The European Train Control System (ETCS) is a signaling, controlling and train protection system currently used by European railways. Its Level 2 is a digital radio-based system.

GSM-R communications technology was the first choice for ETCS Level 2. However, Due to a lack of spectrum availability and its high cost, finally a TETRA solution was selected as a signaling data bearer by KZT.

Hytera TETRA is quite different from the current technology, GSM-R & ETCS, therefore all modifications need to be tested, tailored and verified to interface with the signaling provider.

Since 2012,Hytera has worked with Kazakhstan's national railways company to continuously deploy KTZ TETRA network to support a rail signaling solution based on ETCS in the following three railway lines:
--Kandyagash – Nikaltau, 150KM
--Кызылорда - Шиели(Kyzylorda-shieli),180KM
--Хромтау – Айтикеби( Khromtau-aiteke),600KM

The Hytera TETRA solution used for voice communications and data applications, including train signaling and telemetry data of trains, increasingly help optimize KTZ's freight and passenger operations.

--Totally 48 Base Stations with a minimum capacity of 2 transceivers were deployed by KTZ. These Base Stations are directly connected over IP backbone and all switching task for voice and data are implemented by centralized architecture at 4 separated regional points. 900+ TETRA terminals make train staff's operation more efficient and safer.

--The Network Management System (NMS) is available with a wide range of software, such as Voice and Data Management and a comprehensive Network Management tool, including subscriber management and network performance statistics.

--Redundancy features ensure continuous radio operation. Redundancy of controller, transceivers and power, with fallback operation of the base stations, assures voice and data communication when the network fails.
