Rostov Plant Starts Repairing Donchak Locomotives
Rostov’s repair plant has launched service for 2ES4K Donchak locomotives, replacing long transfers to Buryatia with a new repair site in European Russia.

Rostov Electric Locomotive Repair Plant (RERZ) has begun servicing the 2ES4K Donchak electric locomotives, becoming the first facility in European Russia to acquire the capability. The move shortens the repair route for locomotives that were previously sent to Buryatia.
The plant has prepared its production base and launched a medium-repair program covering 200 locomotive sections. To support it, RERZ upgraded equipment, built specialized tooling, and trained employees. It also assembled more than 200 sets of technical documentation, including repair and testing procedures for major components.
The work covers much of the Donchak’s core equipment:
- power cabinets;
- inductive shunts;
- asynchronous traction motors;
- electropneumatic contactors.
A new repair site for heavy freight locomotives
The 2ES4K and three-section 3ES4K locomotives are built by the Novocherkassk Electric Locomotive Plant. They operate on demanding freight routes and haul trains weighing more than 6,000 tonnes, creating continuous stress on their traction and power systems.
Medium repair for these machines involves more than replacing individual parts. Technicians must identify vulnerable areas and test the most heavily loaded systems with minimal downtime. RERZ’s documentation, equipment, tooling, and trained staff provide the operational foundation for that work.

Until now, locomotives of this type were repaired by a facility in Buryatia. For machines based in European Russia, that meant longer transfers, higher transportation and routing costs, and additional time out of service. The Rostov site adds another repair point to the network and could help reduce queues for a series with a substantial operating fleet.
A 200-section repair program
RERZ says the program is designed for 200 sections, making this an established workflow rather than a one-off project. The plant has received not only authorization to perform the work but also the complete set of technological cards needed to carry it out.
For a heavy freight locomotive, faster access to medium repair directly affects fleet availability. The new Rostov capability gives operators another way to return Donchak locomotives to service without sending them across the country to Buryatia.
