Railway infrastructure systems Seamless telephony Thanks to the reliable radio and telephone network in the Gotthard and Ceneri base tunnels, passengers can use their mobile phones without difficulty. This network also carries large volumes of data for traffic operations.

Landline-based tunnel control system The landline telecommunications network provides the basis for the control system that remotely controls and monitors all tunnel-specific systems such as ventilation, drainage, doors and lighting. Also linked to the control system are further systems that assist the operating personnel in managing incidents or planning maintenance work. Overall control of these landline-based systems takes place in the Pollegio Control Centre (CEP).
The radio network is available to the following groups: y the train driver, who receives status information which is transmitted into the driver’s cab via a special digital radio system for railways (GSM-R); y intervention services such as police and firefighters, who use their own POLYCOM digital radio system for operations in the tunnels; y train passengers, who use the public GSM-P/UMTS digital radio systems to access the services of the public mobile telephony provider and can telephone from the train.
Landline telephone network The data network also forms the basis for the telephone link between the base tunnels and the surface buildings. For this operational communication, Voice Over IP technology is used. Corresponding telephones are installed in the railway systems buildings, the associated emergency columns in the tunnel portal areas, and in the cross passages. Radio network As well as the landline communication network, a wide-area radio network is also available for mobile communication. This is mainly used for tunnel operations and in case of incidents.
