Demikhovo Machinebuilding Plant

Demikhovo Machinebuilding Plant or Demikhovsky Engineering Plant (Демиховский машиностроительный завод, abbreviated DMZ) is a major Russian rail vehicle manufacturerer. It is organised as an open joint-stock company.

History
The site was a silk weaving factory originally owned by the Vetrov family and expropriated by the Soviet government.

Since its inception in May 1935, the profile of Demikhov changed several times. There were activities in chemical engineering and the peat industry. But since 1992, the main products manufactured are electric multiple unit trains on 3000 V DC and 25 kV VAC at 50 Hz. During its life, Demikhov has produced seventeen different types of trains and produced over 3,000 examples, operated in Russia, Ukraine, Belarus and Kazakhstan.

On the occasion of its 50th anniversary in 1985, the factory has been awarded the Order of the Red Banner of Labour.

In 1992, the Russian government decided to expand the production of suburban electric multiple units (EMU) at Demikhovo and substantially expanded the plant. In 1993, the first Russian fully formed EMU saw the light of day.

The company became part of Transmashholding in accordance with the Decree of the Governor of Moscow Region Boris Gromov of 20 July 2001, submitted to the departmental submission to the Committee on Transport, Moscow region.

In 2006 Demikhovsky produced and sold 571 trains of types ED4M, ED9M, and ED4MK). Various spare parts sold for nearly $40 million. In 2006 the company presented its new development, the ED4MKM.

In 2007 Demikhovsky produced and sold 630 electric trains of types ED4M, ED9M, and ED9MK.

In 2008 the electric intermodal passenger transport train ED4MKM-AERO was certified.
