Figures for revenue, net income, and headcount vary substantially by source and year. Russian-language sources report turnover of approximately 27.8 billion rubles and net profit of about 616 million rubles for 2017, with more than 9,400 employees as of 2020; an English-language source reports approximately 9,978 employees and revenue of about US$245 million for 2015. These figures should be treated as approximate and year-dependent.
History
The plant was established in 1898 by the Franco-Belgian joint-stock company Dyle et Bacalan under the name Upper Volga Railway Materials Plant (Верхневолжский завод железнодорожных материалов). In 1915 it was renamed the Tver Russian-Baltic Carriage Works, and after nationalization in 1918 it became the Tver Carriage Works. From 1931 until the 1990s the enterprise was known as the Kalinin Carriage Works, after the city of Kalinin (the Soviet name for Tver).
Early production included four-axle sleeping coaches for the international sleeping-car company Express, passenger coaches of four classes, business and official cars, freight cars, platforms, refrigerator vans, tank cars, and tram components. From about 1904 the plant built double-decker coaches intended for migrants to the Far East. The plant was severely damaged during the German occupation of the city in 1941 and was subsequently rebuilt; during the Second World War it also produced military items, including artillery shells, mortars, mobile workshops, and medical railway cars.
Since 1951 the enterprise has concentrated primarily on passenger coaches. It became the first enterprise in the country to produce wheelsets with roller-bearing axle equipment (1955, per one account). In the 1960s it began large-scale production of air-conditioned coaches with centralized electric power. Notable products of the Soviet period include express trains such as the Aurora (1965), the SVL-class Russian Troika (1972–1973, rated to 200 km/h), and an experimental jet-powered track-testing car.
In 1993, following the Russian privatization framework, the enterprise was reorganized as an open joint-stock company on the basis of the Kalinin railcar industrial association. It later joined Transmashholding.
Products and activities
The company's core activities are the production and sale of passenger coaches and other rolling stock, components and spare parts, and related maintenance and repair services.
- Locomotive-hauled passenger coaches designed for speeds up to 160 km/h and up to 200 km/h, including sleeping, compartment, open-plan, restaurant, staff, and double-decker models.
- Electric multiple units, notably the EG2Tv / EGE2Tv "Ivolga" family (models 62-4496/4497/4498 and successors), used in urban and suburban services.
- Metro cars, including the 81-760/761 "Oka" type.
- Tram cars, produced in cooperation with the Russian public-transport manufacturer PK Transportnye Sistemy (PK TS), including the 71-911 "City Star" series (from 2015).
- Bogies for passenger coaches (e.g., the 68-406x and 68-409x families) and wheelsets for passenger and freight cars.
- Special-purpose railcars, including containers/transporters for spent nuclear fuel (designated TK-84/1, TK-VG-18-2, TK-13T) developed in cooperation with Uralkhimmash.
At various times the plant also produced freight cars, platforms, dump cars, trolleybuses (the PKTS-6281 "Admiral" prototype), and consumer goods.
Market position and recognition
Russian-language sources state that the plant's share of the Russian passenger-coach market exceeded 80 percent around 2010, and other accounts claim the enterprise has supplied more than 90 percent of the domestic market at various points. The company has also exported coaches internationally, including to Egypt in cooperation with Egyptian National Railways. On 29 April 2022 the enterprise received the Russian state honorary badge "For Success in Labour" (За успехи в труде).
Assessment of source reliability
Tver Carriage Works is a genuine, well-documented industrial enterprise with coverage in Wikipedia (English and Russian), the company's official website (tvz.ru), corporate-parent materials from Transmashholding/RWM Capital, and numerous industry sources. Consequently, the subject does not fall under the "Insufficient Encyclopedic Information" category. However, specific numeric data (founding anniversary details, headcount, revenue, market share, and the exact chronology of renaming) differ between sources, and some statements in the readily accessible encyclopedic articles carry citation-needed or dating caveats. Where sources conflict, the figures above are presented with explicit attribution rather than as settled fact.
