An electric train is a public transport. Cognitive information about electric trains
Why is the train called this way? This article presents cognitive information about how a train differs from a train, why it carries people only for a short distance. In addition, below are generalized technical information on this form of transport.
An electric train is an electric train, which is used in a suburban communication. That is, it transports people to short distances (no more than 200-250 kilometers). It is worth talking about it more in depth.
Composition of the train, train and their difference
Surely everyone who at least several times in my lifevisited railway stations and aprons, noticed that the different rolling stock (long-distance trains, freight cars, electric trains, locomotives) standing on the tracks is still different.
The long distance train consists of a hugelocomotive (electric locomotive or diesel locomotive) and wagons attached to it. The latter can not move independently, as they do not have engines on wheel pairs that could move them. Therefore, the locomotive carries out the task of moving cars (both passenger and freight).
It should be noted that there are on the railwayelectrified areas and not electrified. The rolling stock to which the article is devoted can move only where there is electricity and, accordingly, a contact wire. Hence the name of the rolling stock - an electric train, an electric train - arose. On the Moscow railway - a direct current, in other regions almost everywhere - variable.
The electric train consists of two head cars,which are installed strictly at the ends of the train, as well as motor and trailer wagons. Has anyone thought about why such a transport always has two "heads" with control cabins, and for freight and passenger trains - no? The fact is that the train is an independent rolling stock, it is unprofitable for the carrier at the terminal station (at the railway station) to again hook the car with the control cab or the locomotive so that it can go in the opposite direction. Railway transport, unlike others, can not make a turn (exception: the ring railway and the turntable at the plant or depot).
Curious readers may have a question: what about trains? They are drawn by the locomotive to the final destination or station, where they are replaced.
Brief description of the train
The train is such a rolling stock,which is located on the roofs of motor cars current collector (pantograph). It is worth noting that it also has electric locomotives. With the aid of a current collector, the rolling stock receives electricity. Why is it needed? First, all devices and systems start to work on the train; secondly, due to the actions of the machinist, wheel pairs of wagons are driven. But that they began to rotate, you need to power the traction motors, located on wheel pairs of motor cars.
A train (train) can onlyits site with the kind of current that suits it. For example, an electric train ER-2 can work only where there is a direct current, and ER-9 - where there is an alternating current.
Where plying, who uses
Not only the inhabitants of megacities perform dailytrips from the city to the region, but also people living in the suburbs. That is why the officially similar type of railway transport is called a suburban electric train. Such an inscription can be found on the station tablets and signs, in the timetable.
Examples of routes are as follows:
- Moscow - Sergiev Posad;
- St. Petersburg - Siverskaya;
- Voronezh-1 - Liski;
- Smolensk - Yelnya.
Apparently, not only in Moscow and St. Petersburgthere is a suburban communication. Anyone can take a trip, because the journey in commuter trains is cheaper than a long-distance train. Only there are no guarantees that it will be possible to go all the way sitting. The fact is that trains sell tickets with the number of the car and the place. An electric train is a rolling stock, the cabin of which has sessile and standing places. The ticket specifies departure and arrival stations, as well as the date of its receipt.
What are the types of electric trains?
The train is a train that has several categories:
- normal (stops at all or almost all stations);
- Fast (stops only at major stations);
- express (has a maximum of one adjacent stop).
Of course, an ordinary train costs less than the rest.
Express is also an electric train with increased comfort, an individual seat for a passenger and a place for luggage.
In conclusion, it is worth noting that the train has always been the most popular mode of transportation for short distance trips.
