History
Kazakhstan Temir Zholy, or KTZ, was founded by the government in 2002 as a joint stock company.
KTZ's main task is to develop, operate, and maintain railway transportation in Kazakhstan.
It is headquartered in Astana, and related stock companies own the rolling stock, hauling equipment, and passenger transport division.
Repair facilities have been privatized, and private companies can own or rent rolling stock that can use the rail system.
KTZ is the largest employer in Kazakhstan, with 119,071 employees as of 2020.
Approximately 1% of the Kazakh population are employed by the railroads and affiliated companies.
The company manages a massive fleet of 46,800 freight wagons, 1,700 locomotives, and 2,300 passenger cars.
KTZ's revenue in 2020 was a staggering 1,173.3 billion Kazakhstani tenge.
The freight industry saw an increase in overall tonnage of 3.5% in 2020 compared to the previous year, while passenger volume decreased by 54.5%.
Infrastructure and Investment
Kazakhstan Temir Joly's infrastructure is a vital part of the country's transportation network, with a long history dating back to the Soviet era.
The company's headquarters is located in Astana, and it operates a vast network of 15,000 km of railway tracks. This is a significant expansion from the 16,400 km of track it controlled in 2005.
KTZ is a vertically integrated group, owning and operating all the state railway network in Kazakhstan. It's also the country's largest owner of rolling stock.
The company has a broad gauge of 1,520 mm, which provides a smooth transit at international borders to countries of the former Soviet Union. However, this means there's a break-of-gauge at Dostyk and at Khorgas/Altynkol, where the railway meets China's standard gauge of 1,435 mm.
KTZ has a significant electrification network, with 4,000 km of track electrified at 25 kV 50 Hz AC. This is an essential part of the company's operations, enabling it to transport freight and passengers efficiently.
Here's a breakdown of the company's key infrastructure statistics:
KTZ is investing heavily in its infrastructure, with a capital expenditure program (CAPEX program) in place to rehabilitate and repair its existing railway tracks network. This will improve the reliability and quality of its railway tracks infrastructure, which has been subject to important physical deterioration.
The company is also upgrading its fleet of electric locomotives and passenger cars to improve freight and passenger transport safety, speed, and capacity.

Some of the notable locomotives used by Kazakhstan Temir Joly include the KZ4A, VL80, TE33A "GE Evolution", and TEM2 "Tamara".
Logistics
In Kazakhstan, the rail network is a vital part of the country's logistics. Kazakhstan Temir Zholy JSC, or KTZ, is the country's largest railway company and a key player in the national and regional transport system.
The company is 100% state-owned and owns and operates all the state railway network, making it one of the 15 largest railway companies in the world in terms of freight turnover. KTZ provides economic connectivity with 17 regions of Kazakhstan and with five neighboring countries.
KTZ is investing in a major railroad project to link China and Southeast Asia to Europe for a length of 3,900 kilometres. The project will start at the eastern border town of Druzhba and go to Aktau on the Caspian Sea.
The project will cost between $5–7 billion and is expected to take four years to complete. A link from Aktau to Iran is also required to complete the project.
KTZ is also working on a CAPEX program to rehabilitate and repair its existing railway tracks network, modernize its fleet of electric locomotives, and upgrade its passenger cars. The program is expected to increase the reliability and quality of its railway tracks infrastructure.
In addition to these projects, KTZ has signed a joint venture agreement with AD Ports Group to improve rail connectivity, maritime shipping services, and digital transformation in Central Asia.

State Loans

KTZ issued bonds three times in 2024: to upgrade the Dostyq–Moiynty line, to build the Darbaza–Maktaaral line, and to refinance old debt.
The bonds issued to upgrade the Dostyq–Moiynty line totaled 163.9 billion tenge, with repayment due by 2044 and a low interest rate of 9.25%.
These bonds were issued in digital tenge, and auditors made a fair value adjustment, recording nearly 49.5 billion tenge as a shareholder contribution.
The bonds issued to build the Darbaza–Maktaaral line were worth 44.2 billion tenge and had an extremely low rate of 1.8%.
Auditors made another fair value adjustment, writing off 33.9 billion tenge to capital, since such a low rate can be interpreted as a form of government support rather than a standard market loan.
The bond issued to refinance old debt was 30 billion tenge, at the National Bank’s base rate +0.75%.
In some cases, KTZ received funding at preferential rates, almost interest-free, which was recorded as an additional shareholder contribution, not as debt.
The difference between the “preferential” and “market” value was recorded by the company as an additional shareholder contribution, reducing reported interest costs and improving the company’s financial appearance.
