Its not that the US doesn't have the technology it's more to do with they have no use of concrete bases for tracks.

As for the Chinese tracks just wait for another five years or so then argue if it was sub par or not since the communist government is certainly not going to disclose anything that is going to discredit themselves.

As for cost of maintenance being higher for 380Km/h trains/tracks compared to 300km/h trains that is a fact based on physics since 380km trains/tracks are under higher strain due to higher energy transferal compared to 300km train/tracks resulting to more wear & tear.
Well, it is, definitely, cutting edge technology.

Richest man in the world

Meet Liu Zhijun:

Quote:
The Chinese Railways Ministry Chief, Liu Zhijun was in charge of the construction of the railway, spanning almost 8,100 miles across China and reportedly costing $395 billion U.S. dollars.

Liu was fired In February. He's now behind bars and under investigation for (quote) "severe violations of discipline." During his seven years as chief, he embezzled a personal fortune of $120 billion U.S. dollars.
About as rich as Carlos Slim and William Gates combined.

Since over 30 % of the costs of HSR network went to the pockets of Zhijun alone, how much did his accomplices, henchwomen and henchmen share among them, and how much was actually spent on HSR network?

where did you find this piece of crap? NTDTV, or epochtimes?

edit: I didn't realize you quoted from Gadiri's post, just didn't read his post carefully. but hey, NTDTV! Those Falungong nutcases are always funny making up numbers and things.

There are other examples of its use, but it has started life as non-high speed in the UK. Its use will spread, and the new High Speed line is projected to use the technology.

Lol, so he's richer than Bill Gates now!

Isn't it incredible that we haven't had these rumors for years till suddenly China is aiming to export its HSR and train set technology? Sounds like pure unfair competition sustained by the sickest professional liars in this world: journalists.

All tunnels constructed by a tunneling machines are fitted with prefab concrete so most subways built in the last 2~3 decades are all prefab concrete bases for tracks including the ones in the US.

Really get your facts straight.

Grande vitesse : la Chine ralentit



Thyristorchopper

15/04/2011


A partir du mois de juillet, les trains à grande vitesse chinois seront limités à 300 km/h, alors qu’ils atteignent parfois 350 km/h, a déclaré le 14 avril le nouveau ministre des Chemins de fer, Sheng Guangzu, dans une interview au Quotidien du peuple.

A partir du mois de juillet, les trains à grande vitesse chinois seront limités à 300 km/h, alors qu’ils atteignent parfois 350 km/h, a déclaré le 14 avril le nouveau ministre des Chemins de fer, Sheng Guangzu, dans une interview au Quotidien du peuple. « Il y aura des trains directs, d’autres marqueront des arrêts dans chaque région, et il y aura le choix entre deux prix pour satisfaire les besoins de tous les usagers », a proclamé le ministre. Les travailleurs migrants ont du mal à s’offrir des TGV de plus en plus chers et sont obligés de se rabattre sur des trains lents de plus en plus rares. Cette mesure doit permettre aussi de renforcer la sécurité des trains. La Chine possède le premier réseau de lignes à grande et très grande vitesse au monde, long de 8 358 km. Le réseau doit être étendu à 13 000 km en 2012 et à 16 000 km en 2020. La ligne Pékin - Shanghaï, 1 300 km, qui doit ouvrir en juin, devait être circulée à 350 km/h, comme sur celle déjà ouverte entre Wuhan et Canton. Au total, la Chine va investir entre 2011 et 2015 quelque 2 800 milliards de yuans (296 milliards d’euros) pour construire environ 30 000 km de lignes de chemin de fer, selon le ministre
http://www.ville-rail-transports.com/node/15773

Sum-up :
China is going to reduce HST speed from 350 km/h to 300 km/h next july.

This is for security and because migrants workers are seeking for trains cheaper and less speed. Prices are to expensive.

What do you think? with sound bites like 120 billion US$ private fortune? Embezzled in 7 years... yes sure!

Common sense, dude, common sense...

Falungong 'media' (NTDTV, epochtimes, all this sort of bullshit) is the worst kinda source you should refer to. actually I find it amusing that they claim Liu Zhijun embezzled 120 billion us dollars, even more amusing than that they claim their 60-year-old master installs a wheel in everyone's abdomen, and if you don't follow their master's will, your wheel is gonna explode and kill you(I wonder if their master ever installed a wheel in Jesus's abdomen). Another interesting thing, they claim that more than 90 million CCP members have quit the evil communist party because of their efforts. (FYI, there are in total less than 80 million CCP members including Hu Jintao. lol)

I think this is just the tip of the iceberg. At this rate, they may have to shut the thing down. How can you open new rail lines if the whole thing is going to fall apart?

You think all prefab concrete is the same? Are you talking about ballast-less track technology used in 350km/h tracks or something else??? I am talking about ballast-less track for high speed, it is definitely cutting edge and very very few companies can built such a thing and none of them are in USA. Sure, if USA wants, she can do it, also I believe with enough money they can send humans to Mars, too. (Not joking) However, right now, there is no company which can built this sort of track in USA. They need R&D and testing before they can produce smt like this.

Again get your facts straight mate.
There is no secret formula in creating pre-stressed prefab concrete slabs. The US was the forerunners of prefab concrete manufacturing.

LOL, what kind of unsubstantiated bullshit is this? There's no real evidence that China used anything but the highest quality materials in its HSLs.

Didn't you see the articles that specifically mentioned poor construction and materials?

Of course, because all engineering is the same when you use concrete

You are one if the last people on this forum who should be patronising someone else about getting their facts straight.

Not sure whether you are genuinely naive or just trolling. All those articles have been quoting some mysterious "source" that claims everything will fall apart soon. The fact that the HSR has been running in China since 2007 without any incident related to "shoddy construction" speaks for itself. Most of the articles were written by people or organizations with their own agenda, fundamentally fueled by jealousy towards China's success in HSR development or the Chinese economic success in general.

The move to reduce speed on the line only serves two purposes, one is to destroy Liu's reputation, which I don't give a shit; second is to reduce energy consumption and maintenance cost so ticket price can be reduced, which I welcome wholeheartedly.
