Yup.

If steel doesn't cool correctly, you end up with internal stresses from the "lumpy" areas.

For example: the surface of the rail has solidified. However, steel shrinks when it gets cold, but there isn't enough molten steel left to fill the space that is left...

These end up being weak points on the rail.

Those are nice pictures. Thanks for posting. The captions were refreshingly positive.

I can't wait to ride on one of these myself!

High-speed rail network in China is incredible. Good for China, they're doing a good job as I've said in other thread.

However... is China investing in improving non-high speed railways? It has been one of the main errors in Europe in the last decades, we've invested a lot on High-speed railways but secondary railways are poorly mantained, or abandoned.

BarbaricManchurian · November 22nd, 2009, 10:35 PM

china is upgrading everything to higher speeds and expanding its non high-speed network in places like Xinjiang and Xizang, also many metros and suburban railways are being built. The lower-speed railways will still exist for those who can't afford the high-speed tickets, though I don't expect much additional investment besides the expansions in Xinjiang and Xizang and routine maintenance.

Do Chinese also build any additional low-speed rail lines and stations in the countryside between big towns and high speed mainlines in China proper to ensure that all places would be close to stations?

BarbaricManchurian · November 23rd, 2009, 04:12 PM

the low speed lines still exist, China's rail infrastructure pre-capitalist was actually some of the most extensive in the world

Germany has 41 000 km rail lines - almost twice that distance rail track - yet less population than Guangdong, Shandong or Henan. Which of those provinces has most rail? USA still has more than double the rail length of China, yet one quarter of the population.

Well China didn't really start to upgrade its rail system until recently. USA may have more rail length than China, but for High speed rail length China beats everyone.

Dont forget that its not really about population but how much actually needs to be covered.

Everyone lives on the East in China, not much rail in needed in the mountains right?

By area, Germany is smaller than Sichuan, and perhaps as big as say Guangdong and Guangxi combined.

West of USA is mountains and deserts too.

excessive coverage isn't really needed, US rail system was built in the 1800s where transportation was less efficient, so they needed more feeder lines and stuff. Now, trucks transport the goods the last few kilometers.

foxmulder · November 27th, 2009, 09:58 PM

Also West of China is not like California.... Population is really low. Except transportation of raw material there is no such a large demand. China is still some catching to do tough. ~13000km of HSR is a nice start

Restless · November 28th, 2009, 05:16 PM

Just to summarise

The west of China is sparsely populated. Ie. Xinjiang, Tibet and Qinghai (the pale sections on the map below)

Only about 30% (400million) of the population lives on the coast. The rest are located in the interior, which you can see is about 2x more densely populated than Europe.

Eg. Here's an example with Germany:

1. Germany
Population: 82million
Area: 357000km2
Railway: 41000km

2. Guangxi+Guizhou Provinces (at the bottom left of the map below, next to Vietnam). They have a low population density compared to other provinces
Population: 88million
Area: 412000km2
Railway: <7000km

So Guangxi and Guizhou still have a long way to go before they have a similar level of railways in place. The same applies to roads etc, but that is a separate topic.

I dont know why people are so worked up about China compared to the rest of the world, they only started reforms 1979 and no other country in history has made so much progress in such short time

Compare South Korea in 1954 and 1984. Or Taiwan in 1950 and 1980.

Restless · November 30th, 2009, 12:29 AM

South Korea, Taiwan, Japan, HK, and Singapore all had comparable 30year booms that brought them to near "developed" country status. And it was a lot easier for them because they are all much smaller than Europe (500million) or the USA (310million), so their labour shortages and the resulting wage increases happened pretty quickly.

However China has 1300million+ people, which is greater than the combined population of the Asian countries listed above, Europe and also including the USA.

So in 30years, China has only managed to raise approx 500million people on the coast to relative prosperity.

We haven't even seen the impact of the other 800million people in the interior yet because they are still behind (about 10-15years behind the coastal areas).

foxmulder · November 30th, 2009, 06:01 AM

What do you expect from a country with a population of 1.3 billion. I think Chinese boom in last 2 decade is in a class of its own. I even do not compare Japan or South Korea to China. Scale is immensely different.

Agreed.

You have to compare:
Guangdong province (Pop: 120million) with Japan (Pop: 127million)
Zhejiang province (Pop: 48million) with South Korea (Pop: 49million).

Given that 400million people are now comparatively prosperous, there are still another 250million-odd people (equivalent to 2 more Japans) that have gotten rich.

Also, bear in mind that Japan and South Korea are coastal countries, so every point in the country is no more than 100km (2hours drive) from a port.

Contrast that with China, where the most of the inland areas are over 1000km (at least 24hours drive) from any sort of port.

Wuhan-Guangzhou high speed railway on trial operation

2009-12-01

The Wuhan-Guangzhou high speed railway, which will shorten travel time from ten hours to three, will start a trial operation on December 20, www.ycwb.com reported.

It is the world's first 350-km per hour ballastless track. The train can reach speeds of 350 km per hour and can cover a 1,068.6-km distance.

Thousands of police officers have been sent to inspect the entire railway to ensure its safety, according to reports.

Such a high speed is reportedly fast enough to cause a "train whirl", which can draw people nearby into the bottom of the train. Furthermore, when the train is at its top speed, a 0.5 kg block will cause a 500 kg wallop, which can overturn the train instantly. The thirty thousand volt electricity net along the route can also pose danger to those nearby.
