New Stadler passenger railcars have not yet entered service in Kazakhstan due to concerns regarding their braking system, Talgat Aldybergenov, Chairman of the Management Board of JSC NC Kazakhstan Temir Zholy (KTZ), said at a government briefing.

As the national rail operator, we cannot put railcars into service without ensuring the safety of our passengers and the safe operation of trains on our network. As soon as all of our concerns have been addressed, the railcars will be launched," Aldybergenov said.


KTZ noted that the Stadler passenger railcar project has been under implementation for nearly two years. According to the company, tests conducted in December last year revealed issues with the braking system, which were subsequently confirmed by the manufacturer.

Additional testing of the railcars was carried out between February and May. Test reports covering operations at various speed levels are currently awaiting approval by Stadler.

KTZ stressed that the identified deficiencies were discovered during standard certification and inspection procedures that all new railcars must undergo before entering commercial service.

Stadler has confirmed the existence of these non-compliances. Since February, we have been conducting tests. However, there is a difference in positions. We maintain, and are confident, that the braking systems currently do not comply with regulatory requirements. We insist on this position and have all the supporting evidence, which has also been provided to the manufacturer," KTZ said.


During a government meeting, Prime Minister Olzhas Bektenov said further delays in the introduction of Stadler rolling stock were unacceptable amid continuing passenger complaints about the condition of railway carriages.

Complaints from passengers about the condition of railcars continue to be received. Further delays in the delivery of Stadler railcars are unacceptable," the prime minister said.


Bektenov instructed the Ministry of Industry, together with KTZ and Stadler, to ensure the delivery and commissioning of the passenger railcars as quickly as possible while fully complying with all technical safety requirements.
