SBB Infrastructure operates an extensive railway telecommunications system, through which we provide the communications networks needed for today's railway operations. One of the main elements in SBB’s innovation strategy is GSM-R (Global System for Mobile Communications – Railways), the digital communications platform that in future will handle all voice and data transmissions required by railway operators.

We build and run the SBB Infrastructure telecommunications networks and are responsible for their smooth, secure operations. SBB, private railways, third-party customers and operations-related facilities count on our robust, state-of-the-art technology.
