青藏铁路是世界上最高最长的高原铁路，全长1956公里，其中有960公里在海拔4000多米之上,是连接西藏和中国其他地区的第一条铁路。由于铁路穿越世界上最脆弱的生态系统,在建设期间和建成后都采取了生态保护措施,以确保其成为一条“绿色铁路”。青藏铁路大大缩短了中国内地与西薄之间的旅行时间。更重要的是,它极大地促进了西藏的经济发展,改善了当地居民的生活。铁路开通后,愈来愈多的人选择乘火车前往西藏,这样还有机会欣赏沿线的美景。

　　The 1,956-kilometre Qinghai-Tibet Railway is the world's highest and longest plateau railway with 960 kilometres above the altitude of 4,000 metres, and the first train line to join Tibet and other areas of China. As it crosses the world' s most vulnerable eco-system, continuous ecological protection measures have been adopted during and after the construction to guarantee "a green railroad.” The Qin-ghai-Tibet Railway substantially shortens the travelling time between inland China and Tibet, and, more importantly, considerably promotes the economic development of Tibet and improves the living condition of the local people.  Afterthe railway' s operation, more and more people choose to visit Tibet by train so that they have the opportunity to admire the beautiful scenery along the way.
