Shanghai–Suzhou–Nantong railway, abbreviated as Husutong railway[1] (Chinese: 沪苏通铁路; pinyin: Hù-Sū-Tōng tiělù, "Hu", "Su" and "Tong" being the abbreviations for Shanghai, Suzhou and Nantong, respectively) is a higher-speed railway in China's Yangtze River Delta area, connecting Shanghai, the region's main city located south of the Yangtze, with Nantong in Jiangsu province, north of the river.

The railway is 143 kilometres (89 mi) in length and traverses several county-level cities in Suzhou Municipality of Jiangsu along the south bank of the Yangtze including Zhangjiagang, Changshu and Taicang.

The railway crosses the Yangtze River over the new Hutong Yangtze River Bridge between Nantong and Zhangjiagang, a double-deck bridge with a 4-track railway on the lower deck and a six-lane roadway on the upper deck.

The new bridge thus greatly improves the railway connections between the Central Jiangsu (the region north of the Yangtze) and the Jiangnan, in particular Shanghai.

On its way between the new bridge and Anting, the railway has brought rail service for the first time to prosperous communities on the southern bank of the Yangtze such as Zhangjiagang, Changshu, and Taicang which had no railway connection.
