DMZ Expanding Its Overhaul And Repair Capacity

DMZ (Demikhovsky Engineering Plant) has expanded its overhaul capacity to 200 cars per year as part of its repair facility development programme. It will help the works in the future to switch to supplying and servicing trains under life-cycle contracts. 

To improve the quality of repairs and optimize technological processes at DMZ, Transmashholding is actively upgrading its production site. Investments in the implementation of related projects in the period from 2021 to 2022 are estimated at 90 million RUB (around 1.5 million EUR). In 2021, DMZ mastered a new type of activity - the Type TR-3 repairs of Class EP2D 3 kV DC EMUs and of Class EP3D 25 kV 50 Hz EMUs. Since 2018, it has been performing overhauls of the previous types of  stock.

As part of the modernisation programme, additional tracks have been laid in the repair shop, which are used for the through passage of cars, and a technological ditch has been equipped for the dismantling of equipment. The commissioning of the new track has made it possible to reduce the time required to overhaul the cars by 800 man-hours per year. In the wheelset and bogie shop, the motor bogie assembly section was modernised. The new component warehouse has been organised, and the flows of new and repaired components have been separated. 

In 2022 on the renewed areas 55 cars of Class EP2D EMUs and 155 cars of the preceding types will be overhauled. DMZ's capacity to produce new EMUs currently stands at 525 cars annually.
