Metrovagonmash: how to make subway

During its long history Metrovagonmash accumulated rich experience. In 1897, he was based as a car-building plant, then mastered the production of tracked vehicles, later together with AMO "ZIL" produced trucks. Now Mytischinsky Metrovagonmash is the birthplace of almost all Russian subway cars.


At the moment, the main activity of the company is the production of rolling stock subway, rail buses manufacture and repair of cars.

 

The main types of metrovagonov produced nowadays are 81-714.5/717.5, 81-740/741 and 81-760/761.
Last year, the company produced 243 subway car, 32 car rail buses to repair the 113 subway cars. Moreover, car repairs in the plant is preferred for the same cost of repair install new equipment, not refurbished old.
For the current year the Moscow Metro ordered 320 cars. The volume is large and therefore it was decided to order the production of bodies in the Tver plant.

For the construction of the car takes about 70 hours. The car starts with the body, it is made in the welding shop.

The shop reminds clip Rammstein. Under a ceiling of smoke, sparks around, crashing and everything merges and crashes after freezing air factory grounds.

This plant kingdom welding. Here, from the individual pipe, profile and sheet metal blanks skilled hands create the "body" of the car.

Metal is cut, adjusted, fixed stand and welded. separately manufactured frame, roof and sides of the trucks.

Next comes the final assembly body, it is already possible to know the outlines of the car.

In parallel, made carts for cars.

Next body through transborder routes are placed on the pitches.

They are the same body brought from Tver, they are fully packed in a white film.

Next, the body is primed and painted. paint shop is aligned with the department for debugging.

Here in the primed fiberglass body wear a mask. The product, though extensive, but relatively easy.

Next applied color and coloring cars.
Interior so far is not attractive.

Next, painted body is transferred to the assembly plant.
The first workshop, which was to produce cars had number 17 and is now at the memory of it all and the three-digit number of shops and end of the number.

In the workshop room 217 make installation of equipment on the truck.
The entire workshop is filled with cars in varying degrees and for different subways.
For example the right head coach leaves for Kazan.

For easy installation, car body raised on jacks. Below it is possible to walk without fear-it is securely fastened.

The plant was introduced "lean production." All parts are manufactured strictly in the required amount, well thought out storage of parts, their availability and the ability to apply the desired part. Thus minimized downtime workers and equipment.

Located under the car engine control systems, pneumatic systems and battery packs. Batteries required to start the car after disconnecting it from the contact line, for example, during an overnight stay.

In parallel routed wiring and insulation.

In contrast to the "license" in the new cars are much more intelligent electronics. Since asynchronous motors they require AC power, and he is a regular contact network, so you need to install a so-called inverter. It allows not only to drive the motor, but also the energy recovered during braking, returning to 50% of the electricity back to the grid.

Unfortunately, in the Russian cars, more foreign equipment. This quality requirement. The Russian partners can not offer the same fuel-efficient and reliable systems, as European.

Cars Series 740/741 designed for Butovskaya light metro line, so they are oriented to work in the open air, as they are flexible and articulated buses, and modern urban design. However, have shown excellent performance and are operated in tunnels, too.

In the "accordion" hidden cables, and very "accordion" comes packaged in a film.

After the end of the assembly and running car gets finished look and lowered onto the cart. And on its wheels goes to coloring and debugging shop.

In the development shop check the operation of all systems, and finish dopodklyuchayut components applied lettering.

Check the dimensions of the mounting frame of the car.

One of the most important tests are running tests. The plant is a branch of a kilometer long, with the upper contact network. that cars could be powered from its roof mounted pantographs, both on the train and connect the cables and hoses.

The plans to build a separate shop Metrovagonmash acceptance of the finished product, it would not put the cars finished in the assembly shop and in a separate room.

Life begins rail bus elsewhere. These are prepared in a separate building.
The main distinguishing feature of this type of transport is the availability of a diesel engine, which allows you to ride on any railroad line regardless of electrification.
Appointment rail bus is malozagruzhennye branches, where there is no need for large diesel trains, they are often bought as staff cars. Boxer engine does not require a lot of space and is located under the floor leaving maximum space for passengers ..

Beautiful plastic kit, streamlined shape and bright glossy paint makes the RA-2 is very attractive.

In parallel, in the same shop going diesel trains for Serbia. Results will be produced 12 two-car trains. In appearance, they are not similar to a Russian train.

On the site of the bridge crane is perfectly visible orderliness and organization of lean manufacturing. All the details are in place, designing the layout of the floor.

Earlier Metrovagonmash had almost a full cycle of production, but the complexity of products and market conditions have forced transfer some production to specialized factories etopovysit quality and reduce the cost of maintaining and upgrading of equipment in such workshops. Sharply reduced injection and forging production, decreased the amount of work in the thermal plant.

Metrovagonmash this stable growing company, which provides an important mode of transportation with modern quality and comfortable cars in Russia, the CIS countries and in some European countries. Product quality is assessed daily by more than fifteen million passengers.
