In South Korea, a vacuum train almost reaches the speed of sound

The vacuum train tests, which have continued in South Korea since 2017, have reached a record speed. It was more than 1000 kilometers per hour.

This is reported by Business Korea.

The principle of such a vehicle, called Hyperloop, was developed in 2012 by Elon Musk. It is based on the movement of capsules through tunnels through an airless environment using magnetic levitation. This allows you to reach significant speeds, and the vehicle moves silently.

At the moment, no company in the world has started the practical use of this transport, which so far exists only in the form of prototypes. One of them is being tested by Korail (Korea Railway Research Institute).

During tests, a smaller version of the capsule accelerated to 1019 km / h. Thus, in South Korea, the vacuum train has almost reached the speed of sound, which is 1193 km / h. It turns out that the South Korean developers managed to break their own record for the Hyperloop when the capsule was accelerated to 714 km / h.

According to Dirk Ahlborn, CEO of US rival Hyperloop TT, South Korea could become the first country in the world to launch a vacuum train transport network. They plan to do this by 2024.

The principle of such a vehicle, called Hyperloop, was developed in 2012 by Elon Musk. It is based on the movement of capsules through tunnels through an airless environment using magnetic levitation.

This is incorrect information. His idea is to form a vacuum hover train.

However, the entrepreneur improved the idea: in his opinion, there is no point in striving to achieve a complete vacuum in the pipe. It is enough to maintain a forevacuum, namely, a pressure of 100 Pa (this is 1/1000 of atmospheric pressure) - further pressure reduction is unprofitable, because it leads to an exponential increase in costs. At the same time, the forevacuum can be maintained using pumps of moderate power and pipe walls made of ordinary steel 20–25 mm thick [8].

However, at the speed envisaged by the project, the vehicle still collides with the oncoming air masses. Musk decided to use them to create an air cushion: special guides and a fan located in the nose of the transport capsule should redirect the oncoming air flow under the bottom. Under conditions of forevacuum, to create an air cushion, it will be enough to provide a pressure of 9,4 kPa, which requires only 200 g of air per second. Thus, Musk abandons the idea of ​​a magnetic cushion, which is much more expensive to implement [8].

But the companies that make hyperloop decided to eat the monster in parts and first master the molovakkum, and only then the air cushion

It will be cheaper to build and launch a supersonic passenger airliner than to build such a tunnel.

I agree. Moreover, there is experience in this area.

[Alexander Vorontsov]

How to say. I think that everyone who stood in Moscow traffic jams for at least a week or tried to park, had the thought that "something needs to be done about this."

Too many people go from the Moscow region to Moscow to work.
There are electric trains, and they are excellent. A swallow, for example, reaches the center of Moscow from Zelenograd in 30 minutes.
It is generally unrealistic to leave Balashikha - the whole expensive is one continuous traffic jam.
Expanding expensive ones is ineffective and in most cases it is simply impossible due to the fact that you will have to demolish everything that is built nearby.

At the same time, now the difference between travel by train and a car can be 1 hour, but this is not enough to outweigh the advantages of "personal space".
But if the time is not 30 minutes, but 10 or 6 minutes, the situation can change radically.

[zwlad]

Maybe just increase the length and number of metro stations by 1,5-2 times?
Make normal transport hubs and increase the number of parking lots near them.
And on good terms, it is necessary to drive all business from Moscow to the regions. Then the regions will begin to develop and traffic jams in Moscow will decrease.

[Alexander Vorontsov]

When I was little, the trains that came to Yuzhnaya were empty, because after that there was only Prague. And from Butovo, which had not yet been so built up, there were buses.

Now at rush hour, trains come FULL. Those. every 2 trains, from the siding between the South and Prague ones, an EMPTY train is served to the South one. Because the crowd gathers and there is no room on the arriving trains.

And as if the question - what to do at the crossings in the center? Where are all these people going.
It is not possible to increase the number of escalators.

For example, from 5 to 8 on the Komsomolskaya ring road, all escalators work only uphill.
To get to it, you need to go through the radial.

So, yes, you rightly need to be comprehensively addressed. Due to one thing - symptomatically, locally, it will be possible to do something but systemically ... only a complex approach.

The Moscow issue can be solved by moving the capital, for example, to Siberia. I took the state. position - go to Siberia, office housing, public transport for everyone, canteens, etc. Build a village in the suburbs for guards, maids, drivers, cooks, guests, etc.
Everyone in sight, brought a suitcase of money who signed up for an appointment with the official, questions will arise immediately at the airport.
They fired the official, rented out the apartment and went to the people.
And so it's all the same that they live in a closed city that is open.

Submarines were not invented by science fiction writer Jules.
Verne followed the engineering findings and sent his hero to sail the seas on a submarine, which was in full swing developed by engineers from different countries at that time.

Like all other science fiction writers, Judge Verne did not invent anything new for the engineers of his time.

All flights to the moon and under water were first described in their works by scientists engineers, and then science fiction writers used these works in their books.
Of course, science fiction ships became large, with toilets, cabins, crew quarters, and other household furnishings.
In fact, only the existence of everyday life was fiction.

Reducing resistance to zero during cargo delivery is neither fantastic nor news.

The news will be the actually built object.

I read your dispute, let me insert my 5 kopecks))
The situation with Soviet science fiction is not new. Moreover, many Soviet inventions suffered the same fate.

I couldn't find it, but somewhere there was a video of how one person spoke very well at the summit, and not Russian, but someone from the West. The bottom line is that he listed many inventions (not a concept but prototypes) that were created in the USSR and Russia. But they did not get success in implementation. Like - the first flew into space, but what market share do Russian telecommunications companies have (satellite broadcasting, etc.)? There have been tremendous advances in computing systems - what market share do Russian companies have, etc.
And indeed it is. Moreover, I graduated from the Lyceum at MEPhI but went into economics and finance. planning. Many of my classmates in the lyceum, looked at it as not degradation, they say, where is the ENGINEER-PHYSICIST and where is the MANAGER? Well, it turned out that there are many inventions, but there was no one to bring all these inventions to mind and make them commercially successful.
And this is very annoying ...

[marchcat]

Well, this does not threaten us, because the ticket price (for sure) will be more expensive than a flight on a rocket.

[Horon]

The cost of building, maintaining and repairing such highways will be sky-high, especially at Russian distances. Plus, there will be high requirements not only for the tightness of such a line, but also for the rolling stock. The slightest violation of the tightness and the dead will arrive before the final. So the price will be great everywhere. Scientists wrote about such vehicles even when Elon Musk was himself at the manufacturing stage, so this is not his idea, he just decided to repeat it.

The use of such transport for passenger transportation is doubtful. Acceleration and overload. But for the transportation of goods is quite suitable.

The state corporation Roskosmos plans to rename the state trading corporation Roscosmos from 2021 - this decision was made due to the fact that revenues from space exploration are seriously falling.

The head of the company, Dmitry Rogozin, explained that the company can earn more from trading than from space launches. Russia, he believes, has a "unique space brand that can bring in millions."

“On the example of mugs. Who will buy a mug with Elon Musk? None. This is not a brand, it is not interesting to anyone. And everyone will buy a mug with Gagarin, ”he said.

At the same time, Rogozin clarified, the organization will not completely abandon space launches - there is a space program that should be carried out, although most likely this will happen "in a truncated form."

“Our main goal is still to make money, and not be compared with someone else's technology. We will leave the launches, but we will not be considered a priority, ”added the head

https://123ru.net/moscow/265558481/

In the future, a fire on board an aircraft is guaranteed death, and when depressurizing, breathe, whatever is there, what is there from oxygen masks. But only if the plane's engines stop, it will fall, and the hyperloop does not have an engine as such, there are no spinning and rubbing parts under a huge temperature with tons of fuel on board and if something fails there, it will simply stop. And if a stupid pilot comes across who decides to put the son of Eldar at the helm, as we had, or fly around the storm front and dump 154 ​​into a tailspin, as again it was with us, then in the case of a hyperloop, the stupid pilot can only play a little with speed, more likely the whole pilot will not be at all

[Ded_Mazay]

Quote: Vol4ara

and when depressurizing, breathe, what is there, what is there from oxygen masks

Do you understand the difference between "atmospheric pressure at the echelon" and "vacuum in the tube"?
At sea level, the atmospheric pressure is about 100 Pa, at an altitude of 000 meters, it is about 10 Pa, the pressure in the hyperloop tube is declared at 000 (!) Pa. 26/000 of atmospheric!

Therefore, the maximum that threatens you in an airliner is loss of consciousness due to lack of oxygen. Even if the decompression of the board is explosive, there will still be a chance that the crew will retain control of the aircraft, lower the altitude and land it.
And if the same happens in the hyperloop, then this is a very big question - how will the attempt to breathe out of it end for your lungs ...

Well, for example: "how will the pipe section be limited", "how will the pressure equalization with atmospheric pressure be carried out", "how will the evacuation of passengers from the capsule in the isolated section be carried out", etc.?
In words - everything is easy, easy and simple, but in practice ...

As a result of research, one can come not only to a working system, but also to the realization of complete hopelessness or limited suitability. Little, you might think, there were developments in which they invested a lot of money, but everything ended in nothing.

If, in the end, the cost of a ticket for GL on the Moscow-St. Petersburg route will be 27 rubles, as calculated by the staff of the Institute for Problems of Natural Monopolies, then it is clear that there will be no Moscow-St. Petersburg hyperloop , since the trip on the "Sapsan" at the time of the study cost 500 - 4 rubles.

As the Concorde showed, speed is not important)) What makes you think that it will be safer than aircraft? At these speeds, any crash would be equal to a plane crash. Plus, the depressurization of the apparatus threatens a number of problems for passengers, from the fact that they will have nothing to breathe to barotrauma and decompression sickness.

Of course, speed is not the main thing, there is no main thing here at all. And safety is higher, because where there is no engine as such and fuel on board, safety is higher. The technology is as simple as a stick, only expensive, the pipe will be more difficult to make than the hyperloop itself. Most accidents on takeoffs and landings, there are no takeoffs and landings and there is no bad visibility and a pilot is not needed

It is not the height that kills, but the speed. The speed on this transport will be enormous and quite comparable to the speed of an aircraft. There is no fuel, but there is a vacuum. In an enclosed space at such speeds, a relatively small air pressure caused by the loss of tightness can lead to the capsule breaking off and colliding with the walls of the tunnel, which, if it does not lead to serious damage to the capsule, but can cause depressurization and instant death of people. Further, there are many more questions on the situational solution of certain problems. For example: if an accident occurs in a tunnel with a short distance, then filling it with air and sending the rescue team will not take much time (distance 25-40 km), if the distance turns out to be 100-500 km or more, the efficiency will be so slow that corpses will be removed from the capsule.

The vertical speed kills, and here it is equal to 0. To make a solid structure without wings and which is on the ground is much easier than the one in the sky. There will be accidents, but there will be less of them by a couple of orders of magnitude and there will be a chance to survive. There is no chance to survive on a plane when it falls

[Horon]

Vertical speed kills, but here it is equal to 0

When some aircraft crashed, the vertical speed was comparable to the speed of a parachutist, but it ended in tragedy! Even the firefighters and ambulances, who arrived on time, were unable to help. Accidents on the roads with fatalities are also the result of the impact of speed, there is no vertical speed either! It does not matter what the velocity vector is, it is important how it will be extinguished later. The higher the speed, the more difficult it is to extinguish it, the longer it takes to reduce it safely and the more serious the consequences of collision with other objects.

There the structure is about the complexity of a generator in a tractor. There is nothing to break there. the biggest problem will not be the capsule itself, but the pipe

[Horon]

The capsule moves at a very low pressure, close to vacuum, which means it will be necessary to ensure the locking and tightness of the capsule. Even a short circuit can become deadly, just like on an airplane. The two biggest dangers comparing this form of transport to aviation are the use of very low pressure and high speeds. Each of its use will be marked by a large amount of preparatory work and the intervals between flights will be almost like that of aviation when preparing an airliner. I am not saying that it is not possible, I am saying that it will be expensive, and the cost reduction is possible only by reducing security.

If something happened in flight, for example, an engine fire (which is not in the hyperloop as well as an open flame and fuel), then it is either a spin and death at once or an emergency landing at the nearest airfield with the remaining engines. If something happened during a trip on a hyperloop, it is a power outage, magnetic braking and depressurization of the pipe sluice. These are colossally different levels of danger, they did not stand nearby

[Horon]

If there is a fire of one engine on the plane, then the plane will quite normally get to the nearest airfield, no need to exaggerate. If there is a fire in the capsule, then first it must be stopped. At these speeds, this process is not fast and will take more than ten minutes. Further, the depressurization should be smooth, not shock. Shock filling of the pipe with air can damage both the pipe itself (process equipment) and the moving part and possibly cause injury to passengers. The pipe, it is also a pipe in Africa, will it be provided with emergency lighting in case of an emergency stop? How long will it take for the rescue team to approach the emergency site? How long will it take to evacuate passengers? Whatever one may say, otherwise it comes out. Everything becomes much more attractive if the pressure does not change, the speed drops to 500 km / h, and instead of a pipe, a usual fence. Only this is no longer Musk!

Braking by a magnetic field, no rubbing parts, no more than a couple of minutes. Raise from vacuum to 1 atmosphere in less than a minute. There can be no fire in a vacuum. There is nothing special to burn in the cabin. Providing fire safety is a thousand times easier than by plane. Do you hear a lot of fires on trains? this thing is many times more fireproof

[Horon]

Braking by a magnetic field, no rubbing parts, no more than a couple of minutes. Raise from vacuum to 1 atmosphere in less than a minute.

Yes, at least how to slow down! 2 minutes of braking is possible only if there are seat belts and it is not possible for passengers to move inside. Braking by a magnetic field still does not exclude heat release during the dissipation of kinetic energy. In less than a minute with large volumes, this is explosive de-meting.

There is nothing special to burn in the cabin. Providing fire safety is a thousand times easier than on an airplane. Do you hear a lot of train fires? this thing is many times more fireproof

There is always something to burn in modern transport. For lighting inside the capsule, you need at least wiring and batteries, for sure there will be more than lighting. Trains, or rather wagons, do not burn often, but there are plenty of cases. The cause is both human error and equipment problems.

So the safest is an airplane with an ejection seat, it has no problems even on the ground, eject at least 10 km, the parachute will open at a safe altitude.

This is a simple question, you will find the answer to it in the first link in Google. I will not quote, if you are really interested, you will find it yourself.

You have nowhere to go there, everything is already side by side, close by. And for long distances you will "wear out" vacuum tubes for it! The trip will be more expensive than planes.

[Blackmokona]

A number of companies and organizations believe that it will be cheaper

[military_cat]

The world's busiest airline is located in Korea (Seoul-Jeju). And the more passengers there are, the faster the investment will pay off. Trains can be more attractive than planes because they leave from city centers and do not require the strong security lines at airports. The flight from Seoul to Jeju lasts an hour, but at the airport it takes an hour to check-in, and it takes at least an hour to get to the airport (actually more) - you can save more than half of the travel time.

[loki565]

Rather, the security will be the same, plus will these pipes run on the surface or underground? if on the surface they are very vulnerable even more than the plane. If underground, then the price tag will be really cosmic. And time will be lost in the airlock chambers, where they will constantly pump and evacuate air.

The principle of such a vehicle, called Hyperloop, was developed in 2012 by Elon Musk. It is based on the movement of capsules through tunnels through an airless environment using magnetic levitation. This allows you to reach significant speeds, and the vehicle moves silently.

Dear Maskophiles and parishioners of the Church of St. Elon, Vacuum Train or Vactrain - proposed in 1909. And not just vacuum, but also with magnetic levitation.

Alfred Eli Beach demonstrated a model of a basic pneumatic subway system, in which air pressure in a tube pushed carriages, at the American Institute Exhibition in New York in 1867. Even the English-speaking aunt Vick in the description of Bichevsky's "Beach Pneumatic Transit" writes that the Musk's Hyperloop "does not fully implement" the development of Alfred Eli Beach. Those. the principle is over 150 years old. One hundred and fifty !!!
The idea of ​​a vacuum train was first publicly expressed in 1909 in a Scientific American article citing an unnamed reader. The reader suggested organizing movement of cars in a vacuum tube based on magnetic levitation. According to his calculations, the path from New York to Philadelphia (136 km) would take in this case 6 minutes 44 s, and the distance from New York to Boston (305 km) could be covered in 10 minutes 4 s. Subsequently, the unnamed reader became known as the American astronautics pioneer Robert Goddard. After the death of the inventor in 1945, prototypes of a vacuum train were found in his papers, moving at an average speed of 1 miles per hour (000 km / h). At the same time, the widow of the inventor Esther Christine Goddard applied for patents US 1 A "Vacuum tube transportation system" and US 600 A "Apparatus for vacuum tube transportation".
Here are the links:
https://patents.google.com/patent/US2511979A/en
https://patents.google.com/patent/US2488287A/en
And there was also the first practical experience of the Russian professor Boris Weinberg in 1911-1913, which resembles the Weinberg system, the application of the German Hermann Kemper in 1934. In its number - DE 643316C
Here is the link: https://patents.google.com/patent/DE643316C
In Russian, the name is approximately the following "Suspended railway with wheelless vehicles that move on iron rails using magnetic fields"
In this regard, the question is - what new principle was invented by Ilon Reeve Errolovich Musk? After all, if the old principle is not forgotten, then it cannot be reinvented. It can be used.

Musk only reworked the ideas and gave them a new sauce. There was a lot there, including the ideas of Soviet designers, which Musk issued as original, but in the use of which they found drawbacks associated with safety or imperfection of the technologies available at that time. How long will Musk's problems be resolved is still a question. This advertising genius may have decided to experiment immediately on people and preferably for their money.

Train Moscow-Vladivostok, Deep Way, N. Trublaini.

[Undecim]

The first idea of ​​a vacuum train on a magnetic levitation in its modern form was formulated by the famous American scientist Robert Goddard back in 1906.

Drawing from Scientific American magazine with an article by Goddard.
The world's first experiments with the movement of a body in a vacuum tube due to an electromagnetic field were staged in 1911-1913 at the Tomsk Technological Institute by the Russian professor Boris Veinberg.
His public lecture "Movement without friction", delivered in St. Petersburg on March 31, 1914, can be found at http://veinberg.o7.ru/vactrain/

[Avior]

In the "Deep Path" it was steeper - there trains self-propelled almost without an engine from Moscow to Vladivostok moved due to the fact that the pipe went straight, first accelerated downhill, and then went up the hill by inertia.

[Undecim]

Lem's The Magellanic Cloud (1955) is even cooler. There is an intercontinental train.

Here between parts of the world. Europe Asia.

From what you quoted, the investment was made in 2015-2017, 1-3 years after the company was founded. I think it was still an early stage.

Acquired in 2016 when the company went public (available on Wikipedia) - not an early stage anymore. I read the point of view that once you have placed your shares in a public auction, you are no longer a startup.

An IPO is going public, isn't it? Private companies can issue shares, but an IPO makes the company public.

Good point.
The first big money - 80 million was received not through an IPO, but a series of B round funding. Your post made me remember the difference. There really is no public offering of shares on the stock exchange.
In any case, round B funding is also the next level of business, not an early stage.

[Vadim237]

At one time in the Russian Academy of Sciences they said that reusable rocket stages are expensive and unpromising - but in reality everything turned out differently with this train it will be the same.

[KCA]

However, projects of various reusable launch vehicles were developed in the USSR, and in the Russian Federation too.
The construction of any hyperloops will cost as the construction of a cosmodrome with a dozen launch sites, and their maximum use is a non-stop way from the city to the airport, 20 kilometers.

[Vadim237]

Developed - just not implemented in practice, and so far there is not a single reusable stage or ship. These guiding hermotunnels can be manufactured on large 3D printers from the same composite powder materials as the bodies and parts of such trains in case of depressurization of the cars, they can be equipped with additional compressed air balloons to equalize the pressure in emergency situations - the only problem for these trains is the energy consumption to create vacuum along the entire length of the tunnel.

[abrakadabre]

in case of depressurization of the cars, they can be equipped with additional compressed air bolons to equalize the pressure in emergency situations

Their main problem from the point of view of safety is not the depressurization of the car, but the depressurization of the pipe.

[Vadim237]

This problem is solved by more durable materials, the tunnel does not collapse.

Thank you, you reassured me. At least in one question: do not hire go ... comrades, that is, engineers who are unable to calculate the strength of the pipe. True, there is still a list of questions for a couple of pages in small print. Both in the technical part and the economic part arising from it. Well, okay, on the main issue you reassured me.

And so, like any high-speed transport, it is a dangerous thing ... well, there are always enough people for the adrenaline rush.

In Soviet times, in the magazines Tekhnika-Molodezhi and Yuniy Tekhnik, similar projects were massively described and discussed! Stop making an icon out of a successful businessman!

[unaha]

You catch the difference between "discussed" and "implemented"? We are discussing a lot of things, what about the implementation ...

[Jacket in stock]

By the way.
They mentioned pipelines, why not use them?
There is a pipe, big and strong. Well, not a vacuum, but a pressure drop, the same version from the century before last.
Of course, a train for 100 people is unlikely to reach the speed of sound, but not necessarily all at once.

[Valeriy007]

This pipe will spit out someone with terrible force ...

[Operator]

Hyperloop will not take off - any hole in the train body under vacuum conditions means certain death of passengers from decompression. In addition, the residual air pressure is too low to create an air cushion to support the train instead of the wheels.

In the absence of high-temperature superconducting magnets, the real solution is to let the train pass through a pipe with atmospheric pressure, pump out air with a head fan, then use it to create an air cushion and release it in the tail of the train. The movement along the pipe is driven by a linear electric motor. The speed will be reduced to 800-900 km / h, but passengers will be guaranteed to be protected from decompression.

PS The Korean and Maskov projects are akin to the Chinese magnetic levitation train operated on the line between the capital's international airport and Beijing worth over $ 1 billion, which will pay off in a hundred years (like, so that foreign hamsters get jealous)

[Lord of the Sith]

Train to Busan)) Only fast

[Falcon5555]

Hyperloop is not needed by anyone except to show off.
If there is an accident, fire, depressurization of the train in the pipe - try to get out ...
Trains, planes ..., helicopters ..., buses with trolleybuses ... what else do you need - in terms of collective transport?
And as a result of Asian epidemics and the development of "information technologies", we may generally refrain from traveling or prefer personal transport - hello to Liksutov and Sobyanin. However, they provided themselves for their old age - at the expense of Muscovites - and they themselves do not take the subway. So - hello to Muscovites. As well as residents of some other Russian cities, where the authorities are struggling with personal transport with a tenacity worthy of much better use.
And in general, initially a completely different was called a hyperloop, as I understand it - something ring-shaped phantasmogoric for launching into space. There it is clear why the "loop". And where does the "loop" have to do with it? Musk just borrowed a nice word.

China offered to build cheaper with infrastructure, for themselves they are doing great construction.

You never know what China offers, everything is decided by the conditions, where are they?
1) How much will it build?
2) How long is the service life?
3) Will it withstand a magnitude 9 earthquake?
4) Will the ride be free?
5) Who will own the bridge?

After all, China offered to build a railway, but when they figured out the conditions, they realized that it would be suitable only for Ukraine or another colony.

And regret that Russian Railways does not build what you calculated in the note on VO.

I rarely agree with the comrade "Stroporez", but in this case I agree. Alas and ah. There is nothing even remotely similar in Russia, not even close. But still almost in the 80s, when the ER-200 was launched between Moscow and Leningrad, there was a lot of talk about the need to develop high-speed ground transport in the USSR. And they planned to launch at least FOUR of such directions. From Moscow to the South (to Rostov, and in the future to Vladikavkaz (Ordzhonikidze), from Moscow to Ukraine (to Kiev), From Moscow to the Baltic states and from Moscow to the Volga region. As far as I know, only ER-200 was operated on the Moscow-Leningrad route, and in the Volga region the train ran with speed limits, and the rest was not even designed.
And sometimes it was offensive. Around the same years, the Nauka publishing house published the book Urban Transport of the Future. Of course, such a vacuum train was not there, but the variants of vehicles and their experimental operation were described. And sometimes it was sad to read that somewhere at the exhibition we had a self-propelled sidewalk a hundred meters long and a monorail.
But such transport, even though it is expensive for the vastness of Russia, is the very thing. But alas, we do not have any land transport faster than the Sapsan, and is not expected.

Quote: zwlad

Do we need such trains? I think not.
The distances are not the same.

Exactly, not those. It is better, of course, a week in a compartment carriage (or even in a reserved seat) to cut from Moscow to Vladivostok, and not do it in 7-8 hours. Faster than a plane. With comfort and regardless of the weather ...

Quote: Antidote

If I don't need it, then no one needs it!
After all, it’s not on the couch, from the capital to the outskirts in 6 hours, you need, as grandfathers bequeathed, a week in a reserved seat, with bears and gypsies.

Yes, the Gypsies - it is unacceptable, and a few more bottles of vodka and a couple of loaves of "Doctor's" sausage

Quote: Alexander Vorontsov

Too many people go from the Moscow region to Moscow to work.
There are electric trains, and they are excellent. A swallow, for example, reaches the center of Moscow from Zelenograd in 30 minutes.
It is generally unrealistic to leave Balashikha - the whole expensive is one continuous traffic jam.
Expanding expensive ones is ineffective and in most cases it is simply impossible due to the fact that you will have to demolish everything that is built nearby.

At the same time, now the difference between travel by train and a car can be 1 hour, but this is not enough to outweigh the advantages of "personal space".
But if the time is not 30 minutes, but 10 or 6 minutes, the situation can change radically.

Even with current speeds, rail transport is becoming more profitable. In 2010 he was on a business trip to Moscow. It so happened that on Saturday I had to return. The comrade spent almost 5 hours on the movement of the "hotel-metro Yugo West" - a minibus to Vnukovo because of the continuous traffic jam (it was good at least the airplane was in the evening). I was advised to take the Aeroexpress train from Kievsky railway station. The specified time, if I am not mistaken, is either 36 or 46 minutes by the Aeroexpress to the nearest minute. The only difference was that on a minibus it cost, for example, 30 rubles, and on an Aeroexpress - 100.

And make them as straight as possible, or with a very large turning radius. On modern ones, it's not that this vacuum will not pass, but the same "Sapsan" will go at the speed of an ordinary train

For some reason I remembered how in Argentina they built a high-speed train "Tren Bala" - a bullet train, the money took the train, they were not built. The funny thing is that there are no simple trains either, all the rails have rotted ...

And I also remembered how the cosmodrome was built in Argentina, "in 40 minutes to anywhere in the country on a spaceship" they promised. The cosmodrome was not built, but the country got into debt head over heels, then the banks took all the money from people to pay off the debt. Then the horse militia chased people with clubs, it was fun ...
