in 2026.

Profound transformation of the sector

The FRMCS, developed by the International Union of Railways (UIC) in collaboration with European industry, is based on 5G standards and will enable more efficient integration of control, signaling, video surveillance, emergency communications, and operational services systems. It will also facilitate the progressive automation of railway operations, improving safety and reducing operating costs.

In the words of management: "The transition to FRMCS not only involves a technological change, but also a profound transformation in the way rail transport is communicated and managed. It's a qualitative leap toward a smarter, more interoperable, and safer network."

With a solid track record in the deployment of telecommunications networks, including its participation in 5G projects for critical infrastructure, SISTEM thus consolidates its leadership as a technological integrator in the railway sector. This award reinforces its strategic role in the evolution of rail transport toward more connected, automated, and sustainable models.
