The Qinghai-Tibet Railway，which runs from Xining City to Lhasa City，with a total length of 1956km，has far-reaching effects on promoting the sustainable socioeconomic development of Qinghai and Tibet. The Xining-Golmud Section was put into operation in 1984，and the construction of the Golmud-Lhasa Section，with a total length of 1142km，was started in June 29，2001. This section was put into operation in July 1，2006. Three major global engineering problems- permafrost，alpine and anoxic as well as ecological fragility-were overcome during the construction of the Qinghai-Tibet Railway. The construction technology reached the contemporary international leading level. At the same time，a great number of pioneering contributions were made to environmental protection and the harmony between man and nature was realized. The Qinghai-Tibet Railway Project won the Special Class of 2008 National Science and Technology Progress Award，and the Excellent Class of the international FIDIC Centenary Awards in 2013.
