All high-speed trains on the Shanghai to Gaoyou route offer Second and First Class seating, with select G-series sets also providing Business Class (1+2 layout). The quickest itineraries pair a G-series Fuxing service from Shanghai Hongqiao to Zhenjiang South—running up to 300 km/h (186 mph), with some sets rated for 350 km/h (217 mph)—and a D-series Hexie train on the Lianyungang–Zhenjiang High-Speed Railway to Gaoyou, which operates up to 250 km/h (155 mph). With a well-timed transfer at Zhenjiang South (or sometimes Yangzhou East), the end-to-end journey is about 2 hours and 40 minutes to roughly 3 hours. By comparison, itineraries that remain on D-series trains for more of the route (cruising at 200–250 km/h (124–155 mph)) make additional intermediate stops via Suzhou, Wuxi, Changzhou, and Zhenjiang, and typically take around 3 to 3 hours and 30 minutes. Onboard amenities on both G- and D-series include power outlets, tray tables, clean restrooms, and overhead luggage racks. Choose the G + D combination for the fewest stops and shorter travel time, or all D-series services for broader regional access while still maintaining high-speed performance.
