High-speed trains on the Beijing to Suzhou route run primarily from Beijing South (Beijingnan) to Suzhou North (Suzhoubei) via the Beijing–Shanghai High-Speed Railway. G‑class services offer three seating options—Second Class, First Class, and Business Class—covering the roughly 1,200 km stretch with reserved seating throughout. The fastest high-speed option is the Fuxing service (CR400AF/BF), designed for up to 350 km/h (217 mph) on this corridor. With limited stops at major hubs such as Jinan West, Xuzhou East, and Nanjing South, typical end-to-end times range from about 4 hours 15 minutes to 4 hours 35 minutes. In comparison, Hexie services (CRH380 series) usually operate at 300–310 km/h (186–193 mph) and make more intermediate stops, bringing journey times to roughly 4 hours 45 minutes to just over 5 hours. Both high-speed types provide modern interiors, power outlets at seats, trolley catering, and hot water dispensers, with Business Class offering a 1+2 layout and wider reclining seats. Note that most G‑class trains serve Suzhou North on the high-speed line; a smaller number of slower D/Z services run to Suzhou (main) via the conventional network, with speeds up to 250 km/h (155 mph) for D‑class and substantially longer travel times if you prefer an overnight option.
