Yesterday, a french train experimented travelling at 580 kmph on the ground ! I would have applauded it as a great scientific acheivement, if it was for a freight train, but to carry human beings at such an high speed ?
Human beings are not goods that can be carried around at such high speeds. They have a complex circuitry which is a great wonder.
Has anyone analyzed the effect of human body being transported at such a high speed ? What about the effect on brain, heart, nerves and other complex parts ?
Regular flying by airplane itself takes a toll on the body. Ground travel at such high speeds is even more dangerous. Can someone do a bit of research and find out if ground travel at such speeds is safe ?

That should not cause any problem, provided acceleration and braking cycles are moderate. All such high speed trains have closed windows by default. So you do not come in touch with outside air while traveling. Once the acceleration cycle is over and the train reaches a steady speed your body will also travel at the same speed. Due to inertia your body will continue to travel at the same speed, with little marginal force required to counterbalance the friction, wind drag etc.
Acceleration and braking cycles can be easily controlled by the driver. The source of worry is turning. It has been found experimentally that tight turning at high speed leads to a feeling of weightlessness, which in turn leads to nausea in sensitive passengers. The feeling is almost similar to what you feel when the aircraft you are traveling in hits an air pocket and the aircraft suddenly gains or loses altitude.
To avoid that all high speed tracks need to be built with longer turning radius. Moreover there are some other technologies to avoid the discomfiture during turns. One such is micro-processor controlled and hydraulically actuated tilting of carriages during turning cycles.

Even if the train travel 575 kmph,the human beings are almost stable with respect to train.If it is along road it may cause some effect.Here i think no need to bother

This shows how dumb you are !!!
#1 One Ground - Land Speed record racers who cross 1000 Kmph
#2 In Air - Concorde which used to travel at Mach 2 plus!! (civil project, leave about X planes with Mach 6 or more!)
#3 In Space - Space Shuttle guys who travel at 18,000 Kmph!!!
What you say now about humans traveling at such extra-ordinary speeds? 580 Kmph is peanuts for human potential!!!
