French Train Breaks Speed Record 612
Josh Fink writes "A French train on the TGV line has broken the wheeled train speed record - again. At a speed of 350 miles per hour, they came close to breaking the all time record of 361 miles per hour, held by a Japanese maglev train. It was last broken back in 1990. From the article: 'The TGV, short for "train a grande vitesse," as France's bullet trains are called, is made up of three double-decker cars between two engines. It has been equipped with larger wheels than the usual TGV to cover more ground with each rotation and a stronger, 25,000-horsepower engine, said Alain Cuccaroni, in charge of the technical aspects of testing.'"

More rail development is needed (Score:5, Insightful)
The major problem is being crammed in with a lot of other people, some of whom may not be at all polite or tolerable. Security on such trains needs to be well maintained, and probably different cars with a people density/cost tradeoff. The Dallas light rail system (DART) which opened up a few years ago started on a good note - the major problem was too many people wanting to ride it from too far out. In theory, this might be handled with running more lines in parallel as the rail system gets closer to the center of the city - it's an interesting problem. (Of course, the expense of putting a rail system through a city not designed to accomidate it is non-trivial...)
Regardless, I think the more efficient resource utilization of trains makes them a no-brainer for long term development. The US is lamentably far behind - Amtrack is stuck playing second fiddle to freight trains and has abysmal performance (I'm probably biased as I was once 17 hours late on a train...). Freight rail and passenger rail need different tracks and independent scheduling - freight can move more slowly over rougher tracks, but passenger rail needs to be rapid.
I have always wondered if a properly designed and implemented rail system across the US would be cheaper than air travel (and not all THAT much slower, for bullet trains, particularly given delays airports can introduce...) I guess it's the old bootstrap problem - no money to lay down tracks because there is no guarantee of return on investment, while air travel already has massive inertia behind it and a lot of financial clout to use on the political system.
I hope someday we can muster the political will to build a rail infrastructure the way we have built a highway infrastructure, because there may well come a time when raw materials are too expensive to make building massive car fleets and replacing them every few years economically viable. It would be nice to have a fast, inexpensive way to travel that is actually able to provide reliability.

A gasoline engine is only about 25% efficient, so the dragster has to dump at least 24,000 hp as heat from a much smaller volume. However, top fuel dragsters are probably much more inefficient than 25%; IIRC, they burn several gallons of nitromethane in a 5-second 1/4 mile. By my calculations, if they burn 4 gallons in 5 seconds, that's a rate of 52,000 hp of chemical energy, most of which must be dissipated as waste heat.

The problem with passenger rail transport is it's very difficult to run it at a profit - especially if the infrastructure isn't there to begin with. Getting people out of cars and onto trains is much harder than the other way around. So it's not particularly attractive to private companies.

I think the other issue is that competing modes of transportation get a lot of their infrastructure handed to them, basically for free or with big subsidies, by the Federal government.
If you're a bus company, you don't have to pay to use the roads, the government has already done all the hard work for you. You just drive on them. Same with over-the-road cargo trucking. This is a huge problem for freight railroads, who would otherwise beat the tar out of road trucking: except for UPS and other time-sensitive parcel-deliveries, there's really no reason to haul bulk goods by truck, when you can take the same containers even, and put them on a train and drag them around for a fraction of the fuel cost. But the freight railroads also have to pay, not only for their locomotives and rolling stock, but also for the right-of-ways, maintenance on the track, keeping them clear during the winter, etc. All the trucking industry pays for is whatever the government adds on as a tax to diesel fuel, plus their direct taxes. (And the fuel taxes don't even start to cover the budget for the Interstate system, which is hugely damaged each year by high-axle-weight vehicles like trucks.)
With aircraft, although they admittedly don't require a huge amount of infrastructure when they're in the air (and good thing, too), things like the navigational beacon systems that IFR relies on, plus the Air Traffic Control system/network, are government-run. Sure, some of it's funded with taxes, but I'll bet you it's not 100% self-funding.
I think we can go either way -- either have the government pick up the tab for maintaining the nation's rail network, and make it available to anyone who wants to use it, in the same way that the Interstate highway system and the Air Traffic Control network is, or make users of the ATC network and the Interstate highways pay for their entire budgets so that they're self-funding without any support (and have them pay back over time the cost already contributed) -- but we're only hurting ourselves with the current arrangement. Anything that encourages an inefficiency to continue is inherently bad, and we suffer as a result of it due to higher gas prices, and geopolitical conflicts that arise due to petroleum supplies.

That is actually a major problem across western Europe right now. Train companies are slowly abandoning medium and short range stretches in favor of the more lucrative business traveler market, and investment in the medium and short range track and trains is languishing, resulting in deteriorating quality and frequency of service. As such, people are forced from the trains to private cars, which bring all the problems of pollution and urban sprawl that we Americans know so well. Furthermore, at these speeds trains do not run much more energy efficiently than planes either.
That is what happens when you privatize things that should be public services.

The whole argument of population density here in the States is a load of sheep. The United States has roughly the same land area as China, and likewise, has a majority of high population density tilted on the East coast.
When I was in Shanghai, a maglev train from Pudong airport to our ex-pat section was roughly 15 miles and cost around $5, traveling about 450 Km/H (250 mph). With 20 million+ people in Shanghai, there's no reason this cannot be done similarly in New York, LA, or Chicago. Imagine a $60 trip (or less) from Boston to New York. Better yet, at $5/mile, a straight shot from Dallas to Houston is around 250 miles (about 50 miles more distance). I was around when they were still expanding the I-45 corridor from Dallas to Houston (it helped provide an economic boom between the two). In 2005 alone, our Texas highway systems accounted for over 100 billion into our overall economy (feeder roads, tractor-trailer delivery, exports, new construction, efficiency, etc). Think about long hauling regular cargo over this rail instead. Also, all you Texans out there imagine a 250 mph rail from Dallas to Houston for a commute. It's normally a 4 to 5 hour trip. Now, with maybe 3 to 5 total stops, it would only be an hour and a half or so (which somedays, believe it or not, takes almost that much time for just a traffic commute of 20 miles from one end of Dallas to the other). In a capitalist country, we could easily drop that $5/mile cost even further.
The article mentions China is interested because they will replace the 10 hour train ride from Shanghai to Beijing. I've taken that trip as well. It was a non stop overnighter on a "old" style bunk cab that cut through several small rural cities (much like we have here between major cities in the States). I thoroughly enjoyed that ride, since it was quite nostalgic and peaceful (except for the smoke filled cabs, squeezing past people sleeping in chairs in the aisles, and a hole in the floor for a shitter). The Pudong maglev was pure luxury, and at 250 mph was so smooth I could drink a cup of tea without spilling a drop. You do get something like a sonic boom vibration when the other maglev passes the opposite direction as yours.
Either way, for all you Americans who buy into this notion that it's not reasonable or economical to implement high speed rails here (or use some population density as an excuse), well, quite simply, from the mouth of a native proud Texan, that dog just don't hunt. There is ripe economic potential to be had from these high speed rail interconnects, much like the I-45 corridor provided here over the last 30 or so years. The rest of the world makes us look second rate. And that's quite hard for this 'ole boy to swallow. I think in part we subsidize the airlines way too much here. In over 30 years, we've already floated the note for several and some still can't get their crap together. We need desperately to make a gradual transition away from our reliance on airlines. High speed rail is the answer, and is already proven worldwide to be quite economical and beneficial in so many ways.

Something like the shinkansen is far more pleasant and convenient to ride than a typical plane (especially these days).

If you get south of that line, you pretty quickly run into a lot of nothingness too.

But outside of the (rough) triangle, population density drops off dramatically. (And even so, there are good chunks of that dense triangle that aren't particularly crowded.)
*California* is probably too large for a HS rail network - large parts of it a pretty close to empty. The bulk of the population is in three centers, fairly well clustered together.

I think we should get off our asses as a country and reengineer the IDEA of rail transport. First of all, it has a lot of tradeoffs that make it suck, such as having to stop at "stations" rather than going straight there. It's a group transport, so this makes sense. But what if each "car" had an engine in it, but it gets turned off when it's connected in a "train". Then, the whole sucker could break off from the train after a cross country high speed run and run it's small cargo to a smaller local station. More light rails, with an efficient switching system. Multiple sizes of standard containers so a large single car could offload at the local station to a light rail or truck easily (and automatically).
Use *gasp* computers to model the entire land area and figure out the best places to really put tracks; not the easiest, such as when it was done in the 1800's.
With about a trillion bucks and a few decades, we could have the best system around, perfectly matched automobile and rail standards, easily transfer between the two.
