The metro, which is often referred to simply as the “metro”, is an urban network of underground railways along which trains run for intercity transport used to carry passengers.
The subway is mainly an underground mode of transport, which distinguishes it from the ground intracity. It is characterized by regularity of movement and compliance with the schedule of arrival and departure of trains, a fairly high speed (up to 80 km / h), a large passenger flow. The most common option for laying subway lines is an underground tunnel. Sometimes the metro comes to the surface. The depth of the tunnels and stations varies even within the same metro.
How many cars in the subway? Let's try to figure it out.
Spread around the world
The longest are the Shanghai and Beijing subways, and the record holders in terms of passenger transportation are Beijing, Tokyo and Moscow. The most common urban underground transport in Western Europe and East Asia. Virtually undeveloped in Africa and sove is absent in Australia and Antarctica. Metro saves urban space, reduces traffic flow and air pollution. This is very true, including for Moscow.
Metro train structure
Metro trains differ externally, internally, as well as in length and technical characteristics. The metro train is monolithic and consists of only a few wagons. Of these, 2 carriages at the edges are head cars, which include cabs for drivers and an electric motor. Between them are from 1 to 6 intermediate cars used exclusively for the carriage of passengers.
The length of the subway car is usually longer than the tram, but less than the train. For different brands, it can be different. So, for ordinary Soviet and Russian cars it is about 20 meters, and for the Rusich model - 27-28 meters. The answer to the question of how many cars are in the metro largely depends on the length of the car.
The metro trains are powered by a direct current network connected to the third (contact) rail, the voltage of which is 750 - 900 V. The track gauge on the territory of the former USSR is 1,520 mm.
In foreign countries, metro trains can operate in an automated mode, which reduces the number of employees.
Types of stations
Metro stations are used to enter and exit passengers from wagons, as well as to accommodate passengers awaiting the arrival of trains. The designs of the stations are different: they can be single-vault, pylon, column and adjacent type. If the tracks are located on both edges of the station hall, then such stations are called island, and if on the one hand, coastal. In the former socialist countries, stations are often decorated in various architectural styles.
As for tunnels, they can be single-track, double-track, but most often they are single-track. In this case, 2 tunnels are laid underground. By the nature of the section, they can be round or rectangular.
How many cars are in the Moscow metro?
The maximum number of cars in the Moscow metro is 8 units, and the minimum is 3. The limit on the number of cars is determined by the length of the station platform through which this train passes. It also depends on the intensity of passenger traffic. Due to differences in the length of wagons for different trains, their number also depends on the manufacturer. For example, on the Filevskaya line of the Moscow metro, different types of trains are used, where the number of cars ranges from 4 (for Rusich trains) to 6 (“Hedgehog”). The number of wagons in a metro train in the Moscow metro also depends on the line. For comparison, consider the length of trains on some of them:
- Butovskaya - 4 cars;
- Kakhovskaya - 6 cars;
- Sokolnicheskaya, Solntsevskaya - 7 cars;
- "Zamoskvoretskaya", "Tagansko-Krasnngopresnenskaya", "Serpukhov-Timiryazevskaya", "Kaluga-Riga", "Kalininsky", "Lublin" - 8 cars;
- Arbatsko-Poskrovskaya, Koltsevaya - from 5 to 7 cars.
And how many cars are there in the metro? In total, there are 5,314 wagons in the Moscow Metro, and 3,656 wagons run on the lines, a little more during peak hours.
Conclusion
Thus, we tried to answer the question: how many cars are in the Moscow metro and what this quantity depends on. It turns out that on different lines it is not the same. Therefore, the answer to the question of how many cars are in the metro depends on the particular metro line.
