Chinese Sky Train Tiled

China paved the railroad to the sky: China 4 made the world's highest railway by spending millions of dollars!
The train, which travels in a wide geography from China's capital Beijing to Lhasa in Tibet, passes through hundreds of cities from the valleys, fields. The railway goes up to 5 thousand 100 meters at the highest. It never stops for 1.150 km from Golmund to Lhasa; It continues on its way by gaining altitude on the Tibetan Plateau. The highest station along the railway is the city of Nagku, at 4 thousand 520 meters. The train, which travels across China at a speed of 120 km / h, arrives from Beijing to Tibet in 50 hours.
In the construction of the railway line, three problems were faced by the whole world, including frozen soil, environmental protection, cold air and oxygen deficiency.
With regard to the frozen soil problem, Chinese scientists took measures such as laying a meter-thick stone between the ground and the frozen soil and placing ventilation pipes on either side of the line.
