""The Fuxing class trains are designed to travel at 350 kilometers per hour on average with a maximum speed of 400 km/h," designers at the China Academy of Railway Sciences, or CARS, revealed in a statement."

Does this mean that the current 300 km/h top speed limit will be relaxed for the new CRH400 trains?

I very much doubt revenue service will exceed 300 km/h anytime soon. First, the previous generation designed for 380 km/h and never saw anything above 300 km/h in service. Second, there is no commercial service in the world that significantly exceeds 300 km/h, and that includes many services that are in a stronger financial position on the operations side (Chinese HSR tickets are by far the cheapest in the world and receive significant subsidies).

300 km/h is probably the fastest the current generation of HSR technology will get us in revenue service, and it's remained at that level for decades now. It'll probably take maglevs to make any economic sense to go faster.

Your words are speculative vis-a-vis theirs, which was an official announcement. If you had read into theirs, they made claims of improvement in technology that make 350kmh realistic rather than hype.

First, it is already 310km/h. I know it may be just 10km/h but still 300km/h is not the maximum. Second, and more significant, Chinese high speed trains run at 350km/h literally for years until the infamous Wenzhou train accident after which speeds were lowered not because of economics but more due to politics/management.

I bet with the new trains, after a certain operational period, we will see 350km/h. I give it ~one years.

Maglevs make no economic sense. CRH has demonstrated that +300 running on conventional tech is viable if you want it.

Economics did play a role in the slowdown. Running significantly over 300km/h really increases operating costs but the Chinese were willing to swallow it for bragging rights. After Wenzhou, bragging doesn't really cut it when your image was that tarnished. Plus the government needed to show the people that they have done something in response to the accident. I could see them raise it back to 350-380km/h given that confidence in the CRH system is quite high now. Today, the Beijing-Shanghai HSR operates at a huge profit. They could push speeds higher for more capacity and attractive travel times. Other lines also operate at a profit but given that they are shorter intercity lines running those at a higher speed really does not make a big difference to a regular traveler.

hi guys,today Beijing-Shanghai HSR have tested 350KM/h commercial run,with CR400A/BF ,here are the pictures.350km/h is not far from us.
the train number is G9/G10,no passengers on the train,the fastest time is 4h12min.with 2 stops at City Xuzhou and Nanjing.

It has already been seen that the reduction of speed was previous to the accident.
But really the current top speed is 309 km / h?
Shanghai – Kunming high speed line completed. Railway Gazette 28 Dec 2016.
Quote:
The line has been designed for 350 km/h operation, with trains initially running at up to 330 km/h according to China Railway Corp.
On the other hand, what does it mean that the CR400AF has a top speed of 400 and an average of 350?
In order to homologate to 400 it is necessary to circulate of sustained form to 440 with slope of 5 mm, the average speed depends on the stops and the design of the line.

The train attendants look pissed that they might have do this for many passengers at each station from now on.

Speed depends not only on the train but on the curves of the line. Certain segments of newly-built lines allow cruising at 400, for instance the almost-started-construction Russian HSL2 eastbound from Moscow to Kazan and later to Yekaterinburg. Existing Chinese lines allow at some segments cruising at 380, but to my knowledge no regular commercial services do it. In part because even though the line allowed, the trains that could sustain it didn't exist before. Which, in turn, shows that infrastructure engineers were wise enough to look a little bit into the future.

As for the economic sense of maglev - well, at any given level of technology development it allows 50% greater cruising speed. For instance, when the shanghai line was built which can stand 450 km/h [although yes, for a brief dozen seconds after which it's time to slow back down] the typical crusing speed of conventional HSL was 300 and there were some talks about 320.
Now, as far as i understand, the almost-completed Japanese maglev is designed for circa 525-540 km/h cruising speed while conventional lines do 350-360. The profitability, including the relative one against conventional HSL, remains to be seen.

CHINA | High Speed Rail

From the rumor mill, 350km/h will happen by the end of the year at the latest and autumn schedule refresh at the earliest. I wonder if the speed up will be a blanket roll out that applied to all G trains or will be slowly rolled out on a line by line basis. Also If D train will go back to running at 250km/h as well.

Rail Corp supposably will roll out airline like differential pricing and yield management as well, I guess they will have give out some benefit rather than just blankly increase price.

Looks like HSR in China is finally growing back it confidence and profitability.

Can we have one with just a stop at Nanjing? Pretty please?

High-speed train to reach Shanghai from Beijing in 4 hours

http://www.ecns.cn/2017/07-19/265957.shtml

Trains on the Beijing-Shanghai high-speed railway will be traveling at up to 350 kilometers per hour around this year's National Day, Beijing-based Caixin online reported.

The speeds of "Hexie" and "Fuxing" class bullet trains will both improve, and the time required for the G1 train to run between Beijing and Shanghai will be shortened by 49 minutes to 4 hours.

China Railway is currently preparing for the speed increases with multiple departments.

A China Railway Signal & Communication Corp member noted that staffers are testing tracks, train vehicles and signals.

China's high-speed rail system began to slow down from July 1, 2011. All the high-speed trains that could reach a top speed of 350 km/h were slowed to 300 km/h except for the ones running between Beijing and Tianjin.

He Huawu, chief engineer of the China Railway Signal & Communication Corp, noted that the decision to limit the top speed to 300 km/h was mainly based on operating and maintenance costs, which increase with higher speeds.

But there are always voices calling for more speed.

After the limit of the Beijing-Shanghai high-speed railway is boosted to 350 km/h, the Xuzhou to Xi'an section of the Lianyungang-Lanzhou passenger line, the Beijing to Wuhan section of the Beijing-Guangzhou high-speed railway, and the Shanghai-Hangzhou section of the Shanghai-Kunming passenger line will also increase train speed to that level.

The Beijing-Shanghai high-speed railway is 1,318-kilometre long and connects two major economic zones in China, the Bohai Economic Rim and the Yangtze River Delta. Construction began on April 18, 2008, and the line opened to the public for commercial service on June 30, 2011. The rail line is the world's longest high-speed line ever constructed in a single phase.

Could this FINALLY be the time when we'll be seeing trains running 350km/h again?

Can we expect most current 200km/h lines to be increased to their design speed of 250km/h too? Like the Coastal HSR from Shenzhen towards Ningbo?

Are the coastal lines maxed out at 200km/h currently?

Trains go 200km/h (up to 210km/h or so in reality) on the coastal line.
