High-speed trains connect Shanghai Hongqiao to Siyang Station with a mix of G-series Fuxing and D-series Hexie services. The fastest option is the G-series Fuxing (CR400/CR300), running up to 350 km/h (217 mph) on the Shanghai–Nanjing high-speed section before continuing at up to 250 km/h (155 mph) toward Siyang via Jiangsu’s regional high-speed lines. Typical stopping patterns include major hubs such as Suzhou North, Wuxi East, Nanjing South, and Huai’an East, with end-to-end travel times usually around 2 hours 40 minutes to 3 hours depending on stops. D-series Hexie trains cover the same route at 200–250 km/h (124–155 mph), making more intermediate calls and sometimes requiring a change at Nanjing South or Huai’an East; these trips generally take about 3 to 3.5 hours. Both train types offer reserved seating, power outlets, hot water dispensers, and trolley service. G-series Fuxing sets usually provide Second, First, and Business Class, while D-series Hexie services typically offer Second and First Class.
