416.6km/h
this figure can not even pass the CET-4 examination! :tdown:
Considering it is rainy today in Shanghai and Hangzhou, I hope CRH380 can pass 425km/h in some sunny day.:D
We may see a lot of man made marvels in next few years.
Yichang-Wanzhou railway is due to open in November 20. One of the most difficult railways in the world.
YiChang-Wanzhou railway is to open
253km takes four years and stretch over the 90-km long Yarlung Zangbo Grand Canyon. This must be a very difficult one.

Good luck to those engineers :tup:
I like this picture. It's like an air harour in the era of "Star Trek". I have to admit that Chinese engineers have been much more artistically accomplished. This train station is very beautiful. :yahoo:
Has the problem of propulsion been resolved? It is said that China's indigenous gas turbine QC185 needs another several years to mature. So I still hold a pessimistic attitude towards our destroyers' displacements. 052C+ will be bigger than 052C , but I don't think its full-load displacement...
I don't like the word "BRIC". Why do you regard Russia as an emerging economy? I mean, this is like awarding Morgan Freeman the Best New Actor Award. Russia is different from each of "BIC".:cheesy:
How many shipyards in India can build 1000ton+ warships? Can somebody list them for me?
I mean, the list above is a big plan and may require huge shipbuilding capacity.
J-10 made its maiden flight in 1998 and formally entered service in 2003.
J10B completed its maiden flight in late 2008, now you say it is ready to enter service just less than two years later? I think you have overestimated our researchers' ability.:rofl:
Mostly birds.
According to the shape of these bloodstains, I think most of them are sparrows and the like. Maybe some birds should react faster to adapt to the increased speed of our train. We can build separation nets in some sections, yet we can't build them all the way along these...
