The words “railways like massive dragons are winding among the mountains” seem particularly vivid as I travel across the “roof of the world”.

The first landmark to catch my eye is the splendid Qingshuihe Bridge, the world's longest bridge built over permafrost. Look! A group of Tibetan antelopes is moving under the bridge, with some stopping to eat grass at their leisure. Thirty-three passages have been built under the railway to allow the animals to move safely and freely in their natural habitat. Wild animals such as these Tibetan antelopes have now been using these passages for years. They seem totally unaware that we are speeding past at over 100 kilometres an hour.
To prevent damage to wetlands and grasslands, 675 bridges with a total length of about 160 kilometres were built between Golmud and Lhasa. We even moved 140,000 square metres of wetland to a new area in order to protect its distinct ecosystem.

Cuona Lake is so close to the railway that I want to reach out and touch its pale blue mirror-like surface. Water birds playing in the lake, and cattle and sheep wandering the grasslands bring the scenery to life.
