The Lanzhou−Xinjiang railway or Lanxin railway (simplified Chinese: 兰新铁路; traditional Chinese: 蘭新鐵路; pinyin: Lánxīn Tiělù), is the longest railway in Northwestern China. It runs 1904 kilometres (1,183 miles) from Lanzhou, Gansu, through the Hexi Corridor, to Ürümqi, in Xinjiang. It was Xinjiang's only rail link with the rest of China until the opening of the Lanzhou–Xinjiang high-speed railway in December 2014. The railway follows the path of the ancient Silk Road.
