Transformations in the country in 1985-1990 had an impact on the fate of the Mytishchi plant: by decision of the Council of Ministers of the USSR in 1987, the plant passed under the control of the Ministry of Heavy Machine Building of the USSR from the Ministry of Automotive Industry of the USSR. At the same time, the plant built a new car-assembly building with an area of 17 thousand square meters.

The plant switched to the production of modernized metro cars models 81-717.5 (head car) and 81-714.5 (intermediate car). Modernization consisted in increasing the reliability and fire safety of its units and systems. In the early 90's, the production of new generation cars was mastered - models 81-718 and 81-719 with traction thyristor-impulse electric drive of direct current.

In 1986, the production of a new model of the ZIL-MMZ-45054 truck began. It was the original development of OGK, the engine of the car uses natural gas.

In March 1987, representatives of labor collectives gathered in the Cultural center of MMZ for the election of the new general director of the association. The place of the former head V.N. Donskov, who with honor has left on the deserved rest, the young and vigorous director of the Neftekamsk plant of autotrucks Yu. A. Gulko has taken.

The new director started a lot of work to create new generation metro cars, organized the construction of production buildings for new cars. In addition, Yu. A. Gulko engaged in active housing construction for workers, as housing shortage was one of the reasons for staff turnover.

Since the late 80's, the geography of foreign economic relations of the plant has gradually expanded. The structural reorganization of the enterprise has begun: the council of labor collective (STK) which has subsequently approved the new structure of MMZ management.

It provided for the establishment of three production facilities at the enterprise: cars, dump truck and serial production. In the late 1980s, cooperatives began to emerge at the plant.

In the beginning of 1990, the association began to transfer to new methods of management, as a result of which it was decided to take the plant for lease with the subsequent right to purchase it from the state.

April 20, 1992 at the founding conference of the labor collective of the association it was decided to transform the plant into a joint-stock company Metrowagonmash, whose chairman was Yu. A. Gulko.

In 1993, the plant demonstrated a new model of the Yauza metro car, which represents a new milestone in the history of metro construction. It uses many of the latest technological advances.

The plant met its 100th anniversary with dignity: the joint-stock company managed to preserve and multiply the production potential, provide the main and auxiliary shops with work, attract more consumers both on the domestic and foreign markets. Products with the Metrowagonmash logo are exported to Germany, Iran, Egypt, India, Saudi Arabia, Mongolia, China.

In 2001, Metrowagonmash produced production that produces metro cars of new modifications and rail buses. The design of the rail bus differs from its novelty from all the earlier known in the railway transport. The rail bus is designed to transport passengers on non-electrified sections of suburban and inter-regional railways.

In 2005, CJSC Metrowagonmash became a part of CJSC Transmashholding, the largest association of transport engineering companies in Russia, producing mainline electric locomotives, diesel power units, industrial electric locomotives and shunting locomotives, freight and passenger cars, ship and diesel locomotives, car casting, electric train cars. Such partnership guarantees the increase of the financial stability of the enterprise, the receipt of additional orders, access to the international arena, access to advanced technologies, the creation of equal conditions in the market activity.

In 2010, an important event took place in the market of transport engineering in Russia: the French company Alstom Transport and CJSC Transmashholding signed an agreement on strategic cooperation in the field of technology, production and finance on March 31. In accordance with the agreement, Alstom will support the modernization of Transmashholding's plants and the development of a new generation of railway equipment for the Russian market. For OJSC METROWAGONMASH a new stage of renovation has begun, in order to improve the organization of production and labor, a number of new standards and regulations.

Today Mytishchi Machine Building Plant  is not only a production, machinery, transport, and auxiliary services, it is also a widely ramified network of social infrastructure institutions: kindergartens, health camps, medical station, shops, canteens, libraries, etc.

OJSC METROWAGONMASH is a powerful enterprise providing uninterrupted operation of transport systems in Russia and many countries. The enterprise's activity, its bright history and convincing presence in the market of transport engineering give an opportunity for pride not only to its employees and partners, but also to all passengers of subways and railways- to all the inhabitants of our country.
