Hu opens world's highest railway

BBC: Chinese President Hu Jintao has opened the world's highest railway, describing it as a "magnificent feat".
The Qinghai-Tibet line boasts high-tech engineering to stabilise tracks over permafrost and sealed cabins to protect passengers from the high altitude.

What's with all the fuss about this, I think it's amazing :) , although it might ruin the Tibet culture altogether :(
