Condition in the Qiongzhou Strait is much worse than Hangzhou Bay, so a 26km bridge would be insanely expensive, and I doubt there will be enough traffic generated in Hainan to justify the spending. Britain and France has far more passenger and freight traffic to justify the Chunnel.

Population of Hainan is over 8,6 million. Population of Hokkaido is under 5,6 millions, and Hokkaido has no high speed railways. Tsugaru Strait is narrower than Qiongzhou Strait, 19,5 km narrower, but deep (about 140 m) and nasty geology full of faults - the tunnel needs to go to 240 m below sea level.

Can't believe even Hainan island gets the HSR treatment. Amazing

According to Chinese reports, the Qiongzhou Strait Crossing Project is now near final decision among following three proposals:

1. West line: A double deck highway-railway mixed bridge with four tracks (160kph for passenger line and 120kph for cargo line). The sea crossing part is 41.3km long. Max water depth is about 50m. Its mid main span is a 1408m suspension bridge, and the north and south main spans are 1056m cable stayed bridges. Total investment is about 120 billion RMB.
2. Mid line: similar to the west line with sea crossing length shorten to 21.9km. But max water depth of 75m is more technically challenging. Total investment is about 91.3 billion.
3. Mid line railway tunnel and west line highway bridge. The tunnel is about 27.8km long. The bridge is 43km on sea, including three suspension bridges - one with 2800m main span and two with 2200m span. Total investment 137.7 billion RMB.

The completion date is expected by 2020. It seems the proposal 1 and 3 are getting more supports recently. BTW, the bridge in proposal 3 has large chance to be the world's largest bridge (in terms of main span), if Italians do not speed up their long-waited project.

USD20B sounds like a pretty reasonable price for such a project, I think since China is investing a lot in making Hainan an aerospace and military base, the tunnel/bridge combination will be the most survival plan.

Question on the CRH1

I heard that the this model have trouble running at 200km/h and mostly hovers at around 180km/h. is this true?

Isn't it supposed to run at maximum 250km/h?

yeah on paper.. but i heard that the platform for this train wasn't designed for that so it's having trouble.

just what i've heard though.

I've taken CRH1 from Shanghai to Hefei via Nanjing, and on the new stretch between Nanjing and Hefei, the train was running smoothly at around 250km/h for almost the entire distance.

Using Google Translate, the Yichang-Wanzhou railway will be open on December 22. Until January 10 there will be five pairs of passenger trains daily on the line, and after that 14 pairs.

Shall any of the 5 continue from Yichang to Wuhan on the old railway?
Shall any trains travel Chongqing-Enshi and then on Yichang-Wanzhou railway?

Well China already tried with double deck DMUs in the past decade, for example the pictures below, but most of them can only go up to 180kph, I'm sure sometime down the road a double deck CRH380 will be justified when demands start to outpace supply.

The two systems share nearly identical basic technical standards (track gauge, loading gauge, maximum axle loading, coupling, braking, etc).

In fact, whenever a North American locomotive builder ships new locomotives bound for China (also Australia and a few other places), they go to the sea port on their own wheels, coupled into their trains with their normal gear, just like any other 'native' equipment.
