Railway at the top of the world...

I read this article on todays paper about the 1220 mile long railway link between Qinghai, China to Lhasa, Tibet and was amazed at the engineering marvel that went into planning and building this rail link. I immediately wanted to find more information on this link and found a very informative website dedicated to this. You can get a glimpse of the world records shattered by this rail link here. Now I have one more item on my wish list and you can guess what it is..
