Kazakhstan: The locomotive was designed for the 1520 mm gauge market by Wabtec. The certificate for its serial production was obtained at the end of 2021, and more than 10 such vehicles have already been produced.

The TEM11A locomotive was developed over several years under a contract signed in 2018 between GE Transportation (acquired by Wabtec in 2019) and the Kazakhstan Temir Zholy (KTZ) national railway company. It included the delivery of 300 such locomotives. In October 2021, Deputy CEO of KTZ-Freight Transportation Kanat Kobesov indicated that the entire specified fleet should be delivered to KTZ by 2030.

At the end of 2020, the first 2 prototypes were manufactured at the LKZ plant of Wabtec in Kazakhstan and sent for trials. In December, the vehicle received a certificate of compliance with the requirements of TR EAEU 001/2011, and the production of 300 such shunters was approved. According to the Railgallery website, more than 10 TEM11A locomotives have already been produced, taking prototypes into account.

The TEM11A diesel locomotive power is declared at the level of 1,100 kW, while the capacity of the diesel generator set can be programmatically increased up to 1,500 kW. A V12 diesel engine and an asynchronous generator are used. The start-up traction force is 367 kN, and in the continuous mode it is 275 kN. The specific fuel consumption is 199 g/kWh, and 6 kg of diesel per hour is consumed at idle speed. The tank allows equipping TEM11A with 6,000 liters of fuel.

In 2020, in the Kazakhstan temirzholshysy newspaper, the head of marketing and sales at LKZ Rauan Donsebaev indicated that “the extended interval between scheduled repairs of the diesel locomotive is 180 days”. The declared service life of TEM11A is 40 years.

According to the technical specifications on the LKZ website, the TEM11A diesel locomotive is capable of passing curves with a minimum radius of 80 m at a speed of 5 km/h. The vehicle is four-axle, but LKZ declares the possibility of its adaptation to six axles.

Also in 2021, Director for Technical Policy at KTZ Talgat Kanatbaev noted that TEM11A, as well as the TE33A and TEP33A mainline diesel locomotives produced by LKZ, includes the BORT locomotive security system developed by the Transtelesoft company. According to him, the system implements the functions of ensuring traffic safety, automatic driving, driver control, video recording and loopless diagnostics. The built-in diagnostics of the automatic locomotive signaling system eliminates the need for a locomotive to enter a fixed loop to check this path, and so the check time is reduced from 40 to 2-3 min while the service interval is increased.

As to the Zeleznicni magazine media, 19 TEM11A diesel locomotives are to be built this year. They can also become the basis for battery modification. Thus, Wabtec and KTZ signed an MOU which, among other things, involves the delivery of 150 battery shunters using FLXdrive technology.

Founded in 2009, LKZ has produced over 400 locomotives to date and employs 700 people, according to Wabtec. However, LKZ itself indicates that the design capacity of its production is 100 diesel locomotives per year, and the number of employees will increase to more than 1,000 people at full load.

In 2021, the Ministry of Industry and Infrastructure Development of Kazakhstan reported that since 2010, more than 11,000 components and parts have been produced locally as part of LKZ orders, which made it possible to reach the share of Kazakhstani components in rolling stock at a level of more than 74%. LKZ held a fair for companies specializing in metal structures manufacturing in May this year. The plant officially noted that due to the increase in the production of diesel locomotives in the next few years, its shareholders and management decided to place orders for large components and parts from third-party companies.
