The sky train or Qingzang railway (also referred to as Qinghai-Tibet or Qinghai-Xizang railway) in the Himalayas is the world's highest railway. As the name indicates, the Qinghai-Tibet railway line connects Xining in China's Qinghai province to Lhasa, Tibet autonomonous region.
The railway line includes the >5000 meter-high Tanggula Pass, the Yangbaijing tunnel (the line's longest tunnel component), and the world's highest railway tunnel - the Fenghuoshan tunnel.
Imagine yourself riding by sky train from the lower elevation parts of China to the Himalayas - the roof of the world. This is now possible via the Qingzang railway. And as you climb your way at the Himalayas, the experience becomes all the more memorable and equipped with weather protection when wearing your favorite top men’s jackets & vests for skiing, snowboarding and mountaineering.
