High-speed trains connect Shanghai with Nantong via the Hutong Railway, crossing the Shanghai–Nantong Yangtze River Bridge. Services mainly depart from Shanghai Hongqiao (with a few from Shanghai Station) and arrive at Nantong or Nantong West. Seating options include Second Class (3+2), First Class (2+2), and on select services Business Class (1+2), with power outlets and a trolley service for snacks. The fastest option is the G-series Fuxing, typically using CR300AF/BF trainsets, running at up to 250 km/h (155 mph) on this corridor. These trains make limited stops (often skipping smaller stations such as Changshu or Zhangjiagang) and cover the journey in about 1 hour to 1 hour 15 minutes, depending on the timetable. In comparison, D-series Hexie services (commonly CRH2 or CRH380 variants) operate at around 200–230 km/h (124–143 mph) and call at more intermediate stations, resulting in travel times of roughly 1 hour 20 minutes to 1 hour 40 minutes. Both service types use modern EMUs designed for stable performance on the 200–250 km/h (124–155 mph) route. Choose a G-series Fuxing for the shortest travel time; opt for a D-series Hexie if you need broader station coverage along the Shanghai–Suzhou–Nantong axis.
