NSN Rides GSM-R Rails in Turkey

ANKARA, Turkey -- Turkish State Railways, T.C. Devlet Demiryolları (TCDD), is working with Nokia Siemens Networks and Thales Spain to upgrade its Global System for Mobile Communications– Railway (GSM-R) infrastructure for the rail line between Eskisehir and Ankara. Nokia Siemens Networks will supply a GSM-R network that provides reliable voice communication between staff on the train and the operation center.

On-board digital radio signaling and diagnosis systems from Thales will provide additional advanced operational features such as reporting and monitoring of the exact position and travel direction of trains. This feature is expected to enable an increase in the frequency of train services on Turkey's first high-speed line which was designed for speeds of up to 250 km/h. The radio network will be built with geo-redundant** features to help ensure uninterrupted voice communication and signaling, increasing the reliability of the system.
