Locals and tourists in Tibet can already enjoy the mountainous views of this region via a high-speed train.

The 435-kilometre railway line connects the Tibetan capital Lassa with the city of Nyingchi and began operating on 25 June. But, as the television network tells CNN, build a high speed line in this autonomous region of China, dubbed the “roof of the world”, it was no easy task.

About 90% of the course, which took six years to build, is more than three thousand meters above sea level. The line has 47 tunnels and 121 bridges, which include the Zangmu railway bridge, which is 525 meters long, known for being the largest and tallest arched bridge of its kind in the world.

According to the North American station, were spent more than five billion on this line, which will ride high-speed electric trains of the Fuxing series, developed and operated by the China State Railway Group.

As they travel at very high altitudes, these trains are equipped with automated systems of oxygen supply, which maintain the levels at a constant 23.6%, slightly above the average of 21% found in normal atmospheres.

In addition, its windows are equipped with a special glass layer developed to withstand the high levels of ultraviolet rays in this region.

These trains operate at a speed of about 160 kilometers per hour, being much slower than the maximum speeds of 350 kilometers per hour possible on many other Chinese lines.

According to the CNN, the Lassa-Nyingchi line spans a disputed area between India and China and is only a small part of the rapidly expanding Chinese high-speed network. The Chinese regime sees its high-speed railway as a symbol of its economic power and its growing prosperity.
