Qinghai Tibet Railway 13 images Created 14 Sep 2011
The Qinghai Tibet Railway is the world's highest railway. The Golmud-Lhasa section zigzags more than 1000 kilometers across the Kunlun and Tanggula mountain ranges - about 500 kilometers of the tracks run on frozen earth, considered a marvel of train technology and engineering. The maximum train speed can reach 100 kilometers per hour in the frozen earth areas and 120 kilometers per hour on regular terrain but it sometimes slows down to take in the majestic landscape on one of the world's great train adventures.
