History of TVZ

August 25, 1898 in Tver began to work car building plant. Already in 1899, the first 13 covered 9-meter boxcars with a carrying capacity of 12.5 tons were presented to the State Railways Inspectorate.

In August 1915, the Tver Carriage Works passed into the possession of the joint stock company of the Russian-Baltic Carriage Works. About 3,000 unfinished wagons were evacuated to Tver from Riga.

On October 26, 1918, the Tver Russian-Baltic Carriage Works was nationalized.

In 1931, in connection with the renaming of the city of Tver into Kalinin, the plant became the Kalinin Carriage Building Plant (and remained so for 60 years - until Tver returned its historical name in 1991).

Since July 1941, the plant has launched the production of military products: artillery shells, mortars, bombs, ambulances. In parallel with this, there was a dismantling of equipment for car building, preparing it for evacuation to the eastern regions of the country.

During the occupation of the city by the Nazi troops, the plant was badly destroyed, ruins lay on the site of the workshops. But already on January 3, 1942 - two weeks after the liberation of the city of Kalinin from the Nazis - an order was received from the People's Commissariat of Medium Machine Building of the USSR on the speedy resumption of the plant's activities. Restoration work has begun. From October 1943, by decision State Committee The defense plant was included in the number of the most important defense enterprises of the country: the enterprise produced 18 types of front-line products.

In spite of a large number of work related to mastering the production of cars for high-speed traffic, the plant continued to modernize the main model range to meet the ever-increasing demand for mass passenger transportation. In 1981, the plant mastered the production of a serial passenger car open type 61-821, in 1985-1987 produced interregional railcars model 61-837 with seating.

On May 21, 1993, an open joint-stock company "Tver Carriage Works" was formed, to which all the main production assets of the enterprise were transferred. The plant continued to produce various types of passenger cars: compartment and reserved seat, staff and SV, open type and with seating, mail and luggage, freight cars and cars special purpose, as well as bogies for passenger cars and for trailer cars of electric trains, wheel sets with axle boxes for bogies of passenger and freight cars; iron casting.

Since August 2008, mass production of railcars in a new stainless steel body has begun. To go from design development before series production cars of the new model range, a large number of specialists, workers of auxiliary industries, and builders had to work hard. The result of the joint work was a radical technical upgrade of the entire production chain.

Simultaneously with the implementation of measures to launch the production of cars of a new model range, work was carried out to increase the production capacity of the plant. If in 2003 the production capacity of OAO TVZ was 625 carriages, then as a result of the work done, by 2009 it had grown to 1,200 passenger carriages per year. To ensure the growth of the plant's production capacity, an intensive path was chosen - equipping the plant's workshops with high-performance equipment and technologies that allow, without increasing common areas increase production volumes: the growth of production areas for the period from 2003 to 2009 amounted to about 3000 m2 (1.5%), while the production capacity of the plant almost doubled.

TVZ today

Currently, the Tver Carriage Works is the main supplier of locomotive-hauled passenger cars for Russian railways. In the domestic railcar building market, the share of railcars built by OAO TVZ exceeds 90%.

The total area occupied by the enterprise is 93 hectares.

The plant includes 10 workshops of the main and 8 workshops of auxiliary production, as well as 3 subsidiaries (related to the main technological cycle): Forge and Press Production OJSC, Vagonkomplekt CJSC and PTNP LLC.

One of the indisputable advantages that the Tver Carriage Works has received due to the massive modernization carried out since 2003 is the high mobility and flexibility of production. This is confirmed, in particular, by the development and start-up in mass production in 2011 of new special-purpose train escort cars: less than six months passed from receiving the technical assignment to the start of mass production. The high mobility of production is also evidenced by the pace of development by the Tver Carriage Works of a new direction for the enterprise - the creation of metro cars, which is carried out jointly with the Metrovagonmash plant, which, like JSC TVZ, is part of CJSC Transshmashholding.

Tver Carriage Works. Most large enterprise Russia and the CIS for the production of various types of passenger cars and components for them. The main supplier of wagons for Russian Railways (and its subsidiaries - JSC FPC). The enterprise is part of Transmashholding. The existing production facilities and technological capacities allow for the simultaneous production of several models of passenger cars, as well as various types of freight cars and special-purpose cars (they were not allowed to shoot at one workshop, they said that they were assembling something there). then secret).

1. The plant was founded in 1898 by the French-Belgian joint-stock company "Dil and Bakalan" under the name "Verkhnevolzhsky plant of railway materials". In 1915, it was renamed the Tver Russian-Baltic Carriage Works, and after nationalization (in 1918) - the Tver Carriage Works. In the period from 1931 to the 1990s, it was called the Kalinin Carriage Works.
2. From the first years of the 20th century, the era of passenger car building began at the plant. In Tver, four-axle sleeping cars are produced for the joint-stock company " International Society sleeping cars and high-speed European trains”, as well as passenger cars of all four classes, double-deck cars, service cars with saloons and sleeping compartments, passenger cars for countries with a hot climate. Archival photo shows a double-decker car, created at TVZ in 1905
3. The plant has a huge area in Tver, and in fact it is the only large operating enterprise in this city. Buildings can be seen on the site. different eras and types. For example, in the photo you see the oldest building - a wooden blockhouse of the water tower of the local boiler house. It has been standing since the 19th century.
4. But we start our tour with a woodworking shop. Now, in a modern wagon, very little wood is used, and earlier almost the entire wagon was wooden. The wood (or rather, it is a wood board), which is currently being used, is impregnated special formulations from burning and decay. Alas, several large fires did not come to this immediately, and then tests showed that the old cars burned down in just a few minutes. But it was. Now the rules fire safety draconian, and the manufacturer is obliged to follow them. Well, the equipment today is not what it used to be, at least look at this CNC machine. Replaces more than 8 classic woodworking machines. Details of any configuration are processed in a matter of minutes, the accuracy is the highest, which affects, accordingly, the accuracy and speed of assembling finished cars.
5. Now this workshop produces almost all the internal stuffing of the car. As a material, along with plywood board and fire-retardant wood, plastic, aluminum profile and others are used. modern materials. But the name was kept historical.
6. For example, if I'm not mistaken, these are plastic facing inner panels. They will be installed inside the car on the side walls over double-glazed windows.
7. A worker glues rubber seals on compartment doors with superglue. About half past 12 in the morning, and he had already used up so many tubes of glue.
8. The plant has carried out and is carrying out the modernization of the machine park. At the enterprise you can find a huge number of modern CNC machines. And this picture with the remote control immediately reminded me of this.
9. Four metal profiles are sawn simultaneously on the machine, which will later become part of the internal equipment of the car.
10. And now let's go and see how the metal parts of the future car are made. For example, this detail was received on the press. The bending accuracy is clearly controlled by the goniometer.
11. This is a sheet of metal after plasma cutting. There are three such installations at the factory. There are 14 more laser complexes- for cutting sheet metal. In the foreground: the sides of the bogie frames have been cut out here. And then some more little things. The rest of the sheet after cutting will be sent for remelting. And back to work. In general, the plant is very sensitive to metal waste, and everything goes back to work.
12. Stamping machines. Part of the small fittings and parts, when their number is large, is not profitable to do with the help of new technologies (expensive and less productive), therefore, such a machine park is used. And next to it is an old press of very shaggy years. But in perfect working order. It was decided to keep it in production as a functioning monument. Sort of like a "playing coach".
13. Painting of parts is carried out with powder paints on an automatic line, but with mandatory visual control and tinting with manual sprayers of complex surfaces.
14. According to the representative of the plant, even in not the most successful years, great importance was given to labor protection and the tools and materials used in the work. Honestly, it was hard to believe right off the bat, but what I saw in the workshops confirms this.
15. Now it's time to make frames for the undercarriages. First, the prepared sheets of metal are joined in special devices and tacked by welding.
16. Next comes the automatic welding robot. It was with these machines that the global modernization of welding equipment began many years ago. Hard-to-reach places are boiled manually.
17. Almost finished cart frame. Since the quality of the trolley and wheelsets is the safety of passengers, the quality requirements are the highest. Moreover, a personal brand of all those who worked with it is applied to the part. And who checked and controlled. All these data are then stored throughout the operation of the bogie and wheelsets.
18. In the foreground, a stack of bogie frames for the subway car 81-760 / 761 "Oka". TVZ makes them for Metrovagonmash.
19. Very smart machine finishing cart frames. Special sensors check overall dimensions and axles. New coordinates are counted from these axes and holes are drilled, edges are processed. Those. if, for example, the bracket was welded with an offset of a couple of millimeters, the machine will recognize this and the hole in the bracket will be drilled independently in the right place.
20. Now the production of wheelsets. The axle itself is machined on the spot, at the railway wheels that come to TVZ from different plants, including the Vyksa Metallurgical Plant, a landing hole (wheel hub) is bored.
21. Nozzle of a wheel on an axis. There is hot and cold method nozzles. This is where cold is used. The inner diameter of the hole in the wheel is slightly smaller than the outer diameter of the axle. And the wheel is pressed onto the axle with a predetermined force. The process is fixed by a special control device with graphic recording of the pressing diagram.
22. Ready-made wheelsets are sent to the assembly of bogies.
23. Finished bogie of a new passenger car design with disc brakes.
24. And this is an old, familiar trolley design. It is now produced at a neighboring plant in Tver.
25. Press for hot forging. On it, with the help of special stamps, details of complex shape are obtained from blanks that are preheated red-hot in gas furnaces.

26. And now let's go to the foundry. In this nondescript photo you see literally a technical revolution in the foundry business. If you need to cast a simple part without cavities inside, then it's all simple. But what if the part is complex and there are cavities and channels inside? There are two options. In the first case, a wax internal model is placed inside the flask. She attaches internal structure and when the metal is poured, it melts and flows out. But simple things can be done that way. What if it's complicated? Then the internal cavities are formed using sand models. Previously, they were rammed by hand, and one person could do about a dozen a day, since the work is very painstaking, requires high precision and all by hand. Now sand models are made by machine. The result of her work is in the photo. Every minute and a half, two sand models pop up. And then, after the part has solidified, the sand of the model is destroyed on the vibration stand and spills out of the part.

27. Bottom part flasks with installed sand model.
28. Issuance of cast iron.
29. The ladle is rather small, since a certain temperature of the metal is required to ensure the quality of the casting - a large amount of metal cannot be poured into the flasks, the cooling time is limited
30. They manage to fill in several flasks and again go to the issuance of cast iron.
31. Foundry finished parts and surface treatment.
32. Now let's go look at the body assembly. First, the car frame is welded on special stocks. Undercarriage equipment is installed and communications are laid.
33. In parallel with the assembly of body frames, the sidewalls of the wagons are made on a special line. The process of assembly and welding is maximally automated, carried out with minimal human participation.
34. Roof sheathing is first welded in flat view, then turns over and on a special stand it is given a semicircular shape. Arcs are welded and the roof takes shape and rigidity.
35. Finally, all parts of the body (frame, sidewalls, end walls and roof) are connected together into a finished product - the basis of the future car.
36. First comes the tacking of all incoming components and parts.
37. Next, all horizontal external seams are welded automatic settings. But the rest - by hand.
38. That's it, the car is almost ready. At least its frame. As you can see, even a heater (or rather, a boiler) has already been installed here.
39. The car after applying the heat-insulating coating and flooring. .::clickable::.
41. Assembly is carried out at positions - only certain actions. Then the car moves to the next position. They come here already painted.
42. The car after installing almost all internal systems. Now it's time to install partitions and mount what the passenger will see in the end. .::clickable::.

43. The plant is the main supplier of passenger cars for the "daughter" of Russian Railways - the Federal Passenger Company. But the product range of the enterprise is very extensive. .::clickable::.44. New carriages with seats are now included in permanent trains, including branded ones.

45. The full production cycle of a wagon takes about 70 days. For a double-deck car, this figure is about 100 days. This is the period from the manufacture of the first part to the finished car. In the car assembly shop, directly on the assembly of the finished product, on average, the car spends 12 days.
46. ​​The main (left) line is occupied by serial cars for Russian Railways. On the middle this time there were staff and dining cars. BUT right line take on other projects. At the time of shooting, these were sleeping cars for international communications(RIC dimension) - a joint project TVZ and Siemens. .::clickable::.47. And wagons for the railways of Kazakhstan.
48. Since 2008, 2,800 different wagons have been supplied for the needs of Russian Railways. These new wagons are used as a priority for the formation and renewal of branded and fast trains. .::clickable::.49. I won’t show you an ordinary compartment car, and there are already a lot of photos. But the presence of an outlet in the compartment is very pleasing.
50. And this is a staff car lift for the disabled.
51. There is a special compartment and a toilet for them only in such a carriage. See how the aisle has been widened so that the stroller can pass through.
52. Now all the bodies are made of stainless steel. At the exhibition site of the plant, the last serial car made of ordinary carbon steel. Occasionally, at the request of the customer, the plant fulfills orders for wagons using the old technology. But for the customer, this is a double-edged sword. The difference in the price of a wagon with a stainless steel body and a regular one is less than a million rubles. And the service life of a stainless steel car is 40 years against 28. By the way, I learned a secret at the plant that tormented me for a long time. You see the inscription "mileage - 450" on the end of the car. This means that an additional metal layer of increased strength is welded on the surface of the automatic coupler and buffers, which ensures the mileage of cars without replacing these wear parts for at least 450,000 km.
53. Double-decker car developed on the initiative of Russian Railways. So much has already been written about him that I will not dwell on it in detail. In the photo the first prototype, a prototype on which the plant tested and mastered the design and technology of this innovative product. To the honor of the plant, it must be said that this prototype was made in just 8 months from the start of design - from the first line on the drawing. Few competitors, even on world market capable of putting into production a completely new product in such a short time.
54. The first subway car produced at the plant. At first, the Oka was assembled in Mytishchi, then part of the order was given to Tver. It has been fulfilled. Now TVZ makes only frames for metro bogies.
55. Sleeping cars of RIC size for international traffic - a joint project of TVZ and Siemens commissioned by Russian Railways. Pay attention to the wide surfaces of the end harmonicas.
56. Let's dwell on this car in more detail. Coupe - in general, everything is familiar.
57. And this is how the door from the compartment opens. It is surprising that it is mirrored from the inside, but in open form she's blocking the passage. Not very good, in my opinion. constructive solution, although the design was developed by one of the giants of the world car building - Siemens.
58. Each car has a shower.
59. And a washbasin under the table. But there is no opener underneath. :)
60. Panorama of the plant. Motor transport shop and railway threads with finished products. Behind the scenes were paint shops, climatic station for testing, the central factory laboratory and much more. But there are already a lot of photos. And until 2030, Russian Railways will purchase 16.5 thousand cars for 774.5 billion rubles, of which 2 thousand will be in the next three years. .::clickable::.

Many thanks to the press service of the Tver Carriage Works and all its employees for their patience and help in preparing the material!

Russia's largest manufacturer of railcars for long-distance trains will celebrate its 120th anniversary this year. Today, the Tver plant develops and produces more than fifty modifications of rolling stock, including double-deck cars for long-distance trains, subway cars, the Ivolga high-speed urban electric train, as well as modern low-floor and almost silent Vityaz trams. In the anniversary year, the plant plans to produce about one and a half thousand cars and bodies - not only for the domestic market, there are orders from abroad as well.

The Tver plant was founded in 1898. His roots are Franco-Belgian. The enterprise made its debut with the production of freight cars, but since the beginning of the 20th century it has concentrated on rolling stock for passenger transportation. After the revolution, it was nationalized. During the Great Patriotic War, they did not manage to evacuate the plant, it was almost completely destroyed, but the enterprise was quickly restored. In Tver (until 1991 - Kalinin) all the cars for the Soviet railways were produced:
