Kazakhstan Temir Zholy (KTZ, Kazakhstan Railways) and LocoTech-Signal, part of Transmashholding, are starting to operate modern microprocessor interlocking system CTRL@LOCK 400. The introduction of innovative solution on the Kazakhstan railway network will increase traffic safety and contribute to the development of the transit potential. The grand opening of the first station equipped with new system took place on 12 October 2021 in Kazakhstan.

CTRL@LOCK 400 interlocking system is designed for contactless control of switches, traffic lights and other railway infrastructure facilities with the highest level of functional safety SIL4. It is distinguished by modern technical solutions combined with standard interfaces. 

Focusing on modern standards and innovative technologies in signaling CTRL@LOCK 400 is based on the HMR-9 platform developed by the Italian company ECM S.p.A (part of Progress Rail) and has already been used on the railways of Italy and some African countries. Kazakhstan will become the first country on the CIS “1520 gauge” space where the CTRL@LOCK 400 will be operated. 

“We are confident that CTRL@LOCK 400 interlocking system will show its best side. Now we see interest in the system from other countries in the 1520 space”, commented Andrey Romanchikov, Managing Director of TMH JSC and Head of LocoTech-Signal LLC.

In countries where similar systems are already in use, operators see high efficiency and reliability. Implementation of digital technologies reduces downtime and delays in train movements, as well as increases the throughput capacity on busy stations.

On the resolution of KTZ the Mailytogay station became a place for signaling system trial operation. Mailytogay station is located on the Moscow-Tashkent route. The traffic control system existing there was installed in 1957 and has not changed since then.

Specialists of KTZ performed all construction and installation work at the station.

After the test operation of CTRL@LOCK 400 is completed, KTZ and LocoTech-Signal will consider introduction of this system on other sections of Kazakhstan railways.

KTZ and LocoTech-Signal have been cooperating since 2018. In May this year, companies signed a Memorandum of Cooperation in the field of signaling systems modernization at small, medium and large railway stations in the Republic of Kazakhstan.
