It was the same with the 1989 one, which lead to the "duplex" nose.
At 500km/h, "thousands of km" is just 10+ hours of testing.

I did. He was saying because this train was traveling at speeds normally gained by short haul planes and my question was could rails/overhead lines handle running at that speed all the time.

So. THINK Before you post. Then you will know how inappropriate your question is. hypeJR.

Read again, and think about the extra time you need for getting to/ready at airports.

Geez, the US really should invest more in education, lest these dumb Americans continue to wreak literacy havoc on international forums....

The configuration of rolling stock for French's 574.8km/h test run was: Locomotive + 3 motorized cars + locomotive.

It is more like the combination of the locomotives instead of a normal train. 3 cars are motorized, and the bodies of the cars were narrow ones.

So the 574.8 km/h should really be the highest speed of the locomotives, not the highest speed of a normal train, whether it is a commercial one or not.

French should conduct another test run with its most advanced train “AGV”. If it could reach 574.8 km/h, it would be undisputed king of the speed, even it is still a narrow body train, at least it is a normal one.

Your question makes no sense given the context. And if you can't see that for yourself, no one can help you either.

The French train was narrower, but two floors, so this didn't help. Still, I'd like to see them try with the AGV too.

It may have been 10 hours, but my point was that it was not a one-off publicity run.

If rail/overhead lines can handle trains running at 500kph all the time? Read next time, HypeJr.

look, let us suppose it was, by some unimaginable luck if you will, merely a publicity run. Do you think they would have made no preparations whatsoever? 10 hours test run for such a publicity stunt would be merely the prudent thing to do, don't you think?

So "thousands of kilometers" of test doesn't prove it was not merely a publicity stunt.

Although I agree, the data they have gathered in these tests are valuable in themselves.

You are truly hopeless. Use the gray matter you have (and the hints already provided in bold, large fonts). Please.

That's interesting. Can you link the videos in which you saw them?

Awesome train !, i love it too, you got to hand it to the chinese for pulling up this project, not sure when they will have trains traveling faster than 200 km/h in India.

They're actually the videos that were linked here. I only noticed it when the train is leaving the station, so when you see the train start leaving the station look at the wheels.

I guess overhead lines you meant here is pantograph contact with overhead line, i am curious as well how pantograph is designed given huge friction generated at high speed, and this friction is not rolling friction like wheel. I did a little bit research, only found that pantograph contact carbon strip in existing market can only sustain for 300+ kmh.
