On the Shanghai to Xingwen route, the quickest option combines China’s high-speed G-series trains with a short regional leg. From Shanghai Hongqiao, CR400 “Fuxing” and CRH380 sets run on the Shanghai–Kunming High-Speed Railway at 300–350 km/h (186–217 mph), then continue over southwest segments that typically operate at 250–300 km/h (155–186 mph) toward key hubs such as Changsha South, Guiyang North, and Yibin West. After reaching the Yibin area, the final section to Xingwen is on a non–high-speed line at about 120–160 km/h (75–99 mph). Total travel time on this fast combo is usually around 12–14 hours with one or two changes. Seating on G-trains includes Second, First, and on some services Business Class. By comparison, conventional Z/K trains from Shanghai (often from Shanghai South) use classic routes at roughly 120–140 km/h (75–87 mph), with hard/soft seat and sleeper options. These services generally require a transfer near Yibin or Luzhou to reach Xingwen and take far longer overall—typically about 30–35 hours. Travelers prioritizing speed should select the G-series plus regional connection, while those preferring overnight sleepers may opt for the classic Z/K services.
