- In this video Railways Explained team deals with the history of the idea of magnetic levitation, main aspects of its development, its application in modern transport systems and, eventually, we gave our best to give you the answer on how Maglev trains actually work.
But, first, what is a Maglev train?
Maglev can be defined as the system that enables a train to repel and push up off the track, while at same time enables that train to move in such elevated condition, taking the advantage of the lack of friction.
Due to fact there is no need for moving parts such as wheels and axles, Maglev trains have longer lifecycle, lower operating costs, higher energy efficiency, and, at the end, they are clean, quieter and capable of developing much higher speeds!
However, it was a long run for the science to make this even possible.
The key moment in the development of this technology was, first, the invention, and then certain modifications of electric linear motor, in first line those made by the 'Father of Maglev', prof. Eric Laithwaite. Prof. Laithwaite discovered new, special arrangement of magnets, in science known as the 'magnetic river', thanks to which a single linear motor became able to produce both lift and forward propulsion.
In order to explain the principles of Maglev trains, we had to indroduce some terms such as electromagnetism, superconductivity, electromagnetic and electrodynamic suspension, and many other.
PS. in the second part of this video, which will hopefully be released next week, we will present all existing commercial Maglev lines around the globe. Stay tuned!

I rode the maglev train in shanghai in like 2010, reaching 400 kmh was a good experience.
Me too. It doesn't feel like it's going fast at all :)
You need to thank Germany and the engineers of Krauss-Maffei, Thyssen & Siemens and the people of the Testing facility Emsland for that good experience. Oh, and 50+ years of development in maglev technology.
Dear rail lovers, we stated in the video that the investment costs of constructing a maglev system are 60 times higher than the investment costs of constructing conventional railways and 2-3 times higher than the costs of constructing a high speed rail. This information caused certain amount of comments, where this information was characterized as incorrect. After that, we did some additional research and found the following:
The investment costs of building the Maglev system are 6-8 times higher than constructing conventional railways and about 1.5-2 times higher than in case of high speed rail.
We must emphasize that there are certain HSR projects that are indeed more expensive per km than the Maglev system, most often because of complex topography.
The main reason why Maglev is more expensive is because the guideway’s and station’s construction costs depend very much on the alignment, primarily whether the guideway is constructed at grade, aerially or in tunnel. Maglev requires entirely separate rights-of-way, special facilities that are incompatible with existing systems. This results in substantially higher investments in downtown areas and in tunnels, due to its larger profile. In opposite, HSR can use existing tracks for some short sections in downtown areas where construction costs are among highest and achieve money savings.
Maintenance costs are sometimes claimed to be lower (or even nonexistent) for Maglev, but this seems to be an unrealistic assumption. Maglev has a significant advantage due to its lack of physical contact with the guideway, but any change in highly precise alignment would require extremely costly repairs. Moreover, very complex electronic instrumentation on the guideway and on trains requires very sophisticated maintenance.
Of course, we have nothing against the maglev system, the opposite, we are supporters of further development of maglev trains, having in mind its great advantages. In this video, we just tried to show the principles of its work and we apologize for unintentionally exaggerating the cost proportions.
Best regards from the Railways Explained team.
Break news search china naglev news which posted this week.
they still use magnetic to control direction, but super conductor which cool by nitrogen to lift the train.
Last October, scientists discovered a near room temperature superconductor (meaning no below freezing) being at least 15°c. This is important because this allow the conductor to be more function. I won't be surprise if maglev maintenance and construction be more cheaper.
@@loljewlol That is great news, thanks!
The start clips maglev train is in Shanghai China. Not Japan.
Meglev rails are more expensive to build compare to high speed rail, however maintainence and upkeep are cheaper than high speed rail so in long term applications it is better than both a high speed rail and plane as it is cheaper to upkeep and faster than high speed rail, yet holds more passengers and no long delays in airports compare to plane.
There's another commercial maglev service in Changsha, Hunan Province, China. It's a slow one running at 100kph, much more stable and quieter than wheeled metro trains. The service runs between the city's South Railway Station and Huanghua Airport.
Meanwhile the one in Shanghai has a lot of vibration because it's outdated and fast.
Something tells me I found the Wendover Productions of Trains and Railways and you know what I am all for it.
German maglev (TR09) compared to HSR
These are advantages in favor of maglev
● Low operating and maintenance costs
Respectively 40 and 60 percent lower
● Lower energy consumption at 300km/h
● Lower noise level (through towns etc.)
● Small footprint from the elevated track
● Less material consumption. Low weight
● People, animals, infrastructure and
waterways pass safely below the track
● Farmers fields are not split by the track
● Better for the environment. No heavy
metal emissions from the track, nor any
weed killers needed to control foliage
● High top speed (500km/h, not 250km/h)
● Rapid acceleration means more stops
● Better curve characteristics (radius)
● Climbs hills of 10%, not 4% as for trains
● Flexible adaptation to terrain/buildings
because of these characteristics
● Fast construction. Predictable economy
● Construction cost is 25 million USD per
km which is lower than elevated HSR
● Reduced need for bridges and tunnels
● Higher reliability and punctuality
● Greater benefit to the community
● Automatic mode and speed adjustment
● High voltage cables & fiber in guideway
● Provides daily commuting between cities
and towns aiding decentralization.
500 km in 1 hour. 4 minutes per stop.
Can ease the pressure on often very
high house prices in central areas.
● Full separation from slow-moving trains
● Releases capacity on existing rail to
freight and local traffic trains
● Carries goods (air freight containers)
● Redundancy with conventional trains
● Snow is blown away and off the track
● Can replace most domestic flights(CO2)
● Avoids the transportation to and from
airports as well as check-in, security and
associated queues, both ways
???? Is it even running?
@@qjtvaddict I would say that high speed EMS maglev (T-shape) is running, yes.
Great Video Presentation of MagLev Train Technology! The many advantages of this cutting edge technology like low maintenance, safety, efficiency, clean, green, and pollution - free transport system is a clear indication that we can develop faster and energy - efficient train services, in a safe manner. Well Done, Keep it Up! Can't wait for future updates, part 2.
Much higher speed and expensive? Not necessarily. China build a lot of low-speed maglev running at 30-40km/h with a top speed less than 100km/h to take advantage of the low-speedness and cheapness of maglev.
We agree. Low speed Maglev system is a different story. However, we don't believe it will help us solve our tranportation issues and needs at long run.
Railways Explained Why not? They are cheaper to built than subway, having a better acceleration. I'm kind of optimistic that in the near future we can convert all conventional subway lines into maglevs.
High-speed maglevs are monsters. I don't think they're going to be cost effective in the next ten years. I believe right now the work to be done should be build a lot low speed maglev and test a lot high-speed maglevs. A severe disadvantage of maglev is lack of international standard, making significant obstacle to future international travel.
High speed maglev and low speed maglev cost about the same. Its a myth that highspeed maglev is super expensive
Its low speed maglev cheaper to built than regular train?
I've been looking for a channel like this one. Keep it up!
Get to the chopper!!! Thanks for the video, very clear and informative. Cheers mate

Thankyou sir.
for given this very important and very interested explaination 👍
Maglev is the future. Expensive to build though
You really worked out to make us explain
Good video-Thank you
In the 21st century there are a few countries using powerful electromagnets to develop high-speed trains, called maglev trains. These trains float over guideways using the basic principles of magnets to replace the old steel wheel and track trains. 7:51
Japan's L0 Series Maglev is the fastest train in the world, with a speed record of 374 mph or 602 km/h.
Whereas Maglev trains travel at speeds of up to 400 or 600kph, bullet trains travel at a modest 320kph.
Yet high speed is just one major benefit of maglev trains. Because the trains rarely (if ever) touch the track, there's far less noise and vibration than typical, earth-shaking trains.

Hey I found your channel through Simply Railway. I love train and I love your channel, very educative. However, I noticed you didn't put the video/graphic source you used in the video. You can put a text in the bottom of the video saying "courtesy of.. " or put it in the description. Can't wait for your new content!
Great Explanation
OK I subscribed your channel you are awesome
In general, the idea of designing all magnetic trains is one of the inventions of Professor Eric roberts laithwaite .
Hermann Kemper. Eric Laithwaite just invented the principles. Hermann Kemper put them all together and patented it in 1934. The father and designer (one of them) of todays maglev systems in use - especially the transrapid - was named Hans Georg Raschbichler, he practically invented this system and evolved it to serial readiness. Another inventor/designer/engineer connected to the transrapid and lower speed maglev systems is G. Steinmetz. Lastly mentioned build the first high speed maglev train in the world, the Transrapid 06 (i guess together with the second man).
Nice video once again
great channel...
Explain with mathematical timing data for each classification of train with respect to galactic weather and to spacecraft travel as well
Maybe the two fundamental track structures can be combined into one for the most sophisticated system and the utmost precise quantum efficiency.
my left ear loved this
i kinda understood 25% of the content. lol maybe ill understand more if i watch it again and again.
The first place I ever heard of a maglev was in the fourth book in the Uglies series Extras. Since it was a semi sci fi book, I assumed it wasn’t real.
Does Railways Explained plan on doing videos about transit oriented development and other types of train like metro, light rail or trams?
Are the superconducting magnets charged by dc or ac current? I know that it maintains a DC current after being charged, but I'm confused on the exciting current that charges the superconductor to begin with. In other words, does alternating currents have anything to do with SCMaglevs?
MAGIC ! LEV ! WILL ALWAYS ! BE !! TOO !! COSTLY !! JUST !! MORE !! SMOKE !! IN !! PIPE !! DREAMS !! BY !! THE !! INVENTORS !!!
Very good video 👍
EMS uses attraction force right. Under the train do they attracted or having a gap between guideway and train under-carriage???
The gap is at about 10mm (+-2mm).
"is the fact that maglev reqiers rare earth metals"
That is not the case for TR08 and Linimo. While it is the case for TR09 and L0, the amount of rare earth is not that much higher of a conventional train with synchronous motors, like a ICE3 or Velaro platform train.
At least Brazil is missing from the country list, possible a few more.
It is only mentioned in the context 'to be considered'. And yes, it is primarily related to superconducting maglevs.
And for Brazil you are right. We said this topic was a novelty for us. :)
In 2017 they opened a test track in Rio De Janiero, 200 m long. But it's not a full scale prototype yet and still not certified, right?
@@RailwaysExplained
I dont know if its certified yet. But considering ussr and uk was mentioned. The first that had one barley working prototype that was just active for 6 month, and the second having only one peotitype that well was runing for a fe yers, never past the earily prototype level. i would consider brazil above them in development.
Intrestingly korea, china, japan and germany all developed both high speed and low speed systems, while usa devloped more freight
Feals like im still missing a country...
@@RailwaysExplained The TR don't use rare earth metals or super conducting.
Therefore no cooling is nessesary.
In the way you presented this in your video that's not understandable and therefore - sorry- simply wrong!
Greetings from Germany,

@@DB--lv6tt The transrapid is the better high speed maglev system, since it doesn´t need to run on wheels up until it reaches floating speed. It floats from 0-600km/h. The Germans abandoned on the EDS in favour of EMS already in the seventies (Erlanger Erprobungsträger EET01), the result is the Transrapid which can today be seen in form of Shanghai SMT/Transrapid 08, and CRRC CF600.
@@bieneulm1982 Hallo Daniel,
warum verschweigst Du den TR 09? Nur weil der neue chinesische maglev eine Kopie vom TR 08 alias Shanghai maglev ist?
Der TR 09 bekommt die Energie nämlich ab 0 km/h berührungslos, und hat keine mechanischen Kontake mehr wie der 08 und der "neue" chinesische maglev.
I have ridden the Shanghai Maglev in 2017.
Can you make a detailed video about the TRACKED HOWER TRAIN. Why they're not a challenge to maglev, despite being cheap to build and run.
But how would EDS maglev switch or change tracks? Are they supposed to be able to do something like that?
Samo napred!
What are the KM cost per KM compared with a plane ?
Nice
Realy I like this video
KISS. Keep It Simple Stupid. :)
Awesome and well thought presentation. Thank you for sharing and educating us. Happy New Year. May year 2021all of us see this awesome channel will keep growing and growing.
Can't wait for the next video about commercial aspect of Maglev trains. Especially the Medium-Low Speed Magnet e.g Changsa and Beijing S1 line.
Thank you for your kind words! Happy New Year to you as well!
Great
Why nobody mentions theoretically limitless acceleration of maglev trains? With cheap energy in the future, such trains will be able to stop much more often than conventional high speed trains.
Considering the expense of the CAHSR we in the US are better off just building maglev as HSR anyway we are so bad at HSR that we won’t save much or any money compared to maglev and we also have our own rare earth materials so we can create the trains or tracks domestically.
How can we achieve immediate braking of maglev trains in case of emergency?
Change direction of the linear motor i guess.
Either way, it stops much faster than a conventional high speed train.
Just turn the magnetic poles that means to flip the switch + to -
How would u reduce speed to stop momentum?
so there is gap between train and track??
The EDS maglev train is levitated by the repulsive force between the same polarity, but where are the magnets? are they at the bottom the train? or are they located on the side of the train?
The magnets are located around the track underneath the vehicle and pull the train to the stator (Tragmagnete). On each side there is magnets that push it away to keep it from colliding with the track (Führmagnete) and to maintain the correct position on the track.
can they be coupled units though?
not unless specifically designed for coupling. but at those speeds you can run them individually with higher frequency. Consumers will prefer that.
I am interested in the differend concepts for switches. because I think those are a major issue.
the new maglev trains will reached 800 km per hour
You are only going about 268mph which isn't bad considering the speed limit on the highway won't let me drive my car that fast.
nice nice
So this is what Vladimir sounds like
so they built electromagnetic coils along the tracks and have to control every single of them hundreds of kilometers? and do the train carry liquid nitrogen to cool the superconductor?
Amtrak maximum speed is 65 MPH which is pretty good for USA. China rules. That speed is awesome. Only China can do it. Well done China..
Fake information, yes China has faster rail, but Amtrak is not limited to 65 mph, infact most Amtrak train routes are set at 80mph and actually go up to 160mph. There are several routes under construction that can reach speeds up to 220mph. China has a great rail system, so why lie to try to make it greater?
the maglev train can go 1200 km per hour in a hyperloop.
Can you make a video about the Bangladeshi high speed railway project.please?
Could you share with us a few details about that project?
Wow… so many options.
I recommend you to watch free documentary CZcams channel on maglev train.
there ist a New System in Germany on Planning. its from the Company Max Bögl. They using an other form vor the Levitation
which is better this or hyperlooop?
Hyperloop doesn't exist so this
@@Bohh574 it is possible if highway will become maglev?
China's Guangdong government is in "preliminary planning stage" to construct 2 high-speed maglev lines: Shanghai-(Shenzhen)-Guangzhou and Beijing-Guangzhou-Hong Kong/Macau. The new maglev lines will cut travel time from Guangzhou to Shanghai to 2.5 hours. Meanwhile, Guangzhou to Beijing will require just over 3 hours, halving current travel time by high-speed rail, according to Shanghai Daily’s Shine.
www.shine.cn/news/metro/2102224928/
China has already abandoned these plannings.
Wouldn't it be much easier to change the polarity of the magnets on the train, rather than changing the polarity of the magnets on the tracks?
Could imagine this were much cheaper in production and therefore more attractive to build.
Easier how? Do you have an idea for it?
thats what Japanese did
Why don't we have this in America

How many of the passengers want to slow down and look out the window? Is it actually more efficient being fast? Tell me.
Yes, especially for intercity travel. The highspeed will allow one to work in one city while living in another. This can bring down real estate prices as people don't have to be crammed in the city.
@@xirsixussien7303 Do you know the price per mile to build a maglev to train? It's very expensive?
USSR 😯
Felt so different
Afaik their energy efficiency is lower than that of conventional rail.
Also disadvantage is that they are not interoperable with anything and need elevated ugly tracks
How come India is not studying maglev train technology?
"there main disadvantage is higher construction cost"
Sorry, citation needed. People repeating this like its some kind of religious scripture, but nobody every source it
60 times higher? Are you high?
Looking at HSR rail projects in Europe they vary from €15M/km to about €60M/km. But when looking closer to it, pretty much all of the sub €25m is really old projects, even correct for inflation, the cost of new rail have outrun the inflation rate quite significantly. This leave us with a range from 25M to 60M per km of double track the last two decades.
When looking closer the amount of structure is pretty much directly correlated with the cost. €25M have structure in the single digit percentage, and 60M is closer to 50%
There is no high-speed project in Europe with structure much higher than 50%, but there is plenty of other projects. "city track" project in Stockholm for example have a structure of about 95%. That project is a eye watering cost of €270M/km.
Looking at base price for non high speed track with 0% structure they are about €5M/km for single track non electric, 6.5M for electric single track, and about twice that for double-track.
A comparison is also unfair because a low speed track between point A and point B is often much longer than a high speed track. There is two different reasons for that. Low speed tracks tend to go around obstacles. And high speed track can have a higher inclination, allowing them to pass over hills (but not mountains)
Shanghai maglev train cost about €1.1B and is about 30km long. That would imply that the km cost was about €37M, adjusted for inflation, about €45M and Chou Shinkansen in Japan is calculated to cost about €110M/km.
Is high speed track much cheaper in China than Europe? Well sort of. The build cost spans from about €14M/km up to about €45M. Adjusted for inflation is about 17-55M. Already here the 3-4 time narrative breaks down its more of a 0.8-3 time number.
But there are issues with the number. The 14-45 range include 200km/h track that China calls high speed tracks, but would not be the case in Europe. Remove those and the range is 22-45 in stead.
There are more issues. Shanghai maglev track is actually not 30km, its the line length that is 30km. The total length of track is about 70km, equivalent to 35km double track. The reason for this being about 1km of back track at the airport as well as 6-7 km of depot track, including 600 meter of triple track at the depot. Apart from that the total system cost also included 15 waggons, $10M/pice. One depot with spare parts, about $30M, Two station buildings, about $50M/each, and a C&C center and training, about $20M. Sum that up is about €300M of value that is not included in the other projects. High speed rail is always costed with out vehicles or depot. Also station buildings are generally extra. Even if that would not be the case, the very short track make the station buildings a realtivly high cost.
The total cost for the track (as well as the electronics) is about €800M, and that for 35km of equivalent double track. This put the cost down to about €22M/km. So even comparing with other chinese projects, this put maglev actually on the cheaper side of HSR, not the more expensive side. And that is still comparing a 430km/h track to a 350km/h track.
So then, what about the Japanese Chou shrinkage track. Why is it so expensive. The reason is simple, its 85% tunnel, and about 95% structure. Compare that to "city track" project in Stockholm, its a bargain.
Damn very good research and explanation
First of all, a bit of decency would be appreciated (that goes for the 'are you high' part). Indeed, you seem to be familiar with the topic, and as such, we would like to have you here more like somebody who shares the knowlegde with the community, than somebody who only provides a critique for the sake of 'being right'. That said, regarding the answer, more or less you are right.
As with any line infrastructure project, the main cost driver that affects the cost of construction is the terrain topography and the type of solution that needs to be built for the system to be functional. The proposed Chūō Shinkansen MLX maglev in Japan is estimated to cost approximately US $ 82 billion because 80% of the route are tunnels through mountains. Correct.
On the other side you have China who aims to limit the cost of future construction of maglev line to approximately US $ 25 million per kilometer.
But, when we said "their main disadvantage is higher construction cost", our main motivation was that not every country can afford a maglev system. How much would a maglev cost if technology is exported rather than developed localy, for example from Japan to Australia. Since only Japanese companies 'know' how to build, Japanese workers and technology have to come to Australia. Also, the most systems and components have to be manufactured in Japan, then transported and installed in Australia. When you include all of that, our estimation is that current maglev construction costs would be increased by at least 30%. In other words research also costs. A lot.
According to available data, average 1 km of maglev tend to be more expensive than average 1 km of HSR. That led us to the conclusion that we put into video. The issue is only with the percentage, it is indeed exaggerated in our video and may only relate to extreme cases.
In any case, we really appreciate your explanation! That is the main idea of this channel.
You seem to be some expert on maglev trains. Well done. The Railways Explained team argued at first that the preparation of the video was challenging, and that they did not encounter this topic. I think this is one of the best videos on You Tube about maglev trains. Railways Explained fantastically explained this topic.
@@RailwaysExplained
Common decency would be to check up basic facts before making a video.
I would say that topographic being the main cost driving factor is a over-generalization. Its really mostly true where its actually the case. In something like Washington to Baltimore its land value that is the main driving factor.
" The proposed Chūō Shinkansen MLX maglev in Japan"
The current status of Chūō is under construction. And MLX is the last generation prototype trains. The system name is SC-maglev.
"our main motivation was that not every country can afford a maglev system"
That is also true for HSR, but the cost benefit factor of maglev is generally better than of HSR. That might note be true in all nations. Nations with very low wages might note befit from the decrease in manpower needed. HSR is also not a monolith. There is huge differences in ICE4, ICE3 and CRH380
"Also, the most systems and components have to be manufactured in Japan, then transported and installed in Australia"
Most compoents like Trains and power electronics. The track and the magnets is produced locally with shipped in equipment.
" our estimation is that current maglev construction costs would be increased by at least 30%"
Why would that be true.: if that would be true for Japanese maglev built in Australia, it should also be true for German maglev built in China. And if that would be the case, it would totaly break the economic theory around it.
@@RailwaysExplained
"According to available data, average 1 km of maglev tend to be more expensive than average 1 km of HSR."
Where is that data.. source it.. I never seen it. I worked with maglevs for 10 years and i asked every time i seen the claim. i NEVER seen it. In pretty much every case its based on unequal comparisons.
Also.. even if it would be true. its not even close to 3 or 4 times. And the 60 times.. is just wrong. That would imply that HSR is about 20 times more expensive than regular railway. I bet you even can find one comparisson with a full standard electric railway that cost 20 times less than any selection of HSR you might find. Even the California one.
"In any case, we really appreciate your explanation! That is the main idea of this channel.
"
No problem.. next time you see something like.. "60 times more expensive".. maybe you should think... well this sound unreasonable high

@@quantly you photocopies are everywhere.
I think the Chinese maglev does not have sufficient clearence to go 600km/h or even faster in a pressure reduced atmosphere like a plane.
The current one in Shanghai can not. The materials used to build the train would not sustain that speed and will come apart. After all it was build like 15 years ago. But there are two parallel developments in China. One is the conventional meglev, which is the thumbnail of this video. The other one uses high temperature super conductors, which doesn’t require electricity to stay afloat. Both now all passed engineering sample period and already have a functioning train. The only thing left for them to do is to build a track long enough for both of them and run tests and collect data. Both of them runs at 630 kph.
It will, if the track will ever be started to be build and somewhen in the future completed to, run at a regular speed of 450km/h, that will make it at best 20km/h faster than the Transrapid in Shanghai. 600km/h is just propagated through media "to make it look nice" since every transrapid system is at such high speed to energy-consuming. The ideal and energy saving speed for the transrapid is at 300-450km/h, this goes for the one blue Transrapid-Variant (CRRC CF600) in China as well, since it is basically about physical borders/limitations. The German versions Transrapid 07/08/09 were already capable of 500km/h+. They chinese showed up around the year 2000 in Germany and wanted to make a contract for Shanghai, back then they ordered the German engineers "the transrapid must be made capable of reaching 500km/h at least" to make it worth being introduced to China. Up to this day, only the German build Transrapid 08, in service as Shanghai SMT, could reach over that border. To not lose face before the world and the inventers of this technology they propagate the 600km/h which can up to this moment only be simulated, due to no track being available that´s long enough.
@@bieneulm1982 You are correct in atmospheric pressure but I am suggesting an 11psi single tunnel

In democracies sometimes it is cheaper to go underground with a number of modern multi modal TBM working 24/7 than have expensive court cases.
A single 11 psi Maglev tunnel can increase speed from 600 km/h to 700km/h while still being breathable and passing stations would allow daytime trains to stop where needed with overnight container trains beating any truck by eight hours over 1,000 kilometres between freight sidings eliminating daytime planes and reducing trucks.
Using Sydney to Melbourne as an example with passing stations at Canberra and Albury it would cost $60,000,000,000 and return $20,000,000 per night which makes it able to subsidise daytime fares below planes and still have a return of 10%
Perhaps cooperation between Japan, China and America can develop the maglev container train with Australia to use an international guideway to benefit the world.
Maglev vs bullet train what is better?
@Karym Eliya yes but what is good and better.
@Karym Eliya what is better and faster and need to build
@Karym Eliya OK
Id say maglev if it was built today because the bullet train needed completely new infrastructure because of different gauge so the extra cost for maglevs would not be as much
@@the_retag Humm intresting point
It’s either/or

Low Sound level😌
If China can build a maglev system, why can't we do it here in the US?
Just like China, we have a fiat currency so it shouldn't be too hard.
because in US something else than the dollar does not count and therefore everything is corrupt there
please spanish thanks you---------por favor en castellano tambien gracias.....
También agregamos un subtítulo en español.
I am actually curious to hear your Spanish with Russian accent.
@@GyacoYu it's not Russian. It's from Balkans. 😊
Railways Explained 👍
Railways Explained The Slavic Balkans? Or Greek? I thought I could tell the difference between a Greek accent and a Slavic accent but maybe I was wrong.
This is the perfect maximum speed human being can tolerate in their own sense. More than this speed is possible in Intercontinental connections only. Inside a country this speed is enough for fulfilling current needs. Super China. With this speed everyone can enjoy the natures of China.
This guy talks like Tricia Takanava from family guy
Why America doesn’t have high speed train?
That's actually a good question, and we are planning to deal with it in some of the future works :)
The government dont ha e budhet for infra.. They have budget for wars in many smaller countries
En Venezuela se han hecho estudios y hasta se hicieron modelos a escala y con buenos resultados lamentablemente no hay voluntad política ni capacidad financiera
