High-speed G-series services (CR400 Fuxing and late-model CRH) link Shanghai Hongqiao with Chibi North via Nanjing South, Hefei South, and Wuhan. The fastest sections operate at up to 350 km/h (217 mph) between Shanghai–Nanjing and Wuhan–Chibi North, while the Nanjing–Hefei–Wuhan stretch typically runs at 250 km/h (155 mph). Many trips involve a simple change at Wuhan; selected through trains may also stop at Chibi North. End-to-end travel usually takes about 4.5 to 5.5 hours, depending on stops and connections. Seating classes on G-series trains include Second, First, and Business, with power outlets, tray tables, and a trolley or dining car for hot meals and snacks. By comparison, D-series high-speed trains (CRH) cover much of the same route at 200–250 km/h (124–155 mph) with more intermediate stops, leading to journey times of roughly 6.5 to 8 hours. Traditional Z/K services on the conventional line reach 120–160 km/h (75–99 mph) and typically use Chibi (city) station rather than Chibi North; these take around 11 to 14 hours and offer Hard Seat, Hard Sleeper, and Soft Sleeper options. Travelers focused on the shortest time should look for G-series itineraries, with D-series and conventional trains providing lower-cost alternatives.
