G-series high-speed trains link Shanghai and Zaozhuang via the Beijing–Shanghai High-Speed Railway, with most departures from Shanghai Hongqiao. The fastest services are Fuxing sets (CR400AF/BF) operating at up to 350 km/h (217 mph) and completing the trip in roughly 3 hours with limited stops. Other G-series runs, often using Hexie units (CRH380A/B) capped at 300 km/h (186 mph), typically take about 3 hours 20–40 minutes as they call at major hubs such as Suzhou North, Nanjing South, Xuzhou East, and Qufu East. Seating options include Second, First, and Business Class; Business offers lie‑flat seats, while First and Second provide wide reclining seats with power outlets. In contrast, conventional Z/T/K services on the parallel Beijing–Shanghai railway run at around 120–160 km/h (75–99 mph) and usually take 7–10 hours. These trains generally depart Shanghai Railway Station and arrive at Zaozhuang’s classic line station, offering hard/soft seat and hard/soft sleeper options. Travelers prioritizing the shortest journey time should look for the limited‑stop Fuxing G trains, while those seeking overnight or budget-friendly choices may consider the slower conventional services.
