Ust-Katav Wagon-Building Plant

The Ust-Katav Wagon-Building Plant, officially the Ust-Katavskiy Carriage Works named after S. M. Kirov (Усть-Катавский вагоностроительный завод имени С. М. Кирова) is a railroad carriage works in Ust-Katav, Chelyabinsk Oblast, Russia.

From 1947 to the end of the 20th century (before the series KTM-8), the factory built trams under the brand name KТМ, which is often used as an informal designation for subsequent models with digital items (e.g. tram 71-619 is also known as KTM-19).

History
The factory was founded in 1758.

The plant built streetcars (trams) from 1901. The first tram was made for Tbilisi. In 1960, a special design bureau for streetcar transport design was established, and about 20 streetcar models were developed. The plant set a world record for the production of one type of vehicle (KTM-5, 14.991 units).

Currently, the plant produces low-floor trams of different variations of models 71-623 and 71-631. In 2006, the plant built its first 71-630 low-floor articulated trams (tested in Moscow). In 2009, UKVZ offered two 71-623 partial low-floor, single-section vehicles for trial operation in Ufa and Nizhny Novgorod. In 2010, additional trams of these models were built for Moscow, Perm, Nizhnekamsk and Krasnodar. The plant also produces trim spare parts and provides tram maintenance services.

In addition to streetcars, the plant produces gas pressure regulators, pipeline valves, pumps and consumer goods.

By Presidential Decree of the Russian Federation number 772 of June 11, 2011 and Federal Decree number 1159-r of July 7, 2011, the Federal State Enterprise Ust-Katavsky Automobile Production Plant Kirov was renamed a branch of the Khrunichev State Research and Production Space Center.
