China is planning to build a 1,000 kph locomotive, which would nearly double the current record speed.  (Source: China Daily)

Design would almost double today's record speed

We've discussed a couple of times the U.S.'s growing gap in high speed rail compared to China.  As fossil fuels become more scarce, more expensive, and more dangerous from a political standpoint, mass transit solutions look increasingly appealing.  High speed rail is particularly promising as it promises not only to reduce fossil fuel use, but also to get you to your destination faster.

Researchers at the Chinese Academy of Sciences and Chinese Academy of Engineering (CAE) reportedly are preparing a record-shattering 1,000 kilometer per hour train, according to the 
Beijing Times.  

The new trains will make use of a vacuum tube to reduce friction losses.  They will first build a prototype vacuum magnetic suspension train capable of traveling between 500 and 600 kph.  That gives it a shot at breaking the record set by Japan's JR-Maglev train, which achieved a speed of 581 km/h (361 mph).  The record for a traditional railed train was set by France's TGV at 574.8 km/h (357.18 mph).

After the prototype, the group plans to implement a smaller train capable of speeds of as much as 1,000 kph.  Shen Zhiyun, a member of the research team, comments, "The speed can be reached by making vacuum pipelines for maglev trains to run through, with no air resistance."

Daryl Oster, who owns the U.S. patent on evacuated tube (vacuum) rail, now works at the CAE.  Along with Zhiyun and another researcher, Zhang Yaoping, he is leading efforts to deploy the technology.  The team hopes to begin laying ETT rail lines within the next ten years.

It would use less steel than current trains, but would be slightly more expensive.  China is targeting a cost of 200 million yuan ($29.54M USD) per kilometer for its traditional rail.  The Evacuated Tube Transport (ETT) rail would cost approximately 210 to 220 million yuan ($31.0M USD to $32.49M USD) per kilometer.

Currently the planned trains travel at 350 kph.  A cost increase of 5 to 10 percent seems a fair tradeoff to score nearly twice the speed.  It's just one more example of how ambitious China is when it comes to high speed rail.

Why in the hell would you want to go that fast in a train? We have seen what happens to vehicles let alone passengers themselves when they go that fast, and guess what, it only takes a split second to achieve those results. Be it on a rail or not, it doesn't need to exist, let alone in China, where I can imagine only a handful will even be to afford this. That's what we have Amtrak and jet planes for people!

Actually, there is no inherent danger in going 1000 km/hr. The acceleration up to that point can be dangerous if it isn't gradual. Rapid deceleration, especially when the deceleration is caused by hitting a stationary object with your face, is generally considered hazardous, but once you’ve accelerated, you won’t even know you’re moving unless you slow down, speed up, or change direction.

Deceleration is not a word, the correct word to use when slowing down is acceleration.

The cruising speed of your jet plane (somewhere around 900km/h, max speed around 1100km/h) is just a little lower than this 1000km/h train. I would debate the safety of flying in a tin can in the air (with only aerodynamics and jet thrust to hold it up) with that of being connected to the ground by rails(a more simple machine). Both go the same speed and operate in similar 'vacuum' environments. I think I would just prefer to be on the rails.
