The Suining–Chengdu railway or Suicheng railway (simplified Chinese: 遂成铁路; traditional Chinese: 遂成鐵路; pinyin: Suì chéng tiělù) is a double-track, electrified railway in Sichuan Province of southwest China. The railway is named after its two terminal cities, Suining and Chengdu, and forms a segment of the Shanghai–Wuhan–Chengdu passenger railway. It was built as part of the Dazhou–Chengdu Railway. A second, more direct track was opened on the Chengdu–Suining section of that line on 1 April 2006 that allows trains to reach a top speed of 200 km/h. On 7 July 2009, the high-speed track was duplicated and these two tracks were subsequently designated as the Suining–Chengdu railway. The original low-speed, single track line between Chengdu and Suining remains as part of the Dazhou–Chengdu railwa
