Turkish State Railways Picks Nokia Siemens for GSM-R Infrastructure Upgrade

September 4, 2012 6:51 AM EDT
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.

The company is providing its GSM-R radio network equipment, including BS 240 base stations and base station controllers. In addition, it is also supplying Synchronous Digital Hierarchy (SDH) transmission equipment and Transport Network Management System (TNMS).

The Nokia Siemens Networks GSM-Railway meets the enhanced safety, interoperability and quality expectations of railway operators while reducing operational costs and providing additional differentiation potential in the transportation market.

Nokia Siemens Networks is a joint venture between Nokia Corp. (NYSE: NOK) and Siemens AG (NYSE: SI).
