Suining–Chongqing railway is a high-speed railway connecting Chongqing and Suining, Sichuan as part of the Shanghai–Wuhan–Chengdu high-speed railway. It is also known as Suiyu railway, following the Chinese practice of combining the shortened version of the terminal city's name. It is a national grade I railway with two electrified lines, with a designed maximum speed of 200 km (120 mi).[citation needed]

Overview[edit]

The railway has a total length of 128 km (80 mi), 31 km (19 mi) of which is in Sichuan Province and 97 km (60 mi) within Chongqing Municipality.[citation needed] It is classed as a national railway grade I, with two electrified lines, designed for maximum speed of 250 kilometers. The second stage of the railway on December 31, 2012 officially launched operations.

History[edit]

Suiyu railway commenced with a ground-breaking ceremony on February 25, 2003.[citation needed] Stage one of track laying across the board was completed on April 23, 2005. Stage one was opened on April 1, 2006 after a total investment of 4.925 billion yuan. Suining–Chongqing railway is one of China's high-speed rail project pilot projects, building China 's first track test section for ballastless high-speed trains for a length of 13.16 km (8.18 mi). The trial was commenced in September 2004, taking until January 2007 to complete the test.

During May 2005, Suiyu railway trains reached a top speed of 225 km/h (140 mph) in testing. The railway is part of Chengyu high-speed railway and achieved connection with the railway from Chengdu to Suining.[citation needed] The combined operating distance from Chongqing to Chengdu is only 312 km (194 mi), the entire running time of about 2 hours. On September 26, 2009, at Chongqing North Railway Station started services bound for Chengdu with CRH1 Harmony EMU trainsets, allowing Southwest China to enter the high-speed rail era.[1]

The second stage of the Suining–Chongqing railway line has a length of 131 km (81 mi), of which 37 km (23 mi) is in Sichuan Province, 95 km (59 mi) in Chongqing Municipality.[citation needed] This saw the creation of Suinan South station and a new alignment from Aikawa to Shizhishan. Work on this upgrade commenced on January 18, 2009, with construction lasting for four years. This stage of the project was estimated to need a total investment of 4.81 billion yuan.[2] Chongqing railway new tier on January 24, 2013, officially launched operation.[3]
