On the Shanghai to Yibin route, G‑series high‑speed trains (Fuxing CR400 and CRH380 EMUs) link Shanghai Hongqiao with Yibin West via the Shanghai–Kunming High‑Speed Railway and the Chengdu–Guiyang High‑Speed Railway. These high‑speed services run at 300–350 km/h (186–217 mph) on the Shanghai–Nanchang–Changsha–Guiyang sections and around 250–300 km/h (155–186 mph) between Guiyang and Yibin, covering the journey in roughly 9 to 11 hours depending on stops at major hubs such as Hangzhou East, Nanchang West, Changsha South, and Guiyang North. Seating typically includes Second and First Class, with Business Class on many sets, plus power outlets and a dining trolley or café car. In comparison, conventional long‑distance trains (Z/T/K‑series) on older lines toward Sichuan reach top speeds of about 120–160 km/h (75–99 mph) and, depending on the timetable, arrive at Yibin or require a same‑day transfer at a regional hub; total travel time is usually 30 to 36 hours. For extra space and quieter cabins on the fast services, Business or First Class on the G‑series is the premium option.
