Teltronic Deploys TETRA, ETCS System for Kazakhstan Rail Operator
Tuesday, September 03, 2019 | Comments

Kazakhstan Temir Zholy (KTZ), the Kazakhstan passenger and freight rail operator company, certified the successful integration of Teltronic’s TETRA solution with the European train control system (ETCS) provided by Bombardier Signaling, responsible for the signaling application for the Zhetygen – Altynkol line.

This achievement is the result of a cooperation between both companies, in which Teltronic and Bombardier engineers carried out a coordinated project. After the successful laboratory integration developed in Gothenburg, the system was deployed on a railway line of 300 kilometers, where different densities of the locomotive traffic on the signaling system was applied.

The tests in the field demonstrated that the complete system solution, integrated by TETRA infrastructure and onboard equipment, works stably on the whole back and forth track, under regular and high load traffic operation of the signaling system, according to the requirements and specifications.

This project means the irrefutable proof of the viability and reliability of an ETCS railway signalling system over TETRA. Teltronic has proven the viability of this technology to offer safe and efficient communications in the railway environment, providing voice, operational data — location, alarm and event management — and ETCS signaling data over a single infrastructure.

“TETRA is spectrally more efficient, has a greater range of functions, and is significantly cheaper than GSM-R; that’s why this technology is breaking through even in European countries, where GSM-R is the commonly deployed technology in signalling systems,” said Felipe Sanjuán, Teltronic’s transport business development director. “In other places of the world, where customers can choose the technology to support ETCS, TETRA becomes a very interesting option, especially in those countries that don’t have allocated spectrum to GSM-R for transport.”

Teltronic also has experience developing a Long Term Evolution (LTE) solution for communications-based train control (CBTC) systems. This experience may be applicable to other transportation environments with signalling systems based on different existing protocols such as ETCS, CBTC or positive train control (PTC). Teltronic, as part of its research and development (R&D) cooperation with the main system integrators and signalling applications providers, also jointly tested the suitability of signalling applications over TETRA in high-speed environments.
