Turkish State Railways (TCDD) has awarded a contract to Nokia Siemens Networks (NSN) and Thales Spain to upgrade its global system for mobile communications- railway (GSM-R) infrastructure for the Eskisehir to Ankara high-speed rail line.
The deal will see NSN supply a GSM-R network that includes BS 240 base stations and base station controllers to allow reliable voice communication between staff on trains and the operation centre.
NSN will also deliver synchronous digital hierarchy (SDH) transmission equipment and a transport network management system (TNMS).
Thales Spain’s Turkey branch CEO Ferit Peremeci said: "Nokia Siemens Networks’ GSM-R upgrade will help TCDD ensure greater safety for passengers travelling on the Eskisehir-Ankara route."
Under the deal, Thales will supply its onboard digital radio signalling and diagnosis systems that offer additional operational features, such as the reporting and monitoring of exact train position and travel direction.
The feature is expected to increase the frequency of train services on Turkey’s first high-speed line, designed to travel at speeds of up to 250 km/h.
Thales’ radio network will be built with geo-redundant features to help ensure continuous voice communication and signalling, as well as increase the reliability of the system.
The NSN GSM-R is intended to meet the increased safety, interoperability and quality expectations of railway operators, as well as reducing operational costs.
TCDD completed the TRY1bn ($567.9m) high-speed rail line that links the Turkish capital Ankara to the central Konya province in August 2011.
The first section of Ankara-Eskisehir was inaugurated in 2009 and is part of the 533km Istanbul-Ankara high-speed rail line, with the Eskisehir-Istanbul section under construction.
