The following link shows that the world fastest train travelling at a speed of 515.3 kmph is travelling at almost half the speed of light.

I think it should almost half the speed of sound.

So those guys where there is some proof reading and editing is involved can make typing mistakes.

Hey i'm not from france, lol, but yeah... 515.3 km/h

And the amazing thing is that the TGV was built in 1989 !! (The 1981 did a top 380km/h)

These are the TOP speeds though, and are not reached on their typical runs.
Operating speed is around 300km/h.

ps - though i think the point of this thread was a "journalists mess up again" comment...(speed of SOUND is ~1188km/h)

Man, what a misleading title... the article doesn't mention speed of light.

I clicked on this thread thinking of theory of relativity, how it affects the passengers, figured it was a fantasy fiction about the future.:ZZZ:

There is a train that goes from Shanghai airport to the city. Its a Maglev and supposed to be the fastest. Not sure about the numbers.

Second paragraph, second last line.

Speed of light roughly is 3,00,000kms/sec if I'm not mistaken.
Half the speed of light comes to 1,50,000kms/sec.
Roughly,distance between US and India is around 16,000kms,so,would that train take maybe a 10th of a second to travel between the two countries??!? hehe..

cheers,

I wonder if timesofindia people know the difference in speed of sound and speed of light

ekjhactly.....agree:

On that same note if you go a little ahead and read about AVE trains (http://people.indiatimes.com/quickie...id-1419194.cms) they say the empty train weighs 392.620kgs and a loaded one about 421.500kgs!!!

Beat that. I mean my unladen Indica weighs more than double that weight. :D TOI should seriously start firing a few people in their proof-reading dept. You should see the amount of grammatical mistakes, misspelt words and half-eaten paragraphs that show up in TOI nowadays with alarming regularity. Someone there is definitely napping :P

In certain european countries, they use fullstop instead of comma. For example, one thousand would be 1.000 instead of 1,000 or one million would be 1.000.000. I think TOI didn't convert the number to local scheme before printing it.

TGV is indeed capable of running at that speed. However, during the test run of 515 km/h, it was pointed out that to stop the train from at that speed, the brakes need to be applied 32 km before destination. It was highly impractical. And for some other safety reasons, the actual speed was reduced to around 250-300 km/h. But still they need to apply brakes 8 km before station!

Rehaan is correct about the info on TGV and their operating speed. However, their glory days were in the nineties. Now its the turn of those sky-train (bullet-train) kind of things that levitate with the aid of magnets etc. (Sorry, cant recall anything more specific about those right now).Those have recorded a faster speed than TGVs.

And Samurai is right about the numbering scheme. The french use fullstops instead of commas.

that is using super-conductor magnets, if i am correct.

32 km!!
Imagine a cow or guy ambling on the tracks like here.:-D
