JR East Unveils 360 km/h Bullet Train

JR East unveils 360-kph bullet train, world's fastest
23 June 2005
Kyodo News





East Japan Railway Company's next-generation bullet train, which is hoped to achieve the world's fastest speed of 360km per hour (224 mph) in commercial service on wheels, is unveiled in Rifu town, northern Japan, June 24, 2005. The company aims to put the new train into service in 2011, local media reports.

East Japan Railway Co. on Friday unveiled a new shinkansen bullet train in the town of Rifu, Miyagi Prefecture that will operate at a speed of 360 kilometers per hour, possibly the world's fastest.

The two ends of the jade-colored, eight-car test train named Fastech look different. The first car has a rounded end, while the eighth car has a narrow, sharper end.

The train is equipped with a braking mechanism that adjusts air resistance in the event of an earthquake or other emergencies using a half-moon device descending from the roof of the train.

Each car has only one pantograph to reduce noise, down from the two on bullet trains now in operation.

The test runs between the Miyagi capital of Sendai and Kitakami, Iwate Prefecture, will be conducted at a maximum speed of 405 kph.

JR East aims to put the new train into service in 2011, when the Tohoku Shinkansen Line will begin service between Hachinohe and Shin-Aomori stations in Aomori Prefecture.

JR East said it also plans to conduct environmental assessment and other studies to develop cars suitable for operating at 360 kph on a commercial basis.

What are those orange things?

makes the train look like Mickey Mouse. . .
Yup, those are called 'cats' ears' among the railway freaks. They are actually air resistance boards. When Shinakansen slacks up its speed to stop, those boards open from the roof automatically.

This JR East Fastech train looks amazing especially with the pop up 'mini-sail' to assist in slowing down. I guess by 2015 JR will have trains running at near 400 kph or probably by the time the Shin-Amori to Hokkaido Island section gets the go ahead and is perhaps finished by 2020???

I think the "cat ears" it won't be enough to stop the train fast, the train is heavy and goes very fast. How can those stop the train with over 1.7 million pounds of force.
It's a prototype train, I believe...

I never knew such things existed. But I think it looks cute. :)

I assume those "cat ears" are raised slowly when the train needs to slow down. Popping those things up quickly while the train is at high speeds would probably cause a sudden and hard jerk.

just a guess?

sequoias - im sure it would be quite a long process, and not designed to be a 30 second thing.

Obviously the "cat ears" are not meant to stop the train by themselves but to help in reducing speed.

exactly.
There're 12 cat ears on a train, and those sectoral boards open rotarily to shorten braking distance.

Are you sure about that ? I was expecting to reach this speed at a period beyond 5 months, raising the speed steadily.

the cat ears make the train look kinda dumpy, as does its rear end. i like the duck face of the shinkansen 700 though

That's a bit like saying that escape chutes make an airliner look saggy, or that fully-deployed airbags make the inside of a car look a bit cramped! The only time you're going to see the cat ears is in an emergency (or, as in the picture, in testing)...
