Hytera Mobilfunk, in cooperation with Sistema, has been awarded a contract to deliver a secure mobile radio network based on TETRA technology to Thales Spain, which is undertaking the engineering for a rail project in Turkey called Project Marmaray.
Project Marmaray is a rail-based transportation project in Istanbul, Turkey. The scheme includes the creation of a rail tunnel under the Bosphorus strait, as well as the renewal of 76km of rail lines along the Sea of Marmara from Halkali in Europe to Gebze on the Asian side. The name Marmaray is a made-up word combining the Sea of Marmara with ray, the Turkish word for rail.
The Marmaray TETRA system includes Hytera Mobilfunk’s TETRA trunked radio infrastructure togetherwith train on-board units, which will be integrated by Sistema in collaboration with Hytera Mobilfunk.
The TETRA infrastructure comprises 14 base stations, two centralized IP Nodes for switching and connection to applications, and a comprehensive Network Management System (NMS).
The contract also includes the delivery of 110 on-board units, 60 PT580H portable TETRA radios, integration services with other railway subsystems, as well as roll-out services.
Project Marmaray’s main structures and systems include: the immersed tube tunnel under the Bosphorus, bored tunnels, cut-and-cover tunnels, at-grade structures, three new underground stations, 37 surface stations (renovation and upgrading), operations control centre, yards, workshops, maintenance facilities, upgrading of existing tracks including a new third track on ground, completely new electrical and mechanical systems and procurement of modern railway vehicles.
