Beijing–Shanghai high-speed railway in the context of "Shanghai–Nanjing Intercity High-Speed Railway"

The Shanghai–Nanjing intercity railway or Huning intercity railway (simplified Chinese: 沪宁城际铁路; traditional Chinese: 滬寧城際鐵路; pinyin: Hù–Níng Chéngjì Tiělù) is a 301-kilometer (187 mi)-long high-speed rail line between Shanghai and Nanjing, the capital of Jiangsu province. Hù and Níng are shorthand Chinese names for Shanghai and Nanjing, respectively. The Huning intercity high-speed railway largely follows the route of the preexisting Nanjing-Shanghai section of the conventional Beijing–Shanghai railway and the Beijing–Shanghai high-speed railway. Construction of this high-speed railway began in July 2008. The line went into test operations in early April 2010, and opened for full service on July 1, 2010. The line has a design speed of 350 km/h (217 mph). The journey time between the two cities has been shortened from 120 minutes to 73 minutes on nonstop trains.According to the arrangements of related departments, 120 pairs of trains are operating on the line, and the time interval between services is 5 minutes at the shortest.

The railway links major cities in the Yangtze River Delta, including Suzhou, Wuxi, Changzhou, and Zhenjiang, effectively making the southern Jiangsu city-belt operate like a single metropolitan region.
