Fun fact: Despite being in service for over 50 years and servicing billions of riders, no Japanese Bullet Train has ever had a major injury caused by operation. The countless safety measures and amazing engineering have given them a quite impressive...uh... track record.
I see what you did there..... Nice
: )
Until Kyushu incident happen
Fun fact France has faster trains now
@@harryvlogs7833 Because the French were experienced at locomotives than the Japanese, the Japanese had to visit France to find out how the French engineer their trains to make it go faster, and then the Japanese were like you know what? Let's make our high speed train and better.
Nothing but respect and admiration for the Japanese engineers and scientists.
and now let's see how fast it gets 'round our track...
haha!
Which, of course, means handing it to our tame racing driver.
Some say...
@@samarvora7185 he can stop a bullet train
with his toe.
@@centuriongaming1868 All we know is... He's _not_ the Stig...
😂😂😂
At least it didn't catch fire like May & Hammond Rail
Fallen7Pie one of their best episodes.
lol!!😂
🤣🤣🤣🤣🤣🤣🤣 i almost dead 1🤣🤣🤣😂
which episode was that?
James, your train's on fire.
Thank you for your interest in Japanese bullet train. About 150 years ago, we Japanese have learned railway technology from UK. I'm very happy to cooperate with your country again installing new high speed train Class 800.
I only watch documentaries because Hammond is on this
me too
Same haha
Yeah he’s got that informal voice !! Plus he’s funny too
Qasim Chaudhary You twat ! Bet your Gay ya twat ! Get a life
Qasim Chaudhary what the fuck
Just got back from Japan and my God what a marvel of a country. The Shinkansen is an engineering miracle
Richard Hammond has a wonderful voice. Wtf. Also he's a brilliant, brilliant presenter. He reads and speaks so very well, damn.
Oooooooooooo well hellow
“Hammond you idiot”
-Jeremy Clarkson
good presenter,but also a racist,narcisistic sob
@@georgeionescu6425 simply acknowledging race exists is enough to get you called that today. Stop being such a perpetually offended little shit.
@@georgeionescu6425 Shut up man
Brilliant documentary. Only thing missing is Clarksson commenting on Hammonds failures. :D
HAMMONDDDD!!!
Hammond you blithering idiot!
"Hammond you idiot..."
16:40 He said that from 1500-3000V it increased to 25,000V. That's not as simple as increasing the volts. They also change from Direct Current to Alternating Current. Most commuter lines use 1500V DC. The Shinkansen uses 25kV AC.
The Shinkansen is truly a marvel of modern tech. Having traveled on them numerous times, they never fail to amaze.
Just a pity Mr Hammond, like so many other TV presenters, cannot pronounce "kilometres" correctly.
Is it because they're British? lol
Speaking as a British person, he’s saying it correctly, isn’t he? That’s how everyone seems to say it over here. It’s kill-oh-met-ers, I’m not sure how else it could be pronounced, unless you were expecting “Keel-oh-meet-ers” or something.
@@adamdzwoniarek3841yes, that’s exactly it.
32:42 that look on the engineers face sitting by the window is just priceless. LOL Shows what the relationship is between Japanese managers and engineers in a odd situations...
This guy teach better than my teacher
You should watch top gear, he’s on it, it’s by far the best show ever
He was
@@cj_r3249 Good show,I've some of it before
Anyone else in love with that second bike and sidecar combo? The leaning mechanism is very cool.
"wobbling along a dead straight track" that track is more bendy than James Charles...
Brae Jordan G-CDJK hahahahahhahahahahhahahhahahahahahahhahahahah
Dead straight by UK standards!
@@howlingwolven Regular passenger UK trains go 80mph as standard. Thats some unused track they are on and fairly flat. Second set of wheels went on no bother.
Never mind the thing put there to derail it on purpose.
Fantastic documentary" I need to watch more episodes of this series. This just goes to show you how much engineers today rely upon problems solved centuries ago.
36:10 "And every 100 years or so, Tokyo has been shaken by an even more devastating quake" Its kinda disturbing that this show came out in 2008. Imagine watching this on the day it happened.
Hey
This was Season Three so it was filmed around 2010.
@@EamonMYT and a year later the biggest earthquake and tsunami happens
Fun fact: indonesia also has a Devastating earthquake every 20 years, last time it happened is in 2019 in Palu and around 20 year or so theres the 2004 Aceh Tsunami (yes i know its not perfectly 20 years but you get the idea)
Out of the TOP GEAR guys, Hammond was the most hilarious of the three, but James May's laugh beat everything.
What in heaven did he wear a helmet with goggles for?
@@valeriosalvador6810 in case a train falls out of the sky onto his head
I'd be so happy watching any documentary narrated by hammond may or Clarkson ❤
I've watched documentaries from all three of them and they're all fantastic presenters.
Actually leaning into the corner doesn't reduce the centrifugal force, it just shifts your center of gravity in line with your new resulting force (gravity + centrifugal), meaning the (attempted) movement vector of your vehicle is towards the ground, with no other directional component. TLDR: You just adjust your center of gravity to make the centrifugal force go completely into the wheels, instead of toppling your vehicle. It still exists though.
4:30 - Voiceover: "Dead straight track." Picture: Curved track.
"It's is by my reckoning 112 wheel drive." I love that sentence. I"'m so confident I'm going topless." I love that as well.
“The stopping is going to be uncomfortable” he says as the prototype destroys as it rams into the end 😂
I enjoy education system that is informative, encouraging and entertaining. Thanks for great effort to share knowledge in such fun and inspiring way.
my brain grew 2 sizes after watching this.
Thanks for an interesting, entertaining and educational programme. I really enjoyed it. Bless you and yours.
I love this guy. 😍 and the content. So full of good infos. 😍😍🤯
50 minutes and nothing about the nose preventing tunnel boom :(
Unicorn Cycling I thought the same I was looking forward to that
I don't get it. If you guys already knew that's why the nose is designed like that, why were you so strongly anticipating hearing "Hamster" tell you about it?
@@NovejSpeed3 So that everyone else knows it too.
well I read this comment and now I do
Tunnel boom?...its not travelling at the speed of sound!
Leaning into turns does not reduce the centrifugal force. Rather, it merely shifts the center of mass.
Justin Case that and the fact that “centrifugal force” is not a real thing, rather a velocity acting at a tangent to the centripidal force. If the so called “centrifugal force” existed, then every time a hammer thrower released the hammer at the point where they released it (90 degrees from the intended direction of travel) then it would just bugger off into the safety net.
thank you
also, @@lachlanwoodsmith6064 of course it is not a "real" force for us that use an inertial frame of reference, but for a frame of reference that moves with the carriage it is very much "real"
you could say the same thing about gravity, it's all a matter of perspective
Proud duck.....c'mon guy.
I just tried duck idiots perspective on gravity. It's definitely not my perspective...when I jumped...I broke my leg...
It was real. Other ppl saw it..not just my perspective.
Almost 60 years of service no fatal victims in the shinkansen... Awesome record!!!
And only with an has an annual average delay of 6 seconds
Used to love watching this series after school :)
this is why Hammond is my favorite of the Top Gear guys.
hes just a regular engineering nerd and loves looking at how things work.
James May Enters the Chat
How could they have known the prediction of that massive and devestating earthquake looming over Japan made in this programme would come sooner than later on
2011 as the largest earthquake in recorded history..
Harry yeah this aired June 2011 and no doubt was filmed prior to the Japan earthquake and resulting tsunami in March 2011.
@@Patrick94GSR It's kinda incredible that it happened not long after this was being filmed...
36:25 that's very true. 19th September 2017, a Mexico City Subway train derailed during the deadliest earthquake in my country since 1985
what a beautiful train, the science is awesome, thanks.
Richard Hammond’s voice is the most recognizable voiceover in documentaries
Ey Danish-kun
Jendogs said your a liar as David Attenborough is the most recognisable voiceover in documentary
One thing not mentioned about Asaka, was it is believed the driver oversped the train through the turn to make up for the fact he was late and been essentially already written up once that day. Not soooo much engineering failure as much as operator failure.
Yes, you are correct on that point. However, the driver in question had also done a "course" which was, in my mind, designed to humiliate and belittle and this made him very bitter and determined not to be late again. So it was the culture of the rail company that caused the accident as much as the driver.
46:36
Richard: Hello
Japanese bloke: *speaks japanese*
Richard: Yes. Hello
wow
classic British tourist. let the man speak his funny language and pass it off with standard remarks
I didnt catch what the japanese man said first, but when he went to shake hands he said "Nice to meet you" then "come in"
Edit, I think the first thing he said after slowing it down was "we are *name of what they are*" could be wrong though.
Or it’s just a bit of comedy for a documentary u simps
He was saying nice to meet you at the start.
@@danadezza I'm British too btw. and that's a blatant misuse of the word simp >:(
this is frickin amazing!!
I have to say.. that second side car is so cool
Didn't realise it had only one wheel... mind blown!
Great video and No ads makes it great.
DALE BECK lucky you, I’m infected with ads
None for me either.
22:00 i can hear Clarkson shouting "Nonsense ! POWEEEER !
It has been two hours since I’ve seen this series I need to watch it again
A Class-A Documentary! Great work!
21:34
Dodge: That's where you're wrong kiddo
My home state of California is currently building America's first and so far only true high speed rail line, that'll one day connect San Francisco and Los Angeles in under three hours. Like Japan's Bullet Train, it too will employ a similar early earthquake detection system. Despite setbacks and cost overruns, not unlike Japan's first bullet train line that cost twice its original budget, progress has been moving at a steady pace for the past several years in California's Central Valley, and will one day extend into SF and LA.
for sure they will go over budget
@@wilfredprins9718 name a major infrastructure project that hasn’t, especially one of this scale in a place that’s never built it before.
Granted that shouldn’t necessarily be an excuse for the higher price tag, but when comparing it to what we have now (driving and flying) and the alternative being continuing to expand freeways and airports at an even higher cost beyond just financial, high speed rail is the better long term solution.
@@ChrisJones-gx7fc you were writing "not unlike Japan's first.... costs twice it's origan budget"
I'm sure that the budget for a train in the USA will go over budget, the only way it will not be twice the budget is when the original busget had allready a minimum 80% extra incorporated into the number that was calculated
@@ChrisJones-gx7fc in the Netherlands we have in Amsterdam the noord zuid lijn(north south line) subway
it doubled budget
also we had the betuwe route, cargo train to connect the harbor or Rotterdam to Germany, calculated on 750 million guilders (about 335 million euro)
total cost when finished, slightly higher at 4.7 thousand billion euro...
Very informative and educational indeed !
I like this guy because he explains each and every thing.
From the information shared in this piece, I can only assume that the trains in Melbourne, Australia have the first example of conical wheels and no spring suspension. I take this assumption from the fact that every evening after work on the train home via Richmond, I watch as people are thrown about the carriage, even though we're going no faster than 50kph, and also watch the carriage connections sway about wildly from side to side, looking as though they will become uncoupled.
Yet when I travel on the German S-Bahn, Regiobahn or high speed ICE (Inter City Express) trains, they are smooth as silk..
Australian trains are pure garbage, had similar feeling on Sydney ones.
Australians are tough masochists ; no smooth as silk for them . Bring on the broncos .
Just to be clear, springs by themselves do not dampen, the coil-damper unit dampens motion.
Wow what a great documentary thanks man
Amazing work done on this video
first cartridge derailed because it hit the asphalt lol
I noticed that too. Plus the track isn't even straight!
brankobruda I emptied my cartridge while watching this
Beyond that, they change the wheels AND they put weight on in order to test the performance of the new wheels. A child would realize that you aren't really getting information of ONLY the wheels performance with that. How is that grown ups are able to accept that as a valid experiment?
@@acampoverdeify And it's on a different stretch of track
AF Gaming Lmfao 🤣 hahah that one got me. I could use a new cartridge myself now that ya mention it.
I have been all around Japan on these, and they are amazing!
I am also disappointed you didn't call it a Shinkansen as that is the name.
Great documentary!
You forgot to mention why the nose of the train is that shape?.. It's because the designer of the bullet train is a bird watcher and designed the nose of the train in that way to reduce sound pressure when exiting a tunnel
At 16:38 he says that they increased the “flow” by increasing the overall voltage. Looks like you got amperage and voltage mixed up in your analogy there Hammyboy- Amperage is equivalent to water “Flow” in say a hose whereas Voltage is equivalent to the water “Pressure” in that hose. Finally, in that same water hose analogy, Resistance is equivalent to the diameter of the hose. Just though I’d point this out real quick...
Voltage is the output from the source to the motor, amperage is what you have to push through the wire to get the voltage. The resistance in the wire is Ohms and dictates the output voltage. English isn't my first language but I hope it made sense.
You can't simply increase current. Batteries are voltage sources and current sources are as real as unicorns. You can, however, increase the voltage so that more current may flow through.
@@wedmunds Who's talking about batteries?
@@Salpeteroxid He's replying to the initial comment, not you. Batteries are just an example of a voltage source, but he's right. The easiest way to increase amperage is by increasing voltage, so he was correct
@@mitchellbuehler6058 Sorry, sometimes English gets confusing when there are a lot of information in the same sentence without braking it up.
At least toddlers can watch this and understand it
i love the bloke wearing a suit while charioteering. class
The Japanese Shinkansen 10 billion passengers, zero fatalities makes this the safest form of transport on the globe.
At 30:35 he says ancient charioteers couldn't have possible known about Newtonian laws but somehow they instinctively knew. lol Well yea, we learn these things as soon as we start walking. We don't know the formulas behind it but we know/learn what works.
Even some animals figure out some basic physics. When playing fetch, a smart dog can predict the path of a ball and cut angles to intercept the path of the ball (my German Shepherd does this) My German Shepherd even predicts how the ball will bounce off a wall. She sees the ball going towards a wall & she positions herself to catch the ball after the bounce. She knows where the ball will go after it bounces off the wall.
lol My small mutt isn't a dumb dog but she doesn't do that. She just chases directly after it. She will chase it towards the wall & doesn't alter her course until after the ball bounces off the wall. Anyways, my point being, we kinda figure out how things work. If you are running & want to turn, you gotta lean if you don't want to fall. Nature or nurture, it doesn't matter. All animals figure out the very basics like leaning and it doesn't take human levels of intelligence to figure out more complex things like predicting the path of a falling, or moving ball.
A Cheetah's tail for example.
* German Shepherd
All the credits this video attributes to are just random bullshits.
most pointless comment ever.
Richards second bullet train since the top gear Japan episode?
Great work Sir Richard
I respect the time tables and the fact that on average it’s only maybe a minute late at worst, the drivers are under a HELL of a lot of pressure to maintain timetables
BFC which I’ve heard is basically Hell on Earth
300系が走っているという事は2012年以前のものなので少々古め。
Yes, hello
@@chilton7853 Well, according to Google translate, he spotted that there was a 300-series in one of the clips, which was retired in 2012. They did seem to use a lot of stock footage in this documentary though, but I reckon it's been kicking about a bit anyway. I went to Japan in 2008 and the N700s were doing the Nozomi services back then.
It's a shame they didn't show some more footage of other trains, instead of the same ones of the N700 going over the same bridge in front of Fuji. They're an ugly beast, especially when compared with the 500 or the original 0 series.

30:19 Hamster hasn't got enough mass for that
Richard Hammond talking about trains :-O
This show is now my quarantine time show
great information. Hammond is still shorter than most factory workers and train passengers.
A normal train Runs on 15.000 volts. At least in Sweden, Norway, Switzerland, Germany, Austria and several others having adopted the norm in 1913. Hungarian innovation in the 1920s was to use 25.000 instead.
Even at 15000 Volt AC are much better than classic 1500-3000 V DC systems. Multi-voltage locomotive in Europe are limiting their power under 1500-3000V DC system.
how cute was that.... when he's listening to a japanese lecturer. 😆 46:55
Totally.
I remember watching this when I was too young to understand.
Memories~
I need to watch this more often
42:04 That's the prettiest pile of scrap I've ever seen!
27:05 Bunta Fujiwara would not be happy about that

Thank you so much for this detailed explanation! I have been enjoying travel by shinkasen since 2001. I prever Shinkansen to aircraf!

Trivia: The scene at 45:42 is a different view of the same area found on RUclips's Tokyo Live Camera CH. 1.
Good quality video, and none of the overwhelming back ground music swamping what James is saying in the James May episodes on this channel..
これGT-R vs 公共交通機関のヤツ思い出すな
But you didn't tell how the braking system works at that speed!!
I think it's regenerative braking.
Probably eddy current brakes combined with regenerative braking and some conventional brakes for lower speeds
Now let's see how well the trains handle the bends, with The Stig driving !!
The voltage is literally slightly higher than the standard 22,000v that are used on semi long distance AC power lines but there are urban substation transformers that step down the voltage for homes but commonly major structures like shopping centres will be directly connected to the 22KV lines and have their own step down transformers so they don’t overload the low voltage lines that are used by homes! :)
トップギアに出てたおっちゃんやん！今は出てないけど
nothing about aerodynamics??
Here I go again, watching documentaries at 4am
During the chariot demonstration, found myself leaning with Richard 🤣
This guy likes other stuff than cars? I am surprised!
money ;-)
He's a TV host. He did whatever show he was paid to do. This is quite old tho, later in Top Gear days, ad also nowdays in Grand Tour he gets so much money for a season that he doesn't need to do any side projects.
The fastest train, pause, in the world.

Great great video 👍👍👍🔥🔥🔥
Great to watch.How do the breaks work for such high speeds must have been added.
this channel is uploading very old documentaries.
No shit Sherlock
Was it Hammond's lack of goatee and wrinkles that gave it away? I'm thinking it was released before March 11, 2011, too, since he doesn't mention the Toohoku Earthquake and Tsunami.
he makes it sound like having 3 jumbo jets take off every 5 minutes is somehow not gonna work even though heathrow has a plane take off every 90 seconds
The bigger the plane the longer it takes to take off. I hope that is simple and more obvious enough an explaination for you.
like i said heathrow has a strict schedule of 1 plane leaving every 90 seconds as one is heading down the next one is pulling up onto the tarmac ready to go also a jumbo jet is a 747 which are the primary planes that leave heathrow mostly
explain all you want it wont change the fact that many airports are already sending jumbo jets off at 3 every 4minutes 30 seconds
The main thing, is the follow distance behind A380 and B747 aircraft, with the bigger one creating even more wake turbulence, than a 747. The smaller planes can take off closer to each other, but with an A380, the smaller plane, behind that must wait for a longer time before, doing the takeoff roll. Smaller planes have crashed, when following too close to a 747, or a380, due to the wake turbulence. Also a large 4-engine airliner will use most of the length of a runway, during takeoff, to reduce engine wear. They do have it down to a science with, what planes go next on takeoff. Having mostly small, to mid sized aircraft, will allow for shorter times, between takeoffs. If I was in the small plane, I would want to takeoff, before a 4 engine jumbo airliner. They could have the jumbo takeoff in one direction, and the following smaller plane, take off, in a different flight path, to allow for quicker take offs.
That's a very good observation. I checked the data on heathrow, and various sites claim between 650 and 700 landings each day. Which is quite a lot less then your 960 a day, but i guess you are just counting the most active hours.
But these trains are so much more comfortable to travel in than via an economy seat in an airplane, so i am on the team train. :>
That was really amazing. So many new things to learn and so many ideas for a high speed train.
I got to say, the greatest presenters (of anything) ever are Richard Hammond, James May, and Jeremy Clarkson. They should be knighted. Can you imagine if Richard Hammond explained your 6th grade algebra...I'd have gotten it the first time...not 3 years later! I'd also knight Graham Norton as the greatest late night talk show host EVER! They should be doing educational videos in our schools. They can make anything, any subject, interesting. Education thru entertainment.
True...
derekspace your missing one . David attengburgh
6:33 It derailed on the crossing because the flanges hit the crosswalk, not because the track was straight, the additional wheel radius added speed and caused the trolley to turn right.
12:18 you're so very nearly right, it's not the springs as they only dampen vertical oscillation, what you're looking for, is actually yaw dampers, like the springs, they're also attached to the frame of the train.
The difference being is that they're dampers, similar to those found on self-closing door mechanisms, it's to resist sudden & violent movment of the way bogies turn & shift.
12:43 Again, soo very close but not right there, the rails are grinded down regularly to remove rust & corrosion which would have adverse effects on stopping distances, yes wear does happen but yeah, this is also the case.
