1000 mph train!

IS it possible? Without considering maglev or future tech is it possible to get a train to hit 1000 mph without sploding?
Comments
Yes, it's possible. A solid fuel rocket on rails. Hell, you could do it with a jet engine, probably. Of course, if you're doing this in air, you'll be dealing with a supersonic shockwave.
If this ever happens, and it may, it will be done in vacuum (or near vacuum, as some resistance may be desirable for safety reasons) tubes, possibly with a maglev system for minimum friction. Whether it's really efficient or reasonably safe (slowing down'd be a bitch) is another matter.
[B]Well, he didn't say it had to be built around the current train system. [/B][/QUOTE]
Actually, he pretty much did. :)

[B]It does unfortunately figured friction would kill it. Even with a strait track theres no hope of going near a thousand? [/B][/QUOTE]
Even with a straight track the friction is still important for accelerating and deccelerating.
It'll get you where you're going.
[B]OK, if we're talking non-standard train tech, then yes you could do it provided you didn't have to turn (feasible in many situations) and you used rockets or jets or something like that for propulsion and breaking (plus air brakes, naturally), and had a track that you didn't just sit on but were held to somehow. If you were actually held to the track you could even manage turns over a large radius. [/B][/QUOTE]
In the latter, track could even be raised off the ground and banked to extreme degrees, possibly as extensive as 75-90, and the train could feasably still move along it. at incredible speeds, even turn and keep the passengers comfortable, as centrepital forces would be more than enough to keep them (and the train) planted.
we could beat the airlines !
INVEST IN ME AND WE SHALL RISE TO THE SUPER TRAIN !
P.S.
Whats the cost of building & the daily maintaince gonna be like? What exactly is "rocket fuel".
[B]Would the rockets be able to function for three hours? [/B][/QUOTE]
You'd be better off with jets. More efficient, and it's pretty clear that they can function for 3 hours happily. :)
[B]We could do it with [i]Rearden Metal[/i]. [/B][/QUOTE] Atlas Shrugged?
As for airships, I don't see why not, but what's the practicality? Airships as they stand now are not friendly with higher speeds. They're just giant balloons with passenger thingies strapped on.

I think the idea of a tube would be better, have the shuttle be levitated in the tube using electro magnents, then used compressed air to " fire" the train down the tube. This would also help cut down on evironmental factors that could effect an ulta-highspeed train that's exposed to the elements (Think bird at 600 mph...)

Would it be practical? Not at all. Not to mention that pesky sonic boom you have to deal with. Can't have that running in any proximity to anything.
