It's mostly a question of money and time. 50-60 km tunnels below mountains or sea have been built elsewhere and most likely could be built here as well.

Well, everything is possible.

Not really. 50 years ago HS network like China is building now would have been beyond technical feasibility. Short of some catastrophe in another 50 years we'll be able to do things that are impossible or way too costly for now.

The Chinese seem to have a special knack of laying their lines so they only have to dig 5 or 10km tunnels with a quick bridge across some ravine to another 5 or 10km km tunnel. Then with tunnel teams working at the same time on each site you get the job done much faster than a single long tunnel.

I thought someone joking about building a line through there.

With the Chinese in their present mindset anything is possible in terms of construction. Considering some of their off the wall proposals like building a tunnel under Bohai bay to connect both sides of it at some 150 kms plus this seems like a piece of cake.

It might not make economic sense to build a HSR throught there but construction wise it's feasible. As someone else pointed out earlier it's nothing compared to building through Tibet.

You're witnessing the World's greatest building spree so be prepared for anything.

A few years ago there was a serious proposal to dig a giant canal from Bohai through the Gobi Desert into Xinjiang to turn it into a giant Israel. It would include a massive desalination system, powered by Inner Mongolia's coal and wind. Even by Chinese standards that was bizarre.

Then it is not an existing high speed railway and should not be a continuous blue line. It either is a high speed railway yet to open in 2014 - a dashed blue line then - or else it is a slow speed railway, and should not be on the map at all.

I had no idea they were actually building a line like this though such rough terrain. The Chinese are known for building engineering marvels, the Great Wall is a perfect example. If they can build it I say the should do it and to know that it will be a 350km/h design speed is amazing. No holding back.

It says during this phase of calibration and testing the CIT will not run faster than 160km/h.

According to this
Quote:
1.各项目年底目标和主要任务量,

(1)、南广铁路南黎段:10月22日至12月11日进行联调联试,12月12日至31日试运行。
(2)、南广铁路黎梧段:10月18日至30日进行货车试验,10月31日至12月11日联调联试,12月12日至31日试运行。
(3)柳南客专南宁东至进德段:10月26日至12月1日进行联调联试,12月2日至31日试运行试验。
2.细化各主要项目具体工程完成时间节点
(1) 南广铁路南黎段:10月5日至21日工程静态验收,10月22日至25日逐级提速,10月26日短路试验,10月27日精调,10月28日道岔侧向试验,10月29日至12月1日信号联调联试,12月2日至7日逐级提速,12月8日至9日精调,12月10日至11日拉通试验,12月12日至31日试运行试验。
(2)南广铁路黎梧段:10月5日至17日工程静态验收,10月18日至30日货车试验、精调,10月31日至11月15日逐级提速、精调和短路试验,11月16日至12月1日信号联调联试,12月2日至7日逐级提速,12月8日至9日精调,12月10日至11日拉通试验,12月12日至31日试运行试验。

(3) 柳南客专南宁东至进德段:10月5日至25日工程静态验收,10月26日至11月7日逐级提速和精调、短路试验,11月8日至25日信号联调联试,11月26日至29日逐级提速,11月30日至12月1日拉通试验,12月2日至31日试运行试验。
The original plan is to start incremental speed increase testing between Dec 2nd and 7th, and eventual start trial operation between Dec 12th and Dec 31th. But according to the Xinhua news they only started speed test on Dec 26th, that means they are slightly behind schedule and trial operation will not start until sometime mid to late January, but due to the Chinese New Year that probably will get delayed again to February.

Of course that's preferable and other people choose the same (see Florence-Bologna HS line, for example), however if nature has presented you with a big mountain chain and no ravines for an obstacle or you want to cross a sea straight then a long and expensive tunnel is your only option. That is the case for Seikan and Chunnel tunnels as well as for Gotthard and Brenner base tunnels under the Alps currently under construction. I believe there are few 30+ km tunnels in Chinas as well.

Regarding that Tianjin-Yujiapu 300 km/h railway, is it an extension of Beijing-Tianjin or a branch of Beijing-Shanghai?

It is an extension of the Beijing-Tianjin intercity line.

Tianjin gets 2 new railways this year - the 200 km/h Tianjin-Baoding high speed railway as well.

How many stations does Tianjin-Baoding high speed railway have, and is it mainly serving southern suburbs of Beijing or mainly connecting Manchuria to Shenzhen, Beihai and Baoji?

Tianjin-Baoding high speed railway is being built at 250km/h standard. However completion may be delayed till 2015. There should be 7 stations
including Tianjin West, Bazhou and Baoding. It will serve as
a connection between the Beijing-Wuhang-Guangzhou HSR
to Tianjin, and thus to Northeast and east China.
Actually it will reduce the dependence to the Beijing hub, which is the main reason it has been delayed many times. It is said that this short 120km segment on plains is the most difficult railway to build in China. There was a plan to build it since the 80s and it is still not finished yet?

Well, not ever. Since China is also building Xi'an - Chengdu HSR right now, which crosses the Qin Mountains (Qinlin).



Quote:
The high speed rail line will connect Xian, in the Wei River Valley, Hanzhong, in the Han River Valley, and Guangyuan, Jiangyou and Chengdu in the Sichuan Basin. In the Qinling Mountains, it will have 127 km of tunnels, including six over 10 km in length.[2] The railway will pass through ecologically-sensitive areas including the Taibaishan and Hanzhong Crested Ibis National Nature Reserves, which are home to the endangered giant panda, golden snub-nosed monkey, takin and Crested Ibis.
Some Pictures of Qin Mountains



The low speed version of that rail road was a monumental feat of Engineering at the time during the 1950s and at the cost of many lives.

Quote:
The Baocheng Line runs from the plains of the Sichuan Basin to the Wei River Valley. It traverses the Qin Mountains, the east-west range that divides northern from southern China. The line has 304 tunnels and 1,001 bridges, which collectively account for 17% of the total track length.





While Sichuan-Yunan HSR would have to go through this....


Though the moutains isn't as high, large or steep compared to Qin or Yan mountains, but it's endless. 70% of that HSR line suppose to be Bridges or Tunnels.

Wow....pretty amazing. Thanks for the post and pictures. Wikipedia is funny, it says the Xi'an Chengdu is supposed to be a 250km/h line in one sentence, 350km/h in the description and 300km/h in the route map. What is the max design speed supposed to be?

The max design speed is 250km/h and upgradable to 350km/h.

What would they have to do to upgrade to 350km/h(I'm guessing the overhead wires)? I always wonder how much more it costs to build a like to 350km/h standards vs 250km/h standards.
