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.
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.
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.

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
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
"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.
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.
Brilliant documentary. Only thing missing is Clarksson commenting on Hammonds failures. :D
HAMMONDDDD!!!
Hammond you blithering idiot!
"Hammond you idiot..."
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
Just got back from Japan and my God what a marvel of a country. The Shinkansen is an engineering miracle
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.
Anyone else in love with that second bike and sidecar combo? The leaning mechanism is very cool.
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.
@@adam.dzwoniarek72yes, 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...
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)
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.
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.
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
my brain grew 2 sizes after watching this.
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.
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!
I enjoy education system that is informative, encouraging and entertaining. Thanks for great effort to share knowledge in such fun and inspiring way.
“The stopping is going to be uncomfortable” he says as the prototype destroys as it rams into the end 😂
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
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. 😍😍🤯
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.
A Class-A Documentary! Great work!
what a beautiful train, the science is awesome, thanks.
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.
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
Amazing documentary by Hammond
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 >:(
Great video and No ads makes it great.
DALE BECK lucky you, I’m infected with ads
None for me either.
Used to love watching this series after school :)
this is frickin amazing!!
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...
At least toddlers can watch this and understand it
Thanks for uploading
I need to watch this more often
21:34
Dodge: That's where you're wrong kiddo
22:00 i can hear Clarkson shouting "Nonsense ! POWEEEER !
Very informative and educational indeed !
I like this guy because he explains each and every thing.
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.
Just to be clear, springs by themselves do not dampen, the coil-damper unit dampens motion.
Great documentary!
Wow what a great documentary thanks man
just sitting here, waiting for the stig to pop up, to take it for a spin on the track...
anyone else???
also here, because i kinda like that dude called hammond...
I have to say.. that second side car is so cool
Didn't realise it had only one wheel... mind blown!
Amazing! Thankyou!!
Great work Sir Richard
Richards second bullet train since the top gear Japan episode?
36:25 that's very true. 19th September 2017, a Mexico City Subway train derailed during the deadliest earthquake in my country since 1985
Amazing work done on this video
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
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 .
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...
It has been two hours since I’ve seen this series I need to watch it again
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
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.
なぜ彼らは私たちに古いテクノロジーを見せているのですか

このビデオを作った時は最新だったのでしょう｡
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.
This show is now my quarantine time show
i love the bloke wearing a suit while charioteering. class
Most advanced country in Asia is Japan..keep it up Japan..
Trivia: The scene at 45:42 is a different view of the same area found on TH-cam's Tokyo Live Camera CH. 1.
Richard Hammond talking about trains :-O
The Japanese Shinkansen 10 billion passengers, zero fatalities makes this the safest form of transport on the globe.
great information. Hammond is still shorter than most factory workers and train passengers.
30:19 Hamster hasn't got enough mass for that
42:04 That's the prettiest pile of scrap I've ever seen!
Good Documentary. 💯💯💯
I remember watching this when I was too young to understand.
Memories~
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.
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.
Awesome been in it many times love it.
The best ka tlga brother
27:05 Bunta Fujiwara would not be happy about that
😂😂
how cute was that.... when he's listening to a japanese lecturer. 😆 46:55
Totally.
Yes! I found it in high quality.
Thank you so much for this detailed explanation! I have been enjoying travel by shinkasen since 2001. I prever Shinkansen to aircraf!
With Japanese technology, Max will be champion next season.

これGT-R vs 公共交通機関のヤツ思い出すな
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.
Great great video 👍👍👍🔥🔥🔥
トップギアに出てたおっちゃんやん！今は出てないけど
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.
Good education stuff.
That was really amazing. So many new things to learn and so many ideas for a high speed train.
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.
The fastest train, pause, in the world.
w r o n g
Great to watch.How do the breaks work for such high speeds must have been added.
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
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
