China on Saturday opened the world’s most elevated railway (高架铁路) with the first pair of passenger trains traveling across the “roof of the world”.

Two trains set off at Golmud and Lhasa, the two start-up points of the Qinghai-Tibet Railway that is dubbed an “engineering marvel” that has linked Tibet with the rest of China for the first time.

Construction of the Qinghai-Tibet railroad is a long-cherished dream of generations of the Chinese people. A passenger train coded “Qing 1”pulled out from the Golmud station at 11:05 a.m.. Some 1,142 kilometers away, Tibet’s regional capital Lhasa saw off a train bound for Lanzhou, capital of northwest China’s Gansu Province, at 11:12 a.m.. The train, coded “Tibet 2”, carries about 700 passengers in 16 compartments (车厢) and is expected to arrive in Lanzhou in 30 hours.

Norbu, a 28-year-old Tibetan farmer from Gonggar, left home before daybreak to join the celebrations at Lhasa railway station and to catch a glimpse of the train. “I’ll board a train myself sometime to visit the inland areas.”

Trains traveling across the roof of the world, with extra oxygen pumped into the cabins to prevent passengers from suffering altitude sickness, will traverse (穿越) a mountain pass sitting 5,072 meters above sea level as it rises up to the Tibetan plateau, and will drive through the Hoh Xil, China’s largest area of uninhabited land.

The cars were installed (安装) with environment-friendly toilets, wastewater deposit tank and garbage treatment facilities to protect environment along the railroad. All the Chinese characters that appear on the electronic screen in each railway car have been translated into Tibetan and English.

The Qinghai-Tibet railway is 1,956 kilometers long, with 960 km of the track located 4,000 meters above the sea level and the highest point at 5,072 meters. The project is dubbed an “engineering marvel” because people used to think the long-lasting ice and snow along the route could never support tracks and trains.
