G-series high-speed trains run from Shanghai Hongqiao to Tongren South (Tongren Nan), offering Second, First, and Business Class seating. The fastest services use Fuxing trainsets (CR400 series) on the Shanghai–Kunming High-Speed Railway, operating at up to 300 km/h (186 mph) on most stretches. Typical end-to-end travel time is about 6 hours 30 minutes to 8 hours, depending on stops. Many services call at key hubs such as Hangzhou East, Nanchang West, Changsha South, and Huaihua South before reaching Tongren South. In contrast, conventional long-distance trains (Z/T/K series) run from Shanghai or Shanghai South to the older Tongren station on the classic line. These services run at roughly 120–160 km/h (75–99 mph), make more intermediate stops, and usually take around 18–22 hours. They are practical when seeking an overnight option or when high-speed tickets are limited. Onboard, high-speed trains provide 2+3 seating in Second Class, 2+2 in First, and lie-flat seats in Business Class, with power outlets and trolley service. Conventional trains offer Hard/Soft Seat and Hard/Soft Sleeper accommodations plus a dining car. Choose G-series for the quickest daytime ride to Tongren South; pick a Z/T/K sleeper for an overnight trip to Tongren.
