High-speed trains on the Shanghai to Wuxi route are primarily G-series Fuxing EMUs and D-series Hexie EMUs. Most G-series sets offer Second, First, and Business Class seating, while D-series typically provide Second and First Class. Services usually depart from Shanghai Hongqiao and arrive at Wuxi or Wuxi East. G-series Fuxing trains run on the Beijing–Shanghai High-Speed Railway and the Shanghai–Nanjing Intercity line at up to 300–350 km/h (186–217 mph). With limited stops—often skipping stations like Kunshan South—they cover Shanghai to Wuxi in roughly 30–45 minutes. D-series Hexie trains operate at 200–250 km/h (124–155 mph) with more intermediate stops such as Suzhou and Suzhou Industrial Park, bringing the journey to about 50–70 minutes. Some services serve Wuxi East instead of the central Wuxi station, so check the arrival stop. Onboard, you can expect power outlets, luggage racks, clean restrooms, and trolley service for drinks and snacks. Business Class on G-series features wider recliners (1–2–1), First Class is 2–2, and Second Class is 3–2. Choose G-series for the quickest trip; select D-series if you prefer a lower fare or need access to intermediate cities.
