The Prime Minister of Georgia, Giorgi Kvirikashvili, presided last October the opening ceremony of the extension of the Line 2 of the Tbilisi Metro, a great milestone for Siemens Spain as it is the first project of the global Siemens Mobility in Georgia.
The Municipal Development Fund of Georgia awarded the contract for the construction of the new University metro station to the joint venture of two Spanish companies Cobra Instalaciones y Servicios and Assignia Infraestructuras, which trusted Siemens Spain for the supply and installation of the signalling systems.
The core of the new signalling system is the electronic interlocking Westrace Mk II, located at University station to control 2.6 km from Vazha Pshavela station. The project includes the installation of point machines and LED signals and also the interface from the new interlocking with the Control Traffic Center, with the existing relay interlocking at Delisi and with the existing signalling system based in speed codes, very common in the countries of the ex URSS.
The extension of the Line 2 has been a challenging project from the technological point of view as the new interlocking technology had to interface with existing technology in order to guarantee compatibility with the rest of the line, fitted with the technology deployed in the 1960´s in most of the former Soviet Union countries.
