On the Shanghai to Taihunan route, the fastest option is the G-series high-speed train running from Shanghai Hongqiao to Taiyuan South (often listed as Taiyuan Nan/Taihunan). These services are typically operated by CR400 “Fuxing” or CRH380 sets, running at up to 350 km/h (217 mph) on the Shanghai–Xuzhou and Xuzhou–Zhengzhou high-speed sections, then up to 250 km/h (155 mph) between Shijiazhuang and Taiyuan through the Taihang tunnels. Typical journey time is about 5 hours 45 minutes to 6 hours 30 minutes, with limited stops at major hubs such as Nanjing South, Xuzhou East, Zhengzhou East, and Shijiazhuang. Seating classes include Second, First, and Business, with power outlets, tray tables, and hot water dispensers onboard. In comparison, classic long-distance Z/T trains between Shanghai (main station) and Taiyuan (central station) use conventional lines at around 120–160 km/h (75–99 mph) and take roughly 12–16 hours. These offer Hard/Soft Seat and Hard/Soft Sleeper options and can be practical for overnight travel, but they usually do not serve Taiyuan South directly, so a short local transfer may be needed at the Taiyuan end.
